Noob here! Having problems with z axis on Ender 3.
-
My nozzle is about half an inch above the bed when i auto home. I have tried moving the z axis but it will only raise and not lower. Any help is appreciated.
-
@a2iink Please check whether the limit switch is damaged and the wiring is loose
-
@a2iink also consider breaking off the little tab that keeps the Z endstop above the platform. I just did this yesterday, a lot of people do this.
-
@a2iink probably, your Z endstop is too high.

@a2iink wich is your machine? Could you send some photos?
