Background

The console is an all-in-on controller with computer, touch screen, and some additional knobs. Its job is to run PathPilot and control your CNC machine. While its appearance is different from our other controllers, it functions the same: it controls your machine and provides you with a friendly user interface.

Tools

• Digital multimeter

• Small flat-bladed screwdriver

• Metric hex wench set

• Phillips screwdriver

Adjust the Touch Screen Sensitivity

Reason: The touch screen doesn’t respond to touch inputs on all or part of the screen’s surface.

Before you begin, make sure the plastic protective sheet is removed from your screen.

The touch screen is a resistive type to prevent accidental triggering from drops of coolant on the screen. The resistive touch screen may need its sensitivity adjusted when used in a shop space with very high or low humidity.

1. Verify that you have PathPilot v2.4.4 or higher installed on your controller.

2. From the PathPilot interface, in the MDI Line DRO field, type Admin Touchscreen Sensitivity 1000 and press Enter. You can use a value between 1 and 2047, but 1000 is generally sufficient for most shop spaces.

Reason: The Cycle Start or Feed Hold buttons don't are disconnected.

...

1. Remove the rear panel of the console.

2. Examine the wire inputs to connector J13 on the control board. If any wires are loose, tighten the screw terminals.

3. Using a continuity tester, measure the resistance between terminals 1 and 2 when Feed Hold is pressed and terminals 3 and 4 when Cycle Start is pressed.

   1. If there's continuity at the terminals on the control board and the buttons still don't work, examine the USB cable to the control board.

   2. If there's not continuity at the terminals when the buttons are pressed, remove the lower rear panel of the console and examine the screw terminals on the rear of the buttons themselves.

4. If you have tested all terminals and the buttons still don't have continuity when pressed, replace the buttons:

   1. Feed Hold Button (PN 37363)

   2. Cycle Start Button (PN 37362)
