Can you explain what specifically was changed for the “Adjusted Z_MAX_POS to allow Z and XYZ calibration.” portions or provide the source that compiled the above firmware?

If possible for future compiles, a link to the GitHub or other location for source would be nice for those who need to compile other changes into the firmware.

Hey guys,

Do we need to make any changes to the PrusaSlicer configuration, specifically with regards to the extruder setttings? I saw the note regarding the estep and zmax changes in the firmware, just wondering if the change takes into account gcode generated by the app.

FYI: For anyone reading this, if you do the firmware update you do NOT need to make any extruder settings. As long as you did the firmware update and erased the full EEPROM then you won’t have any issues. Confirmed having just done this process on my mk3s today.
