      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.

      Is there any way to store the tool offsets after doing
      a) z-offset-calibration
      b) x-y-offset-clibration

      M500 does not safe it. I tried something like that (writing to a file on the sd-card).

      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
      M28 tool1offset_z.g 			; generate file for z-offset Tool1
      G10 P1 Z{-axes[3].position}		; set z-offset of Tool1 to value from last calibration
      M29
      

      There are 2. Problems with this:

      1. the file "appears" in the print-files folder which is not really nice for our customers.
      2. It writes
      G10 P1 Z{-axes[3].position} 
      

      into the file and not (i.e.)

      G10 P1 Z-2.5
      

      Any ideas / solutions / different ways?

      thanks for your help!

        M500 P10 does save the tool offsets.
