This nasty clog made printing with ABS nearly impossible for 3 weeks out of this machine. Quarry dust, nylon, and high humidity did some serious damage. This is the first time in almost two years a nylon cold pull was unsuccessful.
Time to go old school and burn it out, right?
If it’s ABS you can just dissolve it with acetone, right? And for nylon dissolve with phenol, cresol, or formic acid.
Seems odd to me everyone struggling with clogs, trying to pull, burn, or drill them out instead of just dissolving them.
The gottcha is that it’s often not the material you’re printing with that caused the clog. Accumulate enough synthetic fibres, dust and other non-thermoplastic contaminants over time and burning it out lands up being the only consistent solution. The only time this doesn’t work and you need some mechanical assistance is when little metal chips have made their way into the nozzle.
Ah ok, I didn’t realize the clogs were from contaminates. Good info, thanks!
Yea this is definitely from contaminates. There’s a multi-colored sludge being held by fibers of some sort, looks like torching the living shit out of it is the only thing left. Luckily I got spares tho.
I may want to invest in an ultrasound plate for putting jars of acetone on to dissolve my rare jams easier. The last time took me 24 hours to clear.
It’s a good idea to clean out the nozzle with the nylon-pull technique now and then. It will help prevent clogs from buildup.
Yea it seems to work better if you just regularly do it instead of when there is a clog. Get that gunk out before it causes trouble.
Yeah, it’s probably better to be proactive though personally I have used it when the clog already happened. You have to be able to remove enough filament to get the nylon into the nozzle. In your picture the clog seem to fill the nozzle.
