@MAHLE_RW said in Configuring Z-Axis height with BL Touch:

M425 Z0,05 S10 ; Z Umkehrspiel ausgleichen (Hepp)

and

G31 X0 Y0 Z3,7 ; set Z probe trigger value, offset and trigger height

Don't use commas for decimal points, use a full stop. It will ignore everything after the comma. eg:

G31 P500 X20 Y0 Z2,9 G31 Z probe 0: current reading 0, threshold 500, trigger height 2.000, offsets X20.0 Y0.0

Setting G31 to Z2,9 results in trigger height of 2.000, not 2.900.
