Second Pass on Homing Z with Bl-Touch
-
Hey everybody,
I was working on my G-Code the other day and I was wondering if there is a way to to use a second, slower pass on Z homing with the Bl-Touch? I tried G1 S1 Z-300 F100 but my printer is ignoring these z homing commands and will only z home with G30.
So is it possible to something like:
G1 S1 Z-400 F1800 ; move Z down stopping at the endstop
G1 S2 Z1 F3000 ; go back a mm
G1 S1 Z-400 F100 ; move slowly to Z axis endstop once more (second pass)... but with G30, or reduce the speed of G30 homing in general?
Thanks a lot!

Think you are asking the same thing as me in the dive thread

You are right, I was under the impression you were asking for a way, other than G30. Thanks for the clarification, this post can be deleted.

@philippth sure you can.
; Z homing section follows
;
G90 ; absolute positioning
G1 X190 Y90 F4000 ; Move x and Y axis over to bed center so probe is on top of bed; Set lower speeds for homing
M566 Z5 ; Set maximum instantaneous speed changes (mm/min) (Jerk)
M203 Z350 ; Set maximum speeds (mm/min)
M201 Z100 ; Set maximum accelerations (mm/s^2); Probe the bed
;
M558 A1 F350 ; Set single probing at faster feed rate
G30 ; Do a single probe to home our Z axis
M558 A10 F100 ; Set tripple probing at slower feed rate
G30 ; Probe again to get a more accurate position; Set normal speeds again
M566 Z60 ; Set maximum instantaneous speed changes (mm/min) (Jerk)
M203 Z600 ; Set maximum speeds (mm/min)
M201 Z600 ; Set maximum accelerations (mm/s^2)
