I have a gantry machine with two separate z motors, each with their own endstop. The other day I homed my machine and the left side was significantly higher than the right.

Thinking that my machine was down and that I’d at least have to get a new endstop or something, I decided to go get some coffee and think it over.

When I got back and investigated further, I realized that the left side had come down on top of the cable that supplies power to the motor. A quick zip tie to make sure it stayed out of the way and a rehome and I was in business.

Sometimes it’s the simple things.
