Z-Endstop failure

Snapmaker 2.0
1

Hey guys,

today i encountered a problem with my z-axis max-endstop on my A150 with new rails.When homing, the printhead went up and didn’t stop. The printer tried to go up even further but couldn’t and the motor kept skipping loudly. I suppose the endstop is broken or loose but how can I fix it? Is it save to open the Z-Axis to get to the endstop and if so, is there anything to be careful of? I’m pretty familiar with the mechanics and technics in a normal 3D-printer with open axis, but not with closed axis like snapmaker.

I hope you can help me :slight_smile:

Simply screw it up, the stepper motor is on the other side so no worry.
There is surely a thread about in the forum but it is so easy, you will see.

Edit @blaba, here you go:

Thank you, that looks promising.

Edit: It’s a little bit tedious to loosen the screws, but i managed to change the endstop. The black cover of the switch broke, so the little plastic switch-cap was gone. Now it works like a charm again :slight_smile: Thank you!
