@pixelpieper do you share your cad files somewhere?

Ended up with the following macros:

var paperTest  = 1.1

M290 R0 S0			; babystepping = 0
G29 S2				; turn off bedmesh
M98 P"/macros/Drive/home_if_not.g"	; home if needed
M98 P"/macros/Printing/nozzle_brush.g"
G28 Z				; home Z
	
G1 X245 Y300 F99999	; go to probe point

var lastStopHeight = -1
while iterations < 2 || abs(sensors.probes[0].lastStopHeight - var.lastStopHeight) > 0.005
	set var.lastStopHeight = sensors.probes[0].lastStopHeight
	G30 S-1				; probe without setting
	G1 Z5 F99999


var newTriggerHeight = var.lastStopHeight + var.paperTest
var deltaTriggerHeight = var.newTriggerHeight - sensors.probes[0].triggerHeight
echo "Trigger Height Old, New, Delta: " ^ sensors.probes[0].triggerHeight ^ ", " ^ var.newTriggerHeight ^ ", " ^ var.deltaTriggerHeight

G30    ; probe

@T3P3Tony yep, voron 2.4 touches z-endstop with a nozzle tip (by default), not with a gantry

Hi all!

I'm setting up my voron 2.4r2 and it looks like I'm "implementing my own bicycle". I'm sure there is a solution in RRF.

What I'm trying to achieve is to automatically calibrate offset of hot-end using both z-endstop and z-probe.

There are static distances that aren't changed when hot-end is changed:

• z-endstop vs bed
• bed vs z-probe (inductive probe trigger height)
• z-probe vs head (it's mounted on the head)

There is a dynamic distance "hot-end vs head" that changes when hot-end is changed. But since hot-end presses directly to z-endstop and also we can calculate "z-endstop vs head" distance via that chain of dependencies, so there is no need in paper-test after hot-end changes, since we can calculate it.

Initially I set up G31 Z* with a paper-test. Now I'm simulating hot-end length change and trying to re-tune offset automatically.

Currently I'm playing with G30 S-* command parameters but can't find a solution for the issue. They change not what I need to change, do they?

Looks like I'm missing something trivial?
