Always unload filament after bed leveling MK2.5S


i updated the firmware (prusa3d_fw_MK25S_3_7_0_RAMBo13a_en-de.hex) of my Prusa MK2.5S to the latest firmware (3.7.1) and the latest Prusaslicer  (2.0).

If i start a print, the printer always unload the filament after the bed leveling. Right before it should extrude the intro line.

If i let the printer unload the filament and reload it, he moves to the 0,0 and it will unload again.


This is the start g-code from my Prusaslicer (should be standard).

M115 U3.7.1 ; tell printer latest fw version
G90 ; use absolute coordinates
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 F1000.0 ; go outside print area
G92 E0.0
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
G92 E0.0

I downgraded the firmware to 3.6.0 and did the first setup wizard. Now everything works.
