After installing new FW 1.21 wrong finishing gcode

  • 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:

    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.

  • 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…

  • ok thank you. I will try it out 🙂
