So I added the guide to sit over the e3d top piece, with a whole drilled out for the ptfe tube. So far,its been alot better but I think the tension is still too tight, since it occasionally starts grinding into the filament leaving a groove where it stops feeding, and a half complete print with a sudden stop. Now 3 out of 4 prints complete successfully, with a 7hr job running fine on the first tr

I actually had a good print of TPE at 15mm/s with the old hot end, with no tube using an abs disc with a 5/64in drilled hole with a chamfer on top.

Didnt expect normal stiff filaments to have so much trouble with it though, the abs and petg is kindve surprising.
From here, ill try to guide, I ca

Good thought. Ill try to make a support disc with a 3/16in hole to stop maybe 2-3mm from the top of the ptfe tube. I upped the temps a bit, and disabled firmware retraction and I got one print out, but it took two tries, as the first crimped 30min in.

I was having issues with flexible filaments, and needed to print polycarbonate, so I changed my Threeup V3 hotend from the e3d clone it came with to an e3d v6. I set the ptfe tube so it just barely misses touching the mk7 drive gear. Within 20 minutes of starting a print with seemingly any filament (petg and abs so far), it somehow crimps around the ptfe tube and feeds into the carriage assembly.
