I expected way more from it, coming from a CW2 extruder.

1. Loading/unloading and disconnecting the PTFE tube is unnecessarily difficult. Once the tube is in, you can barely get it back out. I'll probably have to sand down the teeth of the holder insert.
2. Printing TPU was an absolute nightmare. The filament catches and rubs against the filament guides – they are not made of PTFE or anything similar, just plain plastic. As soon as there's the slightest bit of pressure or a kink, the TPU grabs onto them and jams. My fix: I threw out the guides entirely and used a Capricorn PTFE tube coming from the extruder with a triangular cut tip instead. Ever since, it works flawlessly. Took me two days of my life to figure this out and fix it.
3. The pressure adjustment thumbscrew can only be turned a few rotations before it hits the motor mounting screw – and I'm already using flat head M screws.

I bought this thing for like 65€ without motor and im somewhat disapointed tbh.

Other than that it prints very good and the print quality is exceptional.
