@cecil said in RRF3 several issues:
You mean something like changing M558 parameters on the fly during homing? That can work! Thanks
Exactly so. For info, this is an extract from one of my homing macros...........
;change to faster probing speed
M558 F450
G30 ; FAST home Z using values from G31
G91 ;relative
G1 Z5 F300 ; lower bed 5mm
G90 ;absolute
;change back to slower probing speed
M558 F180
G30 ; SLOW home Z
