After installing new FW 1.21 wrong finishing gcode

Computiger

Hello,

after installing new FW 1.21. I got trouble with my prints.
If my print is ending my extruder is running endless in reverse direction.

Is anything changed with FW doing?

Here my End Script:

[[language]]
G91 ;relative positioning
G1 E-1 F300  ;retract the filament a bit before lifting the nozzle
G90 ;absolute positioning
M104 S0 ;extruder heater off
M140 S0 ;heated bed heater off (if you have it)
G1 Y0 F9600
G1 X0
M84 ;steppers off
M106 S0 ;Fan off

are you using absolute extrusion (M82)? that would explain the issue you are having.

Computiger

Yes I have set M82 in my starting script. But I never changed it. Bevor I´ve installed FW1.21 everything was working well.
Do I have to remove M82?

no just put M83 at the start of your end script.
Not sure, maybe before 1.21 the firmware did this for you.
I don't see anything related in 1.21 release notes, maybe David can answer this one…
