I took the heatsink and fan off and raised the z height to about an inch so I could see exactly what was going on. No matter how tight or loose I set the spring tension the filament gets chewed up. Too loose and it just spins on there until it eats a hole through it. Tight enough for it to actually extrude consistently and it chews a hole through anyway.
Compared to the tinyboy, it looks like the mpcnc extruder is spinning way faster to put out the same amount of material even though they have the exact same gear on them with no reduction.
Unfortunately I won’t be able to really work on it again until the 21st because I leave campus tomorrow for a robotics competition and from there I go on spring break.
