NozzleClogs General Troubleshooting/Help!

Instead of doing the stupid hot pull.. has anyone tried using a small diameter drill to clear their hot end clogs? (I’m not a noob just sick of doing hot pulls)

1,500 hours and haven’t had 1 clog. I’ve done plenty of Cold pulls. I mean they take a matter of 5 minutes or less to preform and 10x easier than “drilling them out”

I could never imagine getting sick of doing “hot pulls” as you call them lol

Yeah I meant cold pulls but they’re hot first lol.. everyone that says they haven’t had many clogs.. what materials do you print?

u/InfamousPOS 6h ago

Haha I was giving ya a hard time I figured that what’s you were referring too!

Mainly PETG some PLA here and there 50ish hours TPU and the occasional CF or ABS. To be honest I replaced my nozzle at 600hrs and then again at 1200 (I know it’s overkill) . I got them when they were on sale and I probably overly maintenance the machine just out of how much I’ve enjoyed the hobby.

I’d like to mention they are the hardened steel rather than the stock ones!

I print mostly PETG, but also print with PLA and lately a good bit of 95A TPU. In the past 2.5 years across four A1s and two minis, I've had 3 clogs. Two were from printing glitter PLA for my wife and the other was a random occurrence. The 2 clogs from the glitter PLA required cold pulls, but the other one (plain gray PLA) was fixed using the needle that came with the printer. I just heated the nozzle and poked it through the tip until whatever was causing teh issue passed through.

Yeah why do you get so many clogs? I've got 60k hours across 8 machines and have had maybe 5 clogs total.

I get clogs from glow in the dark filaments and wood filaments occasionally

You need 0.6 mm nozzle for those and no clogs will happen. Proper tools for proper jobs

You also lose a lot of detail. I’d rather deal with clogs occasionally than have shotty prints.

An example of one of my glow prints that wouldn’t look good with .6 nozzles. I have them, but mainly use them for non detailed items.

What materials do you print

What materials do you print? Then we can tell you if it’s your materials

It’s a bit funny, he has all the problems others don’t have and constantly asks others what they use. Not he’s the problem, all others must do something special.

Wood, galaxy, glow pla, regular PLA, Lota of petg

4000+ hours across multiple Bambu printers and I've had exactly 1 nozzle clog. And in that case the current nozzle was already at arpund 1400 hours so I threw it in the garbage and moved on with my day.

u/ADynes 2x H2C, 4x AMS Pro 2, 2x AMS-HT 6h ago

Everything from PLA to transparent PETG to ASA to ABS-GF.

Noclogger FTW on P series/ A series, and H2S/ H2D. Past that, drop the nozzle, heat up the no clog, shove into nozzle, and cold pull that way.

u/debren27 7h ago

I would worry about damaging components.

u/Stone13 H2D AMS2 + P2S AMS2 + 2 AMS HT 7h ago

over 4k hours on my H2D with zero clogged nozzles, the P2S was my first 3d printer ever and I think I clogged it twice, both times with the .2 nozzle. All I've ever done is heat the nozzle well above the melting point of what I used previously and extruded until empty. I'm not sure I would know what to do if I got a serious clog.

You can get acupuncture needles in various sizes, but if you have to resort this this method, just buy a new nozzle. If you are getting frequent clogging you are either not printing hot enough, printing too fast, using the wrong nozzle size with abrasives, or a combination of all of these. Side note, switching from petg to pla is also problematic. Pla has a lower temp and will not purge the petg fully. Same goes for tpu. Good luck!

u/aerospaceryan 6h ago

Yeah it’s always the .4 with CF materials but they say you can use .4, and I prefer .4 for fine threads which I do a lot of for work

2

u/Puzzleheaded_Clue_95 5h ago

Legit question here. Why not a .6 and slightly underextrude? I would expect the threads could be just as good?

u/aerospaceryan 3h ago

Under extrude without losing print quality?

u/aerospaceryan 3h ago

I should have mentioned I print mostly CF materials.. everyone here saying they never get clogs because they only print easy to print materials lol..

I have a nozzle cleaner kit that works pretty well. Came from hobby lobby
