After upgrading to 3.3.1 I have issues

[JohnathanSmith1969 0]

I am using a Select Plus Printer... After upgrading to the Mac version of Cura 3.3.1 today I have a issue after every job my printer makes a banging sound, the filament breaks off  and then I need to restart it to access the menus?

 

Can it be something in my End Gcode?

 

End Gcode:

M117 Cooling down . . .

M300 ;beep

M104 S0 ;extruder heater off

M140 S0 ;heated bed heater off (if you have it)

G91 ;relative positioning

G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure

G1 Z+0.5 E-5 X-20 Y-20 F9000 ;move Z up a bit and retract filament even more

M106 S255 ;fan at 100% to cool nozzle

G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way

G90 ;absolute positioning

G1 X100 Y190 ;move bed forward

M84 ;steppers off

M117 Cooling down . . .

G4 P120000 ;wait 2 minutes (120 seconds)

M106 S0 ;fan off

M117 Finished!!!

M300 ;beep

Not all firmwares set extrusion mode to relative using G91 (e.g. RepRap doesn't but Marlin does). Maybe you also need an M83? Doesn't really explain what you're seeing.
