In case you are having issues after updating to a new software version, or would simply rather use an older version, you can use the following instructions:

• Head into the folder containing the myCNC application (/home/opt/myCNC on Ubuntu machines)
• Select the folder in which the launch file for the myCNC application is located (ubuntu18_64 in this example)

• Delete the file named myCNC (this is your current program version)

• Locate the backup file with the date to which you would prefer to roll back

• Rename that file to myCNC
• Launch/relaunch the myCNC application

The program should now be using the backup version.
