I do not think your ideas help. I tested them but they did not improve anything...
but I found the mistake!
You know....in programming you are often start counting with 0....not with 1. So my x Stepper is not P0.1 but P0.0....
Oh my gosh...works now.
Sorry for the late response.
I tested the code and it works absolutley flawless!
Thank you for your help!
up!
I really want this feature - or a workaround - as well 
Hey guys,
at the moment I am working on a dual extruder tool together with @CR3D . The first prototype of the tool is working right now - the tool is comparable to a Startasys or Ultimaker 3 Nozzle-Lifting assembly but the actuation is done by a servo. At the moment I am stresstesting and performing little improvements.
I want to use / built a firmware-integrated nozzle-offset-routine for both hotends - in this I want to calibrate the x, y and z offset of both nozzles.
To calibrate the offset of both nozzles I want to use a routine similar to the one by BCN3D and Craftbot.
At first I want to move the nozzle - close to the bed using a PanelDue and/or webInterface.
After that is done for both tools a simple z-offset test print (i.e. 20x20mm 1-layer square) shall be printed.
Afterwards the user shall be promted if the z offset is ok. If yes: the routine continous. If no: the routine goes back to z-offset adjustment.
The same is done for x-y-offest - just with using "line" extursions like the ones on the picutre:
I tried to built a flow chart of the things I want to do:
Writing the gcode and doing basic configuration is not a problem for me.
My main questions are:
Have a nice day,

Maybe some of you have seen my post of trying to built a calibration routine for the CR3D Idex machines.
https://forum.duet3d.com/topic/21803/calibration-routine-for-dual-extruder-printers
This thread did not get much tracktion...probably due to the kind of complex nature of such a routine. So I'll try to break down the problem into smaller chunks.
The "newest" problem is the user-interaction.
After completing the z-calibration the user should be asked, if he is satisfied with the results. Otherwise it should be repeated.
; start z-calibration routine
while z_satisfied = false
M291 P"Put a piece of Paper on the built plate" R"Calibration of z-Position" S2
T1
M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 1" S3 X0 Y0 Z1
G10 P1 Z{-axes[3].position} ; set z-offset of Tool1 to value from last calibration
M500 P10 ; safe Tool1 offset
G1 Z5
T2
M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 2" S3 X0 Y0 Z1
G10 P2 Z{-axes[3].position} ; set z-offset of Tool2 to value from last calibration
M500 P10 ; safe Tool2 offset
G1 Z5
M291 P"Remove Piece of Paper" R"Calibration of z-Position" S2
; start test print for z-calibration
;M98 P"z_test_print.g" ; Print z-calibration lines
; ask user if he is satisfied
M291 P"Are you satisfied with the z-calibration results or should this step be repeated" R"Calibration of z-Position" S2
; If M291_input = yes
; z_satisfied = true
;else
; z_satisfied = false
Is it possible to get a "feedback" and or yes/no-buttons with M291 or is there any other way of "user-interaction"?

Thanks for your response!
For the time beeing I'll try some drivers I have laying around (without SPI) to just test it....maybe later on I'll return to the SPI-question. Mostly because I don't know how to compile duet firmware on my own and have to read that up
Have a nice day,
Max
EDIT:
I have Firmware Version 1.17 on my PanelDue and will Upgrade to the latest. The macros are only supported from 1.20 in.
