@fcwilt said in Why first move of tue bed leveling is going up?:
Now change the H2 parameter in the G31 command to H5.
I don't find where is this command with H2.
It's here?
;;;;;;;;;; BLTouch ;;;;;;;;;;
M950 S0 C"20.io0.out" ; Create a servo pin on io0 (toolboard 1LC)
M558 P9 C"20.io0.in" H5 F240 T10800 A5 ; set Z probe type to unmodulated and the dive height + speeds
G31 P25 X-28.00 Y-13.00 Z3.700 ; set Z probe trigger value, offset and trigger height, more Z means closer to the bed
But there is no H2 parameter in the G31 command.
