Saving M208 to config-override.g

[Kiwi 0]

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.

@droftarts
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!
