Bonjour

j ai bien modifier dans configuration h #define MIN_SOFTWARE_ENDSTOP_Z
#define HOMING_FEEDRATE_XY (100*60)
#define HOMING_FEEDRATE_Z (25*60)

Hi,

I also have a lot of issues with this version. Even if I am also french I will try to explain in english.

I installed this firmware, and I have well calibrated all printer settings but :
- no way to finish a bed leveling ==> the nozzle always crashed in the plate at a moment or another (I mean not always at the same point/corner)
- No possible anymore to authorize a Z under 0 ==> quite annoying to define and set the Z Offset (a lots of tries required)

I am also really sinterested in having a bugfix for this release. (The previous release were really bad and with this one we are not so far to have something good)

Thank you for your support.
Stéphane

Another point that I can't figure out is how to add steps for the second extruder. There is only on extruder available in Marlin UI...
