Duel End Stops stopped working

Mostly Printed CNC - MPCNC Troubleshooting

Been using this beauty for a few months with no issues but kind of hit a brick wall. maybe someone has seen this issue in the video. Have a feeling its something simple, but still doing my head in.

  1. End stop blocks are equal distance on the x axis (measure with calliper)
  2. End stops work when i press my press home and trigger my hand. Using V1 stock firmware on SKR Pro board
  3. If the steppers are off and i move it around by hand its pretty square.
  4. When i home xy, y is fine but x jams and it wont move the extra few mms to trigger the end stop

Was working fine. Cleaned up the cables and then stopped working. Thought i ruined something but triggering the end stop by hand seems to work fine

Is it possible you have the endstops swapped? X2 endstop is connected to the X1 port?

Yes that was it. No idea how i switched the cables around. I guess i got so flustered i couldn’t see it.

Thank you
