I have an Elegoo 20 watt Phecda diode laser. and all of a sudden it will not home in the X. I have limit switches in all 4 corners. All 4 switches light up red when I manually touch them. The wires are good & connectors, nothing is loose. When homing Y does fine X will hit the limit switch, it turns red but still tries to keep going beyond hitting the hard stop which at that point I have to power off. Any ideas on what setting this could be? Or where I should be looking to resolve this issue? Any help would be great as I am new to laser engraving. Thank you.
Sounds like the signal is not coming to the board. The power wires might be ok (LED lighting up) but the signal wire is not. Check with the question mark command if the switches are recognized:
What does the screenshot tell us? What did you do in that moment?
When I hold the limit switch down in the Y it shows PY When I hold down the switch in the X it just show P when I type ? in command
How do I know if it is the wire or the switch in the X?
after removing the limit switch for the X axis I did discover a broken wire
