This is what happens if you try to extrude when an XCR NV6 hot end is too cold while using a geared extruder (attached).

The filament bunched up inside the funnel section of the teflon throat and broke off when the extruder attempted a retract. Must have happened during a failed print last night - was wondering why I couldn't extrude anything this morning.

Clearly Marlin's #define EXTRUDE_MINTEMP 170 is too low and I need to up it to 185 or so. :)

geared extruder = brute force goodness. Glad you where able to get it all out.

WOW! that might be what has happened to my geeetech a20m.. a couple nights ago I finished a PETG print and when swuitched to PLA for the next one the firmware failed, a few restarts and then the PLA wouldn't get out, nor the PTFE... both stuck.. and at first I could manually extrude or using the menu option...

Cool Model, care to share the .stl

LoL
