Bill, Thanks for the response! I popped the extruder motor out, and sure enough that grub screw was loose. I tightened it and that seemed to fix T1 (and T3, but I didn't play with that one much). I must've screwed up the g-code, so I'll re-generate that and see if it'll fix T2 and T3 while printing. Thanks! Clara

I'm going to be honest, I don't like this extruder either. I wish I had done more research before buying it. Is there an extruder that you personally recommend? I've flared the PTFE tube like you did in the video, and it appears to be loading and unloading correctly now. I'm going to try a test print and see what happens. Thanks!

Thanks Bill!
