  • The limit switch is correctly adjusted on the machine

Follow the Troubleshooting Steps to determine the cause of the shorted limit switch circuit.

Before You Begin

If you haven't yet done so:

  1. Open the electrical cabinet door.

    WARNING! Electrocution Hazard: When servicing the machine from inside the electrical cabinet, always use caution. Points in the electrical cabinet have high voltages that can electrocute or shock you. Even after you've powered off the machine, electronic devices in the electrical cabinet may retain dangerous electrical voltages. Only qualified electrical machinery technicians should perform maintenance or troubleshooting procedures inside the electrical cabinet while power is still on.

  2. Locate the Machine Control Board.

Troubleshooting Steps

  1. Locate and remove wire J2-1. Make sure that the wire does not touch any metal or other wires in the electrical cabinet.

  2. From the PathPilot® interface, on the Status tab, locate the X Limit light.

Is the X Limit light on?

  • Yes: You must replace wire J2-1 on the Machine Control Board, then go to Remove Wire From the X-Axis Limit Switch Box.
  • No: This means that the Machine Control Board is defective and must be replaced. You must replace wire on J2-1 on the Machine Control Board. Tormach Technical Support for guidance on how to proceed.
