-Yes, a PC is required to run the myCNC software, which will be used to control the myCNC board. You can use a full industrial PC (such as the one provided in some controller kits in our Shop), or you can use a small single board computer, such as a Raspberry Pi, an Odroid or a TinkerBoard. The links to download the myCNC software are available at our [[https://​www.pv-automation.com/​download|Downloads]] page. +Yes, a PC is required to run the myCNC software, which will be used to control the myCNC board.

-++++ Why is there no connection between my computer and the myCNC controller? |+++++ Is a myCNC controller ​required to use the myCNC software? |
  
-If there doesn'​t seem to be any connection between ​the controller and the computer running the myCNC software ​after the computer ​and the controller have been connected by an Ethernet cablecheck that the controller IP address has been specified ​correctly ​in the Settings > Config > Network ​Controller IP address field. If that address ​is specified correctlygo through ​the No Connection troubleshooting manuals for your system[[troubleshooting:no_connection|No Connection between myCNC controller and a Host computer]] ​these manuals will indicate how to set static IP address on your computer to be in the same subnetwork as your controller. Note that if your WiFi is in the same subnetworkit might lead to issues with computer-controller communication - try disabling ​the WiFi if the issues persist+Yes, a myCNC controller is needed ​to use most of the functions of the myCNC software. The main software itself is free and can be downloaded from our [[https://​www.pv-automation.com/​download|Downloads]] page. Please note that certain specialized software add-ons (such as G-code correction via DXF import with markers) are available as separate licenses which do have to be purchased in addition to the controller
 + 
 +The software can be downloaded ​and tested in Simulation mode, designed to help the user get a feel for the software layout and functions. However, the Simulation mode is highly restrictive,​ with most features not accessible without a myCNC controller.

 +====Software Setup==== 
 + 
 + 
 +++++ What are the login credentials for a computer running ​a custom Linux build? | 
 + 
 +The login credentials for all Linux computers using the myCNC Ubuntu MATE installation are the following:​ 
 + 
 +Login: **mycnc** 
 + 
 +Password: **operator** 
 + 
 +++++ 
 + 
 +++++ How do I navigate ​the myCNC software? | 
 + 
 +A short introduction to myCNC software is available here: 
 + 
 +{{youtube>​fLAJ_VZs-fM?​large}} 
 + 
 +If you would like more information about all the particular buttons ​and on-screen elements in a particular myCNC profileplease consult ​the [[mycnc:​mycnc_screen|MyCNC Screen manual]]. 
 + 
 +++++ 
 + 
 +++++ How to load G-code or DXF files into the software? | 
 + 
 +{{youtube>​RGNR-iafcaI?​large}} 
 + 
 +The files that you are attempting to load must be located in folders that are specified in the **Settings > Config > Preferences ​Common** fields for **NC code folders**. If a folder ​that you would like to load your files from is missingadd it on a new line and press the Save Configuration button: 
 + 
 +{{::forum-mar2020-002-code-folders.png}} 
 + 
 +If folder is not listed ​in the NC code folders list (or is not within one of the folders listed)you will not be able to open files from it  within the myCNC application.  
 + 
 +The following standard folders are used on Linux (Ubuntu MATE) installations:​ 
 + 
 +''​~/​DNC/''​ 
 + 
 +''​~/​Desktop/​G-codes/''​ 
 + 
 +The ''​~''​ symbol allows you to not write out the whole /​home/​USERNAME/​DNC line, however ​the full filepath can also be used.  
 + 
 +The following standard folders are used on Windows installations:​ 
 + 
 +''​C:​\DNC''​ 
 + 
 +''​C:​\DNC\LIBS''​ 
 + 
 +After you have listed the folders that you would like to have access to, you can open files using the **Open G-code** and **Open DXF** buttons from the main software screen:  
 + 
 +{{::​faq-qs-012-open-files.png}}

 If updating manually, many users also prefer to keep their PLC folder intact to make sure any changes unique to their setups do not get overwritten by the default configuration. ​ If updating manually, many users also prefer to keep their PLC folder intact to make sure any changes unique to their setups do not get overwritten by the default configuration. ​

 +++++ How to switch the profile / technology? |
 +
 +In order to switch the current technology / profile within the software (for example, to switch from the Mill profile to a Plasma profile, or from a Plasma profile to Tangential Cutting):
 +
 +  * Go into Settings > Info
 +  * In the right panel, select the profile you'd like to switch to (for example, X1366P)
 +  * Click the Save Profile button
 +  * Reload the application
 +
 +{{::​forum-feb2020-014-profile-switch.png}}
 +
 +The myCNC software should now switch to the chosen technology profile. ​

-++++ Why is the machine not moving despite the on-screen coordinates changing? |+++++ How to set up homing? |
  
-If after the motors have been connected, the machine isn't moving despite the on-screen coordinates changing while pressing the jog keys, the pulse width might be set up incorrectly,​ causing the motors to not register the signals sent from the controller. ​The exact pulse width is different for every motor, so it is not possible ​to preset a default configuration which will suit every machine. Check the guide on setting up the pulse width in this manual: [[mycnc:​mycnc_pulse_width_setup|MyCNC Pulse Width Setup]]+The following video is available ​to aid the user with the homing procedure setup.
  
-Typically, if using a stepper motor, a higher setting number than the default should be chosen in order to allow the machine to register the pulses sent to it. +{{youtube>​WDXHJ6PYuq0?​large}}
  
-NOTEThe first value in the Pulse Width field in the myCNC settings refers to the first four movement directions for the controller (for example, X+, X-, Y+ and Y-), while the second value refers to the last two movement directions (for example, Z+ and Z-). Typically, these fields should be set to the same value, however they can be different if different drivers are used on the last two axes (motors 5 and 6) as compared to motors 1 through 4. +A full manual is available here[[quickstart:​mycnc-quick-start:​homing_setup|Homing Procedure Setup]]

 +++++ How does the Run from Here procedure work? |
 +
 +{{youtube>​86YEjR1CJlw?​large}}
 +
 +In an event of an emergency stop or failure of a mill machine running a program file, it is often useful to be able to open the file back up afterwards and be able to continue from the middle of the program without having to go through all the steps again. This is often complicated by the fact that a large program file consists of many lines of code, making it difficult to easily navigate to the place where the cutting process stopped initially. In order to facilitate finding this spot, the Run from Here process is put in place in myCNC software. ​
 +
 +The Run from Here method is described in the following section of the myCNC Screen manual: [[http://​docs.pv-automation.com/​mycnc/​mycnc_setup_examples/​four_axes_mill#​run_from_here|manual link]]

 +++++ Why is there no connection between my computer and the myCNC controller? |
 +
 +If there doesn'​t seem to be any connection between the controller and the computer running the myCNC software after the computer and the controller have been connected by an Ethernet cable, check that the controller IP address has been specified correctly in the Settings > Config > Network > Controller IP address field. If that address is specified correctly, go through the No Connection troubleshooting manuals for your system: [[troubleshooting:​no_connection|No Connection between myCNC controller and a Host computer]] - these manuals will indicate how to set a static IP address on your computer to be in the same subnetwork as your controller. Note that if your WiFi is in the same subnetwork, it might lead to issues with computer-controller communication - try disabling the WiFi if the issues persist. ​
