Diamondback nozzle clogged
My diamondback nozzle is clogged. Even if the CORE One could do a cold pull I think I'm beyond that. It's clogged with carbon fiber PETG. Extruder just clicks and won't feed. I disassembled things and it stuck a wire down to probe, seems the clog is right around the heat break.
Any suggestions? Are these sturdy enough I can take a propane torch to it and get it red hot to burn stuff out? Do I soak it for a month in some solvent? Right now it's a pretty expensive paperweight. I had hoped this was the last nozzle I'd ever buy.
For now I'm back on the trusty tungsten carbide nozzle with adapter. At least I can disassemble that thing if I had a problem (never have though).
RE: Diamondback nozzle clogged
I have precisely the same problem.
I heated it with a lighter. I left it for days in aceton and it didn’t help
So I would also be glad with a solution.

E3D specifically say not to use a blowtorch: Prusa Support: DiamondBack Nextruder Nozzles
You can do a cold pull with the Core One. Just install the 6.4.0-RC firmware. There is now a cold pull guide.

I used my hot air rework station to clear out a clogged obxidian nozzle. Stuck it inside the hot air outlet, let it get hot and purged it by shoving filament into the nozzle. The advantage of that over a blowtorch (!!!) is temperature control. The risk is that you're holding (hopefully with pliers) a very hot extruder.
RE:
I like the hot air rework station idea. I can set that to a certain temp. Thanks, I'll give it a try.
Regarding the RC firmware, I'm not interested in beta testing Prusa's stuff for them. Better things to do with my time. When it's release version I'll give it a try. I still don't think it will work though, since the clog is up in the heat break where it's not supposed to get hot enough to melt.

Although one could argue, you’ve been beta testing the Core One since you first turned on the power switch. I know I have.
As for the RC firmware, yes it has bugs. I’ve been running it for over a month and it’s pretty stable. I think most of the bugs found so far were probably already in the 6.3.4 firmware (except a really nasty XL docking bug that is new).
RE:
Hi, sorry for my english. I had exactly the same problem with the standard Prusa hardened nozzle. The hot air wasn't the solution, because there was filament residue with carbon fiber. I solved my problem with the long version of the drill bit of 1,8 mm diameter, length 81 mm. I inserted the drill bit into the drill and manually turned the nozzle. Next step were several manual cold pulls until nozzle wasn't perfectly clean.

So I've been reading this thread with the smug assertion that I had yet to experience a clog (after 3 months) with my diamondback nozzles. So last night I printed some PA-CF followed by PPA and guess what? My nozzle clogs. Two cold pulls later and I'm back in business but think "what a coincidence!" Anyway, the cold pull wizard in the 6.4.0-RC firmware got me through it.
RE: Diamondback nozzle clogged
Thanks for the tip. I ordered a 1/16" 6" drill bit (they seem to be common and cheap for rivet use). I'll try it in a pin vise when I heat it with the hot air station.
Beyond that, I'm actually happy with my tungsten carbide nozzle and will probably stick with that if no problems surface. Hopefully it lasts until the next firmware goes gold.

Just join the clogged diamondback club on my C1L, not impressed. Printed very little CF, clogged so quickly. Only partly unclogged so far. Hoping more cold pulls will work

Mine have only clogged one time and that's from use error when I switched from a lower temp filament to a higher temp and then back to lower temp without running cleaning filament through it like I normally do. Otherwise, they've been great.

All nozzles will clog if one doesn't take care of what types of filaments are run through them. Pick up some cleaning filament sticks removed the Bowden tube and feed them directly through the nextruder. Set the hot end to 290C then go to manual movement in the UI and move the extruder 50mm or so.
RE:
Many Cold Pulls and a little gentle help at the nozzle with the CNC Kitchen Nozzle Cleaning Wires, lots of purging. The initial clog left quickly, but the nozzle was partly clogged and did not want to give it up. I'm going to get some cleaning filament. The manual cold pull guide with PETG was better than the firmware which is for PLA, at a much lower temp. I was removing ABS CF, guessing I'm up sizing to 0.6 for CF. Granted I never had CF on the MK3S, 1 clog in 6 years.
RE: Diamondback nozzle clogged
Update from OP: I got the long 1/8" drill bit, put the nozzle in a spare heat block I had and stuck it in a vice. Heated with hot air solder station to 350C around the heat break area and ran the bit down attached to a pin vise I had. That seemed to get most of it out, about an inch worth. Drill bit now goes down about as far as the stock nozzle I used for comparison. After heating I was able to get a needle through the nozzle too. I can't see light through it so still not 100% clear, but I imagine if I put it back on I could load filament enough to do a cold pull (yay, new firmware) and then run cleaning filament and maybe get it back in service.
However, I'm not. My tungsten carbide nozzle has been rocking it and I really have to reason to put any more effort into the diamondback.
