Z Homing, nozzle doesnt reach bed

Hi there,

as far as I know, Repetier forbids negative Z offsets.
The closest I can get the nozzle to the bed is about 1mm, I cant unscrew the z-endstop adjustment screw any further.
As I dont have a Zmax endstop, I also cant home to Zmax.
Is there any way I can get the nozzle closer to the bed softwarewise?



  • Yes, but it is not nice as you can not do the official and correct solution.
    Make sure firmware is compiled with ALWAYS_CHECK_ENDSTOPS 0
    G1 S1
    G92 Z1

    adjust G92 to what ever height you have after homing. G1 S1 disables coordinate check. That should allow you to move to Z=0.
