      Hi All... I'm working through getting my printer all setup and have started to run through my tweaks.

      I'm now trying to level my bed.
      I've got a EZABL Pro, it's setup, it's working, and I've configured it as per the TH3D site.
      I then ran the prob mesh to set my bed mesh values

      Once I tried to run a test print the nozzle is on the bed and when I try to babystep it down, the nozzle doesn't move. I can see the z-offset value changin in DWC, I went all the way to 15mm but the nozzle did not move.

      I remember reading a thread where some gcode would prevent babystepping, but I can't find that and forget which command it was.

      Would love some insight and help! For some reason I'm drawn to the M420 command, but can't be sure.

        @infidelprops said in Babystepping - not stepping:

        M208 X0 Y0 Z0 S1 ; set axis minima

        your printer won't go below your M208 minima, in this case that is 0mm
        M208 X0 Y0 Z0 S1 ; set axis minima
        you need to make M208 for Z a negative value to go any further
