Wipe and prime motion at the end of resume.g



  • It would be nice if the retraction-correcting-extrusion at the very end of the resume.g macro would happen after the nozzle was touching the part in some sort of a wipe-and-prime fashion. Because the pause.g file is not controlled by the slicer, I can't figure out how to fix my oozing problem caused by print resuming at every layer.



  • Not sure if i follow properly, You want it to wipe before the it resumes the print (before it starts printing the wall/infill)
    if so couldn't you just put a move/extrude before the
    :- G1 R1 X0 Y0 Z5 F6000 ; go to 5mm above position of the last print move,
    like
    G1 X"wipe area" Y"wipe area" Z"wipe area" F6000
    G1 X"wipe move" Y"wipe move" Z"wipe move" E"extrude filament" F1000

    Yes, something like this. Basically, if you watch the nozzle during a resume.g you will see it move to where it is hovering over the last print location, then as it drops onto the part to begin printing again, it extrudes/oozes some filament into the air. This tail is then deposited onto the part (usually at some point on the skin) and the printing begins again. It would be nice if the resume.g could wipe along already printed geometry as it does the retraction correcting extrusion - The "G1 E10 F3600 ; extrude 10mm of filament" at the end of resume.g

    This isn't such a big deal if you are only doing a couple of pauses during a print, but when doing the octolapse style time lapse, it becomes an issue.

    That means you don't have your resume.g file set up correctly. Before the G1 E move to re-prime the nozzle, you need G1 R1 X0 Y0 Z0. If you have had your Duet for a long time, you may have G1 R1 with no other parameters there, but that won't work any more.
