-++++ Why is there no connection between my computer and the myCNC controller? |+====Software Setup====
  
-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 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 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+++++ How do I navigate the myCNC software? |

-++++ 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 to remove the homing dialog that keeps popping up when starting the program? | 
- 
-The homing dialog is done through the HOMING_HANDLER Software PLC. If you would like to disable it, add a line saying exit(99); near the start of the code like so:  
- 
-{{::faq-qs-homing-handler-002.png}} 
- 
-This will force the handler to exit before showing the popup. In order to bring the popup up again, simply delete the exit(99); line, or put two forward slashes in front of it, like so: 
- 
-<code> //exit(99); </code>

- 
-{{::faq-qs-004-sofware-plc.png}} 
- 
-The ''portset'' command activates a certain port (for example, //portset(3)// will activate output #3), while the ''portclr'' command clears the specified port (//portclr(3)// will turn off output #3). In order to disable these commands, either delete them from the relevant Software PLCs, or comment them out by putting two forward slashes in front of the commands. Don't forget to press the Save All and Build All buttons to make sure that the changes take effect.

-ClearPath drivers will not out of the box unless using the line driver to 5V converters. Here is the official explanation from the ClearPath website as to why the ClearPath drivers are not directly compatible: 
- 
-{{::faq-qs-005-clearpath.png}}

-Effectively, a converter board is necessary to create a steady 5V signal which the ClearPath driver will be able to register. These line driver to 5V converter boards are available as part of certain kits on the myCNC [[https://shop.pv-automation.com/|Online Shop]].

 +++++ How does the Run from Here procedure work? |
 +
 +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]]
