topic_solved Assistance with G30 speed
I need a bit of assistance on the initial G30 speed when finding Z=0. What is the best way to speed it up?
Here is what I've been messing with. It drops the gantry at 1200mm/m on the first pass, then slows it back down to 180mm/m for the final pass before independent z-stepper leveling.
However, something's wrong with this as Z is always 2mm too high afterwards.. I haven't figured that out yet.
Is there a better way than M558? I don't see where G30 supports a speed parameter. Could "M558 F1200" be called and all other parameters remain unchanged?
M558 K0 P9 C"20.io0.in" H2 F1200 T12000 A10 R0.1 S0.01 G92 Z333 G30 Z-99999 M558 K0 P9 C"20.io0.in" H2 F180 T12000 A20 R0.1 S0.01 M561 G30 Z-99999 G30 P0 X0 Y260 Z-99999 G30 P1 X264.80 Y260 Z-99999 S2

have you done this?

yes that should work
@Veti yes - I have all that sorted out.. just working on the startup routine when the system has no idea at what height Z is at.
I'll give the shortened M558 command a try now. Thanks for the pointer!

@Veti this worked.. thanks again! I figured I better ask instead of goofing up and ramming my nozzle through the bed.. lol
M558 F600 A1 ; probe once fast
M558 F60 A10 ; probe at least two times slow
