Setting Limit Switches on a K40 Laser Machine
First I'm very new to K40 repairs, so please try not to be too technical, so I understand.
I recently purchased a new XY Axis for my K40 and installed it. I hooked up the X (right to left) limit switch using the wires old limit switch wires located by the step motor on the right hand side.
Question is how do I hook up the Y (front to back) axis limit switch? I didn't see any other wires that would connect to that switch.
Any assistance would be greatly appreciated.

Suggestions to what might be causing it?
