How to change a limit switch

This video is about changing the limit switch on the J750. If your laser is not homing properly, banging into the home position, you likely have a bad limit switch.

To test the limit switch, pass a metal object over the top of the switch. If it lights up, it's good; if it doesn't, it needs replacing.

Included in your toolbox, you'll find a replacement switch. Follow the steps in this video to change it.
