Topic: Qu-Bd hot end clog

Elmoret- I noticed you swapped out your hot-end for the qu-bd. I ordered the part and ended up putting a few washers above the aluminum heater block to help with cooling the upper end; I am using the smaller nozzle provided by qu-bd.  I can get it to extrude for a short time, then the filament stops advancing and then starts to bend at the peek until I have a giant loop of filament between the PEEK and the extruder gear.

Did you just give up on the qu-bd, or did you eventually get it working?

I am thinking I might have to change the retraction settings, but would like to hear if you (or anyone else here who has tried this extruder) have had any success with this.

Re: Qu-Bd hot end clog

You have to make REALLY sure you've threaded it all the way into the PEEK. It's a good design, it'll work, but typically trouble extruding has always been due to the threaded barrel not being threaded into the PEEK enough.
