      Re: Saving M208 (axis min/max) values in config-override.g possible?

      Has there been a change in rep rap firmware?
      Somehow I'm getting an M208 to the config-override.
      And I don't want it. After a print (or the print is canceled) I'm not able to travel to the initial Z Max

        @Kiwi-0 Normally M208 isn't saved to config-override.g. However, if you have used a G1 H3 move, and subsequent M500 will save M208. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m500-store-parameters

        Check your homing macros for any G1 H3 moves. These do the following:

        H3 terminate the move when the endstop switch is triggered and set the axis limit to the current position, overriding the value that was set by M208.

          Thanks for the hint with the H3
          It was in the toolchange macro and probably a heatertuning with a M500 at the end brought it do the override...

          Thanks a lot!
