Every now and then Stepper_z1 doesn't enable properly.
As the title says. From time to time my printer doesn't enable z1 properly when it should be. Instead making an awful noise and not moving(a lot) while homing.
This issue will persist between turning the printer off and on again but can be resolved(semi permanently) by enabling the z steppers manually and then homing. Next time it's turned on it will work flawlessly again for weeks/months.
Anybody have an idea of what's causing this? Should I just enable the z steppers when turning the printer on and forget the issue existed?

I'd say first check your wiring.
@VisualTech48 you were right https://i.imgur.com/gFEKqjE.jpg
in my defense, at the time it looked fine and kept working until yesterday
@Maarten Glad you got it. Wiring is most common with these type of issues.
Thanks dude, at the time I looked at it, nothing looked wrong and the cables all felt the same, so I was headstrong and kept using it
yesterday I got a Z1 overheat warning and saw this when investigating
@Maarten When you redo that connector make sure that the rear part of your crimps properly clamps down on the wire insulation, you should be able to give your crimp connections a good pull without them coming loose. Starting at section 10 this guide has some good pictures for what you should be looking out for: https://www.instructables.com/Make-a-Good-Dupont-Pin-Crimp-EVERY-TIME/. It is for Dupont connectors, but those are quite similar to the WR-WTB connector son the Duet boards.
Also while you are at it I would suggest you make sure the screw terminals on the duet and your power supply haven´t come loose aswell, I was recently quite surprised to find out how much the vibrations in a printer can loosen them.

Make a Good Dupont Pin-Crimp EVERY TIME!: Anyone working with an Arduino, Raspberry PI, Beagle Bone, or any other multi-circuit-board project has become familiar with .025 X .025 in, square post pins and their mating connectors. The male pins are usually mounted to the circuit board with bo…
Personally I would even say that the example for a good crimp in that guide did not get quite enough insulation, I would want my crimps to look like this:
thanks for the info! I did crimp all the other connectors correctly but I think this one must have snuck through my quality assurance. Calling it a case of the mondays
Good tip on the screw terminals, I'll check those when I redo the crimp later tonight
