Home Z with BLTouch

brasse

Hey, im trying to edit the homez.g to allow my Z to safely home. The probe is positioned outside the bed, so when i try to home the probe does not hit anything.

Ive tried this setup, but it wont move X/Y-axis before running the G30 command.
G90 ; Make sure we are in absolute mode
G1 S1 X100 Y100 F1800; move to middle of bed
G30 ; Do a single probe to home our Z axis
G1 Z10 F6000 ; Rapidly move the Z axis to Z=10.

Whats is the recommended way to set up the homez.g when having the probe outside the bed when X/Y is homed?

Best Regards // Lars

Take out the S1

This is mine:

You can also remove 'H0' , is useless.
M558 Fxxx is used to reduce speed

If your probe goes outside the bed maybe you have done some mistakes during configuration (like me ).
To solve I've configured (via RRF tool) the firmware and upload it overwriting the old files.
(Probably your mistake is in probe's offset , in my case was only a minus before the number !!)
