@bearer Tried that - gave me an endstop configuration error

@bearer nice idea - especially if the height variantion is potentially higher.
still I’d prefer a solution without loop but I wasn’t able to find a solution that also terminates the X move when the Z endstop is triggered

A very crude solution that works as proof of concept:

M561                    ; clear any bed transform

; If the printer hasn't been homed, home it
if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed
  G28

M574 Z1 S1 P"^!zprobe.in"        ; configure active-low endstop for low end on Z via pin probe.in

G90 							; absolute positioning
G1 Z12 F1200

G91								; use relative positioning

while iterations < 100
	G1 H1 X1 Z-0.2 F120
	if sensors.endstops[2].triggered
		G92 Z10                                 ; height of touch plate
		break

G1 Z25 F1200
G90 							; absolute positioning

; restore endstops
M574 Z2 S1 P"zstop"                            ; configure active-high endstop for high end on Z via pin zstop

@Phaedrux I hoped there is a way without modifying the firmware.
The touch area would be mounted to the bed and ideally the head moves constantly in a small circle while descending in Z.

It surely is possible but way more complicated.

Hi!

I need to change nozzles quite often so I need a fast way to correct my Z height.
A test setup using an aluminum block to short the nozzle against works promising but the nozzle has to be extremely clean to get it accurate. An easy fix would be to move the head while probing - I verified this moving the aluminum block by hand (which I do not really enjoy because of high chamber temperatures (> 100°C).

So is there a possibility to do a probing move with X/Y components?

Thx,
