You should take it all apart and find which part is plugged up and fix it by acetone, burning or drilling depending on which part.

So is there any solution for this problem? Also I would rather by a replacement part instead of the whole hotend, so what part should I buy?

Thanks Gordym, I might have to take you up on that. I have to set aside printing issues for a few weeks though till school settles down.

Though, this "looping" problem occurred on these hotends as well. Compounding this problem is not having another printer to fix and tweak the extruder mounts to correctly hold the hotend.

I live about 45 minutes south of Jackson (Adrian, MI). If you want a part printed, let me know and I can mail it to you.

Coleke, what have you been doing just buying a new barrel or PEEK or something else?

Yeah that's exactly what it does. It extrudes maybe 15mm not sure than it bends. Also what is weird that I forgot to say is if the temperature is still on after the filament is out, slightly melted filament left in the barrel tends to creep out slowly from the top. Which I think that is from heat rising.

I have been having the same problem, with multiple hot ends. First was the hot end barrel and heater element from Qu-bd. Then my PEEK barrel broke when making sure it was snug against the barrel. Now I am having the same problems with a hot end I ordered on ebay. When you get it to extrude, does it start to print, then bend the plastic in loops between the peek and extruder motor?

I got the new barrel from makergear with both ends turned down which I think is the same type as the solidoodle type. Also I did think that the PEEK wasn't tight enough at first so I cleaned out the barrel and nozzle and tightened but it's still clogged. If I haven't cleaned the barrel/nozzle and I take the filament out and put it in it doesn't extrude at all. But if I clean it it extrudes some but hardly any and takes a lot of force to do so. Also I don't think any thermal past is in there because the barrel and nozzle are both new and also with my old barrel and nozzle (stock) I never used thermal paste and it had the same type of clog so that's why I think it's the PEEK.

So, the new barrel you got.... was it from SD or is it the same(but slightly different) maybe non-beveled end version barrel?

I'm betting you haven't threaded it tightly enough into the PEEK. If you take the filament all the way out, then feed it in again, does it extrude? For how long?

I read another post about defective thermal paste that caused a clog. I do not know where this paste is located or how to tell if it is faulty. Maybe someone else can help you determine if this is the problem. If this is the case Solidoodle should replace the parts at no cost other than time.

So first I had a clog a week ago and accidentally bent the barrel from getting it off. So i bought a new barrel and a new nozzle because i wanted to experiment with a .25mm nozzle. But I installed them both and I haven't printed a single thing because it's clog. Also I know the nozzle and barrel are the right temperature because I bought a cheap food thermometer and the temperature was around 230. The only conclusion I can come up with is that the PEEK is clogging but when I take it apart there is filament inside the barrel so there might just be a lot of friction I don't know.
