i was about to start a new topic. i recently upgrade to 3.5.0-Beta3 and now i have extruder issues. I use 2 toolboards 1LC on an IDEX machine. It appears that my extruder motor stops extruding during printing. it seems to happen right after a toolchange to select the new extruder. The toolchange does some fast extrude retraction.
Once this behavior happens i have to reboot the printer to restore back to normal behavior.
I am reverting back to firmware 3.4.2 for now. hopefully my issue is part of this fix in the Beta 4 next release.
