I need a script command to tell the extruder to stop and retract filament at the end of print as mine keeps oozing a certain amount of filament when print is finished while the extruder is lifting to go to park position.
Is this a good question?
I modify my end g-code so my extruder retract the left over filament. My loading offset is around 90mm, I command it to retract 100mm.
here is the example:
G91 ; relative mode
G1 Z10 ; lift 10mm
G1 E-100 F200
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G90 ; absolute mode
G28 X0 ; home X axis
M84 ; disable motors

Hi Mounir,
Please could you share your end sequence with us? That way we can compare it to ours and look for any errors.
Thanks,
Guy

END OF PRINT
1 M106 SO; turn off cooling fan
2 M104 SO; turn off extruder
3 M140 SO; turn off bed
4 G1 Z100 ; lift extruder - added by me***
5 G1 XO Y200 ; part removal
6 M84; disable motors
7 M900 KO; reset linear advance to off by default
Hi Mounir, it looks like in several places you have the letter O, rather than the number 0:
1 M106 S'O'
2 M104 S'O'
3 M140 S'O'
5 G1 X'O' Y200
7 M900 K'O'
Please correct these and change them to 0s!
To retract your extruder, please insert the following two lines at the beginning of your end sequence:
M83 ; set extruder to relative mode
G1 E-<DESTRING> ; retract using project settings
(If you're using PrinterScript, the second line will instead be: "G1 E-{{retractDistance}} F{{retractSpeed * 60}} ; retract using project settings" )
Let me know if you have any problems or questions.
