Background

The controller is the computer that runs PathPilot and controls your CNC machine. While the controller itself could be different (a tower, a brix, rev c, rev d, an operator console, etc.), they perform the same function in controlling your machine and providing you with a friendly user interface.

The operator console is an all-in-one system and might require different troubleshooting. For operator console troubleshooting steps, go to Operator Console Won't Work .

Start the controller with only the monitor connected

Reason: There is a USB issue.

  1. Power down you machine and remove everything from your controller except power, machine communication, and the monitor.

  2. Power back up.

  3. Does the controller boot farther into PathPilot?

    1. If yes, attach one USB at a time until you find the problematic USB connection.

    2. If no, check time and date in BIOS.

      1. To get into BIOS, restart computer and rapidly press F2 or F10 (tower controllers), or Del (for brix, rev c, etc.). If your date and time are accurate, and you still are having issues, restore to factory settings.
