Permantly save Z-Probe Offset after Z-Calibration via G30 S-3

wieman01

Hello,

After completing the z-calibration procedure I typically open "config.g" and manually adjust the z-offset by using G31.

config.g:

; BL Touch
M950 S0 C"duex.pwm5"												
M558 P9 C"^zprobe.in" H5 F150 T6000									
G31 P25 X0 Y-36 Z1.95

z-calibration (part 1):

G28
M561
G1 F3000 X240 Y160 Z20	
M564 S0

z-calibration (part 2):

G92 Z0
G1 Z5
G30 S-3
M500

I was hoping M500 would save the setting in "config-override.g", but it does not.

Is there any way I can make this a permanent setting (i.e. even after restarting the machine) once I have run the script?

Thank you.

@wieman01 you want M500 P31

Oh, gosh, can it be that simple?! Thank you, my friend, that worked like a charm. All good now, the G31 parameter is safely stored in "config-override.g".

How would that work with several tools? Do I add the toolnumber?

@o_lampe you want M500 P10 to save the tool offsets.
at least with my toolchanger that i used to run (and its the same with the E3D toolchanger) all the tools were relative to the z probe. So the z probe had no offsets and each tool was offset from that using G10
