[SOLVED]Z height and M208 from v1 RRF web config
bearer last edited by bearer
Been scratching my head how to get my Z axis to home at Z=120.
I used v1 RRP configurator as I had issues with the new one and PT100 inputs.
I enter No Z probe, Zmin 0, Zmax 120. Limit switch at Zmax
; Axis Limits M208 X0 Y0 Z0 S1 ; Set axis minima M208 X123 Y128 Z120 S0 ; Set axis maxima ; Endstops M574 X1 Y1 S1 ; Set active high endstops ; Z-Probe M558 P0 H5 F120 T6000 ; Disable Z probe but set dive height, probe speed and travel speed M557 X0:120 Y15:105 S30 ; Define mesh grid
Is the generated config, but if I run
G28machine correctly moves bed down and hits the switch, but the axis is set to Z=0 and not Z=120.
After a heavy detour with adding
G92to homeall.g I changed the
M208by hand to
M208 X123 Y128 Z120:0 S0and that seems to get me the desired result.
Is there a way to input this into the RRF and produce the desired output, so the config.json file is valid for future changes?

Seems you didnt configure endstop for Z axis. So you should add:
M574 Z2 Sx - where x is 0 or 1 depends your switch type. Z2 means endstop on high end of Z axis.

I did see that, but between having clicked the relevant buttons in RRF and the board actually responding to the Z switch I presumed magic was involved.
M574 Z2 S1and leaving
M208as it was originally certainly fixed it, homes correctly and sets the Z height as I want.
Thank you for your help!
