Installation and configuration of software for working with a CNC machine

1. Computer requirements.
A well-selected and configured computer is the key to stable operation of the machine, so the choice of a control computer should be taken seriously and carefully. To operate a machine running Mach3 you need: a processor with a frequency of at least 1 GHz, RAM of at least 1 GB. As operating system It is best to use Windows 7 32-bit version, since under this OS the computer works quite stably and is relatively easy to configure. Allowed using Windows XP/Vista/8/10. Only 32-bit (Win XP/7) operating systems are suitable for working with the machine via the LPT port. If there is no LPT port or its incorrect operation, the computer can be used with a USB-LPT adapter. The USB-LPT adapter works with both 32 and 64 bit Windows operating systems.
Incorrect operation of the LPT port is expressed in unstable speed of movement of the machine along the axes, knocking of the motors and skipping steps, unplanned stops while moving. The stability of LPT operation depends on how well the drivers for the computer's motherboard are written by the manufacturer. It also depends on the specific configuration of the system unit as a whole. It is possible to check the quality of operation of an LPT port only when direct work with the machine (the procedure is described in paragraph 6 of this manual).
Only the operating system must be installed on the computer intended for installation of control software. Windows system. Apart from the operating system and device drivers, no other programs should be installed. Antiviruses, various utilities and programs can interfere with the operation of the Mach3 program in real time, pulling the “process priority over,” which in turn negatively affects the stability of the machine as a whole. The operating system should be preinstalled on drive “C” by default. Computer components must be in good working order technical condition.
You can find out the characteristics of your existing computer: Start>Computer (right-click)>properties. The window that opens will display the basic characteristics (Figure 1/Figure 2).

2. Mach 3 Installation
All necessary files for installation and configuration of the machine can be obtained upon purchase of the machine, upon request by e-mail, or by following the link:
Let's launch installation file"Mach3Version3.043.022." Click “Next”/“yes” everywhere. When the installation is complete, the computer should restart automatically; if this does not happen, restart manually. Extra shortcuts"Mach3Plasma", "Mach3Mill" "Mach3Turn" can be removed from the desktop (Figure 3). Leave only Mach3 Loader.

Figure 3

3. Setting the machine profile
After installing Mach3, run the profile installation file (links to profile installer files are sent via e-mail when sending the machine) Setup LPT when working under control via the LPT port. Or Setup USB, if a USB-LPT adapter Modelist USB-LPT or an Ethernet controller Modelist -L1 will be used.
This installer was specially designed to automate and simplify the machine setup process. Profile installation program in automatic mode installs a machine profile for “Setup LPT” or a machine profile and adapter plugin for “Setup USB”. Installing the Modelist USB-LPT adapter drivers and setting up the network connection for the Modelist-L1 Ethernet controller is carried out by the consumer independently according to the operating manual or instructions on the website:
- « »;
- “Connecting the controller using an Ethernet-LPT adapter.”
Note: Machine profiles for working with adapters from “Setup USB” are supplied with the microstep multiplier N=4 installed and do not require additional configuration.
After launching the profile installer, a list of machines will open, in which you can select yours, enter its serial number from the keyboard and press ENTER. For example, in the picture (Figure 4) the profile of the Modelist-6090 machine is selected. If the profiles are successfully installed, “files copied: 1” should be written at the bottom (Figure 1). Close the profile installation window. The profile installer program automatically creates a shortcut on the desktop, and you can always easily return to it if you need to select a profile for another machine, or you make a mistake with the choice.
Automatic installation profile and adapter plugin are valid only when Mach3 is installed on the “C” drive. If the operating system is installed on another disk, the profile and plugin must be copied manually.

3) The size of the working field in centimeters, for example 4060 - the size of the working field along the X axis is 40 cm, along the Y axis - 60 cm.
4) Additional index reflecting the optional properties of the machine. Index 4X and X4 - indicates presence in profiles additional settings for working with a rotary axis. Index Z - profiles for machines with a caprolon screw nut along the “Z” axis. Index AL/S - with an aluminum or steel frame (not indicated in the marking of large machines).

4. Installation of drivers for the USB-LPT adapter produced by CNC-Modelist.
If your computer has a 64-bit WindowsXP, Windows7, WindowsVista or Windows 8/10 operating system installed, then it is not possible to control the machine via the LPT port.
If you plan to work through an LPT port, skip this step.

If Windows 8/10 is installed on your computer, then before installing drivers for the USB adapter, you must install a special certificate. How to do this is described in the instructions: “Step-by-step instructions for installing a certificate and drivers for a USB adapter in Windows 8 (Windows10)

Connect the USB adapter to the computer. After the operating system detects the adapter, we begin installing the drivers. Open “Control Panel”> “Device Manager”, find in the “Other devices” section - CNC controller, Figure 6.

Figure 6.

Right-click on it and select "Properties" and click the "Update Drivers" button. In the window that opens, select the item “Search for drivers on this computer (Search and install drivers manually).” Specify the path to the folder with drivers.

Figure 7.

Click the “OK” and “Next” buttons. After installing the drivers, the adapter is ready to use. Installation software completed.
Download drivers and find more detailed description The driver installation process can be found in the instructions “Connecting a controller using a USB-LPT adapter”

5. First launch of Mach3
Open Mach3 Loader. In the list that opens, select the profile of your machine and click “Ok” (Figure 8).

Figure 8

When installing USB drivers adapter, the control source selection window appears, Figure 9, in which you must select work via mach3USB to work with the USB-LPT adapter.

Figure 9

Or Normal Printer port to work through the LPT port, Figure 10

Figure 10

Go to the main window of the Mach3 program (Figure 11).

Figure 11.
On at this stage the machine must be fully connected according to the instructions for the first start, the power is turned on, etc. In the main window of the MACH3 program, press the “Reset” key so that the frame around it does not blink and lights up green, (Figure 11). At this moment, the stepper motors should fix their position (you will hear a click) and make a slight noise.
When using a USB-LPT adapter, when you press the “Reset” button, the following message may pop up when you turn on the Mach for the first time (Figure 12):

Figure 12
We ignore it, click “OK”, and click “Reset” again. If the message appears several times in a row, check its correctness USB connections adapter for computer.
Now, by pressing the arrows on the keyboard (left, right, up, down), we observe movement along the axes on the machine, and on the screen, a change in coordinates in the X Y fields at the top left, to move along the Z axis, the PageUP, PageDown buttons. You can also call up the on-screen movement control panel by pressing the "Tab" key on your computer keyboard (Figure 13).

Figure 13.
If the direction of movement of the machine portal does not coincide with the direction of the keyboard arrows, for example, when pressing the "<» инструмент движется в право, изменить направление можно в меню Сonfig->Port and pins->Motor outputs by checking the DirLowActive box opposite the desired axis, Figure 14.

Figure 14.

6. Checking the correct operation of the computer's LPT port.
When working with a USB-LPT adapter, you can skip this point.
The difficulty with the LPT port is that almost all modern motherboards have a means of changing operating frequency processor when the load on it changes. At the same time, all ports also experience fluctuations in frequency - as a result, the motor control signals “float” in frequency or can be completely turned off for a short period of time, that is, when Mach3 is running, the frequency of the step signal changes, which leads to uneven movement of the working part of the machine - jerking, hitting and even stopping.
Checking the LPT port.
To do this, we move the move 3-4 times in manual movement mode (using the keys< >iv^) for the full length of the work table. The movement should occur smoothly at a constant speed, without jerking, jerking, hitting or stopping (example video). If when moving there is local changes speed of movement and/or stopping during the movement of the portal, then to check it is necessary to change the Velocity parameter in the Config > MotorTuning menu item, reducing it by 10 times - Figure 15.

Figure 15.
If changes in movement speed decrease and stops stop, but at the same time impacts and shocks persist, then this motherboard not suitable for controlling the machine via the LPT port.

7 Optimizing the computer for working with the machine.
After successful implementation After all the previous points, you need to close everything, restart the computer and perform basic optimization of the computer.
1) Disable automatic update. Let's go to Start? Control Panel? Center Windows updates? Settings. Disable all updates and click “Ok” (Figure 16).

Figure 16
2) Set up a power plan. We prohibit turning off the screen, hard drive and USB ports. Let's go to Start? Control Panel? Power supply? Setting up a power plan? Change advanced power settings. Enter the settings as in Figure 17. Don’t forget to click “Apply” and “Ok”.

3) Configure user account control settings. To do this, in the “Start” menu, enter “control” in the line and select “Change user account control settings” (Figure 18). In the window that opens, drag the slider all the way down and click OK.

Figure 18

Figure 19
4) Remove the swap file. To do this, go to Start>Computer (right click)>properties> Extra options systems. In the window that opens, select the “Advanced” tab, and in the Performance item, click the “Options” button (Figure 20).

TP-LINK is one of the leading manufacturers of network equipment. We will present detailed information, how to connect or reconfigure a TP-Link router. The procedure for connecting the device, settings for wired and wireless network, password changes and firmware updates. The information obtained will allow you to configure without problems home network in TP-Link routers.

What data is needed to connect the router?

To change the parameters of the router itself, you will need two things: a browser and a password with an access login. The latest data can be found on the label attached to the device body. As a rule, the standard login and password are the English word admin.

To use the Internet you will also need authorization data, which you must obtain from your provider. However, they must be specified in the service agreement. They must be entered in the router or a specialized program, if provided by the provider. Be sure to find out the connection type (PPPoE, L2TP, PPTP and others) for correct settings. When using a dynamic IP, you need to know your IP address, subnet mask and the like. If all these parameters are already in hand, you can connect to TP-Link.

How to connect a device to a network, PC or laptop

The procedure does not cause any great difficulties, and is performed for 5-10 minutes. Follow the steps in the following instructions one by one:

Models with Wi-Fi can be configured over the air. This is relevant if you are not able to connect the router to your computer via LAN. This completes the manipulation of the wires. The process then continues in the web interface.

Login to the web interface

Manipulations with the modem are performed only in the web interface. You can access it from a computer with a network cable connected or via Wi-Fi on a wireless model. Attention! You can use the interface at any time, even when the Internet is down. To log in, follow the instructions below:

Router settings

Let's move on to the most interesting part - changing the router parameters. The main window contains more than 10 different sections. Most of them are not needed by the average user. Internet activation occurs in a maximum of two sections. Next, we will tell you in detail how to configure a TP-Link router, about creating wired connection, setting up Wi-Fi, changing the login password and other useful things.

Connecting to a wired network

The router has a quick setup feature. Beginners are recommended to use this section. Click "Next" and follow the installer prompts:

When setting up other types of connections, fields for entering your login and password will appear. Here you need to enter the data provided by the provider. The user can change the settings in the “Network” section. IN selected models“TP Link” next to the choice of connection type there is a “Define” button that will help you find out your type. Based on the WAN, the corresponding characteristics are already configured.

For example, to use PPPoE, fields for login/password and parameters specific to PPPoE already appear in the window.

Connect via wireless network

For devices with a Wi-Fi module, you will also have to configure wireless connection. This can be done with quick setup(the penultimate paragraph requires the introduction of all important parameters).

Let's figure out what Wi-Fi settings you have TP-Link router should be changed. Broadcasting should be set to “on”. The SSID or network name is what will appear on other devices when searching. Specify your region, mixed mode. Leave the channel and its width automatically. Advanced users can choose it themselves, taking into account occupied channels by neighboring routers. If you want to set a password for the access point, select the WPA2-PSK security type. Finally, all that remains is to enter the password for wireless point networks. Click the “Next” button and complete the process.

Similar settings are found in the “Wireless Mode” section. To change the SSID or channel parameters, select the “Settings” sub-item wireless mode" You can change the password in the “Wireless Security” section. When making any changes, do not forget to click the “Save” button. If the selected settings have not changed, reboot the device.

Through these menu items, routers from the manufacturer TP-Link are configured.

Changing the password for logging into the web interface

All owners are recommended to change standard password and login from the router. This is due to the fact that an attacker, if the Wi-Fi password is missing or has been hacked, will be able to enter the modem settings and “have fun”. Eliminating the problems created will not be difficult, but it is better to avoid this. The interface allows you to quickly and conveniently change input data:

If you have forgotten your login information, perform a factory reset.

Advanced Settings

The router has a mass additional functions, which expand its capabilities. Consider some of the advanced settings:

Guest network. Allows you to configure a public guest network, limit incoming/outgoing traffic or operating time.
Changing addressing. It allows you to set static IP addresses or use DHCP.
Forwarding – setting up virtual addresses, web telephony, conferences and the like.
Functions parental controls. Limiting Internet access time or specific resources.
Manually setting a routing table (for specialists).
Binding MAC addresses to specific IPs.

You can find out more about how to configure specific functions of your TP-Link router in the instruction manual.

VPN

This technology allows you to hide information from prying eyes. Encryption is performed, so even your provider will not be able to track your visits. However, only those models that have a pre-installed VPN server can use VPN. You can perform the setup using the following steps (for English firmware).

From time to time, some subscribers wonder how to order Internet settings on MTS. Every modern client of the mentioned mobile operator should know about this. After all, the Internet has become an integral part of human life. And without it, working with mobile devices is not particularly useful.

How to connect the Internet on a smartphone from MTS? What tips and tricks are there regarding this topic?

Activation methods

You can order MTS Internet settings for your phone different ways. There are several options for the development of events:

by simply inserting a SIM card into the phone;
via SMS command;
using the "Personal Account";
by making a call mobile operator;
manually.

The last technique is not used very often. Therefore, you have to think about how to order automatic settings Internet on MTS.

SIM card and smartphone

The first and simplest scenario is to start working with the phone and new SIM card. Typically, subscribers are offered automatic settings and MMS. And they will need very little:

Insert the MTS SIM card into the phone.
Turn on your mobile device.
Wait a few minutes.
Save message with automatic settings.

An SMS from the operator arrives a few minutes after turning on the mobile device. But sometimes this operation is not carried out. What then? You will have to order settings for mobile network on one's own.

SMS command

For example, you can use a fairly common approach to solving the problem. So, solving the problem of how to order Internet settings on MTS in Russia, you can act according to the following instructions:

Start writing a new message on your phone.
Write the word in the text of the letter internet.
Send a message to number 1234.
Open the SMS that will come in response to this request.
Save the settings published in the message. In this case, you need to open the settings in the SMS menu and select the appropriate function.

All that remains now is to restart your mobile device. The settings will take effect automatically. Now you can use it easily mobile Internet on the phone.

Full connection

How to order Internet settings on MTS along with MMS? To do this you will have to act in exactly the same way as in the previous case. The difference is that the SMS request will be slightly modified.

In this case you will have to send to short number 1234 empty letter. Next, as in the described circumstances, it is proposed to save the changes and reboot the smartphone.

Phone calls

The next trick on how to order Internet settings on MTS is to make a call to a mobile operator. This approach has several ways of implementation. Namely:

Making a call to number 0876. After which the subscriber will receive automatic settings for the Internet and MMS in a message. They will need to be saved.
You can also call 0890, wait for the operator to respond, and ask him to send Internet settings to a particular number. A call center employee will fill out an application and send the parameters via SMS.

That's all. The methods listed are absolutely free. They can be used at any time. Typically, a response message will be sent to the smartphone within a few minutes after the request is processed. Therefore, you won't have to wait long.

"Personal Account" and Network Settings

The next approach to deciding how to order Internet settings on MTS is to work with the “Personal Account” of the subscriber of the mentioned mobile operator.

Step-by-step instructions for setting up a mobile Network on a smartphone via the Internet are as follows:

Open the official website of the operator.
Log in to your “Personal Account” using your previously received login and password.
Open the section "Access Control" - "Settings" - "Internet and MMS".
Specify the phone number to which you want to send the Network parameters.
Select the settings transferred to the smartphone.
Confirm the operation.
Wait for an SMS with the settings.
Open the parameters of the received message and select the "Save" function.
Reboot your phone.

The described algorithm of actions helps without special problems order certain network settings from MTS through the “Personal Account”. This technique is not suitable for subscribers who do not have the appropriate profile. You can start it up in a few minutes.

Manual setting

The previously proposed methods help to order MTS Internet settings on Android " and other OS. You can take a more difficult route - set the appropriate parameters manually.

To do this you need:

Go to the “Settings” section on your mobile device.
Select "More" - "Mobile networks" - "Network access points".
Click on the button responsible for adding a new access point.
Specify Network settings. We will talk about them below.
Check the box next to "Data transfer".
Save Network settings.

It is done! As you can see, everything is not as difficult as it seems. And anyone can configure the Network manually modern subscriber, even a schoolboy.

Settings for manual addition

As we have already said, for manual settings Network on a mobile device, you need to enter certain data in a special menu item. That is, when thinking about how to order Internet settings on MTS, a subscriber can try to write the following information in the access points:

Name - MTS Internet;
APN- internet.mts.ru;
password - mts;
login - similar to password.

That's all you need to write in earlier specified section settings. After saving these parameters, you can easily use the MTS mobile network.

Attention: the remaining fields at APN points do not need to be filled out. Otherwise, the settings will not work fully.

Finally

We found out how you can order MTS Internet settings on your phone. The instructions provided will help you cope with the task.

As practice shows, there is usually no need to order network parameters separately. After starting to work with the SIM card mobile operator will still offer to automatically configure access to MMS and the Internet on your smartphone. This is normal. Subscriber reviews indicate that all of the previously listed instructions work equally well. And therefore there is no difference in which technique is used.

Can I be charged money for sending a request under any circumstances? No, getting settings for the mobile network from MTS is completely free. The operator does not charge a fee for such a service.

Yandex.Metrica is free tool to analyze your website visitors. It will allow you to see where visitors are coming from and what they are doing on the site.

In order for you to effectively use Yandex.Metrica in your work, we have prepared instructions for installing, configuring and using it.

INSTALLING A COUNTER ON THE SITE

First, register an account in Yandex, in other words, you need to create mail. If you already have it, go to the page Yandex.Metrics. Next, click the Add counter button. Enter the Counter Name in the field Domain name indicate the domain of your site. If your site is hosted on several domains, then add them to the Additional domains field.Check if your time zone is set correctly. On the right top corner click the Create button.

Go to the Counter Code section. We set the checkbox in the items Webvisor, scroll map, form analytics and Asynchronous code. If you do not want other users to see your statistics, then we recommend not enabling Informer. Click the Save button.

Then we copy the counter code and place it on our website. In the site management system, go to the Statistics section and paste the Yandex.Metrica code into the Script code window for other statistics, for example Yandex.Metrica. Click the Save button.

Congratulations! We have completed the first stage - installing a counter on the site.

THE MOST IMPORTANT THING IS GOALS

The next stage is creating goals. Each site has a different goal or set of goals. If you run a blog, then it is important for you that users view more pages on your website. If you have an online store, then you need to know which users are buying your product or planning to do so. If you are a photographer, designer, artist, then it is important for you to find out everything about users who are interested in your contact information.

On the My counters page, click on the gear on the right and on the page that opens, select the Goals section.

In Yandex.Metrica, you can create goals in four different ways:

1. Page views. Setting this goal allows you to specify a certain number of pages that a site visitor has viewed. We indicate the name of the goal, the number of pages that the user should view and click on the Add goal button.

2. Page URL.In the settings for this goal, you can specify a specific page or set of site pages that you would like to visit.

For example, such pages could be an order confirmation page, a Contact page, or a directions page.

3. Event.Setting up this goal allows you to specify an event on the site, which is an indicator of the site's performance. For example, clicking the “Place an order” button. To set up this goal, please submit a support request at Personal account asking you to set the target in the source code on a page on your site. The request must indicate the name of the goal in the format yaCounterXXXXXX.reachGoal('TARGET_NAME');

Where:
XXXXXX — your meter number;
TARGET_NAME — target identifier (a word that denotes an event on the site selected as a target action). For example, ORDER.

This article was written specifically for people who have not previously worked with the Linux operating system. However, despite this familiarization with it, it will also be useful for experienced users, since it contains information that is not known to everyone.

In the event that the operating room Linux system is not installed on a PC or other device used, you must first download it from the official portal stable version. According to the statement of most experts, the LTS version is considered the most stable, and not any other that was released later.

There are several versions of the operating system installer that differ from each other:

i386 – version designed for installing a 32-bit system;
amd64 – 64-bit version;
desktop – the operating system is loaded in LiveCD format, and installation will be done from there;
alternate – are images that have a text installer, which is very convenient when installing the OS on old computers, as well as for configuring the system during the installation process.

For those users who perform Linux installation first, best choice will become desktop.

Once the boot process is complete, the operating system can be installed in several ways:

using a DVD on which an image has previously been created;
with help bootable flash drive, which can be done through a program called UNetbootin;
using a virtual machine.

The last method is only suitable for experienced users. To install, they will need to enter the following command in the console:

In this line, using the –m user command, you specify the amount of RAM that will be allocated for emulation.

However, regardless of the installation method, the device must have an Internet connection. This is necessary so that the operating system can independently download localization files and non-free packages.

The operating system installation process is as simple and straightforward as possible. Moreover, at the beginning of the process, the user can choose the language that is most convenient for him.

The only difficulty in the entire installation process is disk partitioning. Experts recommend performing this before starting to install the operating system, using specialized program Gparted, which is usually present on LiveCD. Or, during the installation process, select the “Manual partitioning” line. After this, the user will need to specify mount points.

Most in a simple way is the formation of free space by using the above program, after which a partition is created in it with file system depending on your own taste preferences. And during the installation process, you must specify the installation point “/” in the section. This pointer means that the OS will be installed in the root directory. Also, provided you have no more than 2 gigabytes of RAM, it is recommended to additionally create a partition called “swap”, which will be used for swapping.

Provided that the original installation parameters are preserved, the partition will be assigned the ext4 format. However, if you are using a “thick” virtual wallet in the section, it is recommended to install the Reiser4 format. This format is not initially included in the kernel; it will need to be installed additionally. This format will speed up the database synchronization process.

Experts also note that the Btfrs system format has a high level of performance. However, most people using this format consider it unfinished. The main rule when installing an OS is to create a backup of the most important files.

It is strongly recommended not to use the Wubi installer intended for installation with Windows OS, as it is focused on a full partition. This installer can only be used if the user has no skills in disk partitioning.

Once the installation process has been completed, the user will need to perform a reboot.

Mining setup

To set up mining, the user will need to install proprietary drivers for the video card. To do this, depending on the language of the operating system, you will need to write “dr” or “dr” in the search bar.

For installation, you must use only the stable version of the drivers, as experimental versions may cause crashes. Similar to the image in the picture, the user needs to select the version and press the “activate” button.

The next step is to launch a terminal emulator. To do this in search bar you must write the word “terminal”, or “terminal”, depending on the language used by the operating system.

Subsequently attaching the emulator to the left panel will ensure convenience in its further use.

After all the above steps have been completed, you need to update the system. To do this in command line you need to enter the following command:

You will also be required to provide the password that the user chose during the installation process. When you enter your password, symbols will be displayed instead of asterisks. If the password was entered correctly, the system will require confirmation of the process. To do this, the user will need to enter the command “y”.

The “dist” prefix present in the console indicates that the kernel also needs to be updated. Updating the system kernel, as well as installing drivers, requires a mandatory reboot of the device.

Once the reboot process is complete, the user will need to install a number of additional packages using the following command:

The last ones listed in this list packages provide the opportunity to complete the process of starting virtual currency mining in a more lightweight Openbox program, which allows the video card to produce the same amount of power as if it were working without a monitor. Also given environment allows you to work comfortably and even view various videos in FullHD format, without a significant reduction in power.

By default, the Linux OS has a file manager called Nautilus, which is recommended to be replaced with a more pleasant and lightweight program - “Thunar”. Despite its light weight, the program has a number of advantages.

The first advantage is the ability to open a terminal in a directory using the context menu. This allows you to significantly speed up the process of moving to the required directory.

The next, no less significant advantage of the program is the ability to assign an arbitrary command to open files of a specified type. Now, unfortunately, this function missing from the standard Nautilus file manager.

Nothing from the subversion and git packages will be installed, so you can completely forget about them. However, in case of emergency, these packages can still be installed. At the same time, installing openssh-server, recommended by some experts, is bad advice. First of all, this is due to the fact that few people will need remote access to the device, and this package will significantly reduce the level of security of the device. Setting up iptables will require a considerable amount of effort, since the Linux OS does not have even the most basic protection. However, if necessary, obtain remote access to the device, you should not limit yourself to installing the openssh package. For more reliable protection It is necessary to disable the password-based authorization process, since it is more efficient to use an asymmetric key pair with a passphrase.

WITH detailed instructions Settings for the key authorization process can be found on Habré. This information is contained in the article entitled “Hint for ssh users.”

To configure iptables with the “everything is denied” policy, you must enter the following commands at the command line:

The user will then need to copy to a file located in the etc directory called "rc.local". After this, you will need to enter the command “exit 0” anywhere before the line. The file will be opened using gedit.

If you need to open certain ports for incoming connections, you will need to uncomment the commented lines and list them in the OPEN_INPUT_TCP_PORTS variable, separated by commas.

Thus, access to the web server is carried out by opening port 80, while the ssh server is opened through a pre-installed port 22.

When using the bitcoin-qt program or a torrent client, then opening ports is optional action, however, it will provide the opportunity to significantly increase the number of connections.

The vim application is one of the most popular and is recommended for installation by most specialists.

If used in advance installed configurations and user learning of Mplayer hotkey assignments is one of the most best players video files.

A program called “enca”, used to identify encodings and recommended for installation in player configurations, automatically determines the subtitle encoding.

To complete the next setup step, you must official resources download:

AMD SDK 2.7;
pyopencl source files;
python-jsonrpc.

After the download process is completed, the contents of the archives must be unpacked. In this case, it is desirable that each archive be unpacked into a separate directory.

The unpacking process can be carried out using the GUI:

Or using the CLI:

The word "archive" used in this command is complete or in a relative way to the archive directory.

The user should also be familiar with the following symbols:

. – is the name of the current folder;
.. – name of the parent folder.

Ultimately, the path to the file will look something like this: ../../somedir/faultname.tgz

If the archive was previously placed by the user in the required directory, then you only need to specify the name of the archive.

AMD SDK Installation Process

To complete the installation process, you must use an account with root rights and run the following script: “Install-AMD-APP.sh”.

In this line, /path-to-directory$ is the exact address of the folder into which the archive was previously unpacked. The "~" sign indicates ownership root directory. For example, if the user unpacked the archive into the directory located at “~/Downloads/AMD_APP_SDK”, then he will need to launch the terminal and enter the following commands:

In addition, the user can perform this action with help file manager"Thunar". To do this he will need to call context menu by click right button mouse on any free space in the window:

The installation will be performed automatically in the folder located at /opt/AMDAPP.

In addition to executing the script using account With unlimited rights, there is no need to perform any other actions.

After completing all the above steps, the user will need to open the folder with the already unpacked pyopencl archive in any convenient way.

Installation and compilation of pyopencl is done from source code using the following command:

The following command can also be used as an alternative:

Depending on the bit depth of the operating system used, the user must compile:

Perform installation:

Go to the folder with the previously unpacked python-jsonrpc archive.

The installation process of python-jsonrpc is done using the following command:

If the user plans to use several video cards to mine virtual currency, then he must know that by default, video cards that do not have a connection to the monitor will not mine.

This problem It is possible to solve it in several ways: using software and using hardware. However, the second method is more common. To implement the second method, you must have at least one more monitor; this will be quite enough even if the user intends to use more than 2 video cards for mining. The option of simulating an additional monitor is also allowed.

To use all available video cards, you need to connect them to monitors. However, if there are no monitors, it is necessary to simulate their connection.

After the driver installation process is completed, AMD will appear among the system software Catalyst Control Center that needs to be launched.

It can also be launched using the command line using the command “gksudo avdcccle”.

Using it, you can launch other video cards for mining.

If all of the above actions are performed, virtual currency production will continue even after the monitor is disconnected from the video cards.

In this regard, it will be quite enough to use one monitor, connecting it alternately to each of the video cards. It is important to reboot the system before activating each card.

This way the user will activate all cards and will only be able to use the main monitor. The main disadvantage of this method is the need for an additional monitor.

After correctly completing all the above steps, the process of mining virtual currency in the OS will start.

If the user has neither stubs nor a second monitor, he will need to update the drivers for video cards. This method may help, but should only be done as a last resort.

Then the user will need to download any program for mining virtual currency and connect to the pool.

Many experts prefer a program called “Cgminer”. Setting up a cryptocurrency miner on Linux OS differs from setting it up on Windows only in the absence of the “.exe” extension and the command that runs the file.

In OS Windows startup miner will look like this:

And to run on Linux you will need to enter the command on the command line:

For the miner to launch successfully, the file must be identified as executable. If it has a different attribute, the launch will not be performed. This problem can be solved using the terminal. To do this you will need to enter:

Then check "x" for presence:

However, in case the user is in the folder with the "cgminer" file, he will need to replace "ls -1." to "ls -1".

Or, using the file manager options, change the file properties:

Many people prefer phoenix 1.7.5 because of its user-friendly interface. Therefore, we will consider the setup process using its example, despite the fact that cgminer provides more high level mining functionality.

In the configurations of the cgminer miner, the user can immediately specify the order of actions. It is recommended to create scripts intended for inclusion in the work of workers in a folder located at “~/bin/”. In this case, it is necessary that all of them have the executable attribute.

How to squeeze maximum power out of video cards

To optimize video cards, the user will need to change the graphical shell from Unity to Openbox. To perform this action, you will first need to log out of your account.

And then change the graphical shell to Openbox.

Initially, the Openbox graphical shell lacks all aids management. Essentially, this graphical shell is the basis for creating a user-friendly interface with taskbars, program icons and wallpapers. The main advantage of Openbox is the ability to create a custom interface.

Shell settings are located at "~/.config/openbox". A dot placed before the directory name allows you to make it hidden. By pressing the key combination “Ctrl” + “h”, the user can enable or disable reflection hidden files and catalogues.

For settings automatic start the user needs to set the command “autostart.sh”, to optimize the menu - “menu.xml”, and to activate hot keys and other useful options– “rc.xml”.

If a file is missing, you can easily create it yourself.

If the user made a mistake in the “menu.xml” code, then after saving its parameters, this file will not be displayed. However, you can make all the necessary changes to it using a text editor or special program called "obmenu".

For clear example consider the possibilities standard menu and improved:

You should also familiarize yourself with the points necessary to start mining virtual currency:

Their setup looks like this:

For most experienced users, the “autostart.sh” script looks like this:

The first line in this script was previously used to reflect the wallpaper, and in this moment it is commented out. If the user is interested in wallpaper, then, with the exception of uncommenting this line, he will need to additionally install the “feh” package and use the address of the location of the desired picture.

The second line in this script is used to set the keyboard settings in case it was previously configured incorrectly. The “Scrool lock” light on the keyboard serves as an indicator of the layout used.

The following line is used to launch the "tint2" panel.

The next part of the script is directly related to the virtual currency mining program amdconfig.

Before you start using it, you must run the following command:

Before overclocking the card, the user will have to write the following line on the command line:

Below are successful examples using various options:

“aticofig—odgt-adapter=all” – displays the temperature indicator of the cores;

“aticonfig —odgc —adapter=all” – value clock frequency cores;

“aticonfig —pplib-cmd “get fanspeed 0″” – displays the speed indicator of the cooler, and to change it, use the “.” command;

“aticonfig —pplib-cmd “set fanspeed 0 100″” – this way you can set the full operating power for the cooling system;

"export DISPLAY=:0.1; aticonfig --pplib-cmd “get fanspeed 0″” – determines the rotation speed of the cooling fan on the second video card. A unit in the code can be replaced by a two or a three, depending on the number of video cards installed for mining.

“aticonfig —od-setclocks=900,1000 —adapter=all” is a command for the memory frequency with a value of 900 and 1000 MHz, respectively.
