Possible bug on baby stepping reset

sverreb

In my printer profile for PETG I am adding some z offset by using baby stepping:

[[gcode]]
G28 ; 
G29 S1 ; Load and activate detailed bed map
G1 Y1.0 Z0.2 F1000.0 ; prepare to prime
G92 E0 ; reset extrusion distance
G1 X60.0 E9.0  F1000.0 ; priming
G1 X100.0 E12.5  F1000.0 ; priming
M290 S0.20 ; set baby stepping

This works perfectly the first time, however if I make a second print (which uses the same starting script) I see the printer using 0.4mm baby stepping offset.
The documentation states that homing should reset baby stepping but in my case it does not appear to do so.

I’ve noticed the same effect with firmware Build 1.20

Thanks, I have this on my list to test.

Yep noticed this too

I have a feeling that this behaviour was deliberately changed in firmware 1.20 because several users complained that babystepping wasn't remembered from one print to the next.
