This is a very good extruder design.
@Jonathan , have you printed and tried it? I saw this file a while back but haven’t made the time to experiment with it.
Id like to see this modified for 3mm!
@Tim_Sills I started to do the pincher arm, but had a jam. I’m also trying to figure out what’s making my prints warp. The peice that I did start looked to be compatible with the real aluminium version of the extruder that I have.
My stepper will stall before the fillament will slipp. Awesome job @Brook_Drumm !
