Experimenting with my DIY Y-switch dual extrusion setup.
I think i’ve nailed down the G code retraction sequence for the PLA I’m testing with - nice pointed retraction ends without any “whiskers”.
The key (for me) is a F1000 retraction of 10mm, then a 2mm reinsert at F250, then the final retract past the Y split at F7000.
Reinsertion is F7000 to the 10mm before the melt zone, then F250 for the final 10mm into the melt zone.
I’ve been printing with these settings for a few hours, and have yet to jam.
