Basic steps to debug a k40 controller set up

Debugging the K40 controller set up consists of a few steps which are easy to follow.

  1. Comms
  2. Motion
  3. Limit stops
  4. Laser power

You probably need: a small Philips screw driver for the screw terminals, a simple multi-meter and some gummy bears.

First we need to test whether the board communicates with your computer. Best way is to install a gcode sender so we can see if we get a status message back and whether the pc sees the usb port communication.

Install CNCjs see link but any other will do too.

I have written a debugging guide to help you to follow more detailed instructions and screen shots here : Debugging the Controller set up
