#Severe clog in machine I can't fix.

Hello everyone. I have a Flashforge Finder and I discovered my printer is blocked. Upon disassembling the printer, it is indeed blocked with filament but the blockage is in a part of the nozzle that does not get heated, and thus does not melt.

It is completely stuck. I have tried trying to puncture it with printer cleaning needles, and trying to melt filament onto it to do a cold pull with no success. It does not shift or budge, and I have attempted to load/unload filament thinking it will shift the blockage, but it does not.

How would you go about fixing this? Thank you.

Hello! I'm sorry to hear about the blockage in your Flashforge Finder. Since traditional methods like using cleaning needles and attempting a cold pull have not been successful, you may want to try a more aggressive approach.

One option is to try using a nozzle cleaning drill or a nozzle cleaning kit specifically designed for clearing stubborn blockages. These tools are often more effective at breaking up and removing hardened filament clogs.

Alternatively, you could try soaking the blocked nozzle in a cleaning solution like acetone or a commercial filament cleaner to help soften the blockage.

If these methods still do not work, it may be necessary to replace the nozzle altogether. Make sure to follow the manufacturer's guidelines for disassembly and replacement to avoid causing further damage to your printer.

Good luck with resolving the blockage issue!

The filament stuck inside the machine is Elagoo PLA.

The machine is set to 220°c but can go higher.

I have used the cleaning needles to clean the nozzle from the bottom, but the blockage is at the top.

I have not attempted to use a hairdryer or other heating tool on this as it is very close to electrical circuits and I fear damaging it.

you can't come from the top with the needle?

#

if it's a hard stop, you're probably going to have to disassemble it all

Yeah the other dude managed to take it apart and get access to the clog

#

And remove it manually

I could try going at it with a sewing needle and twisting it to sort of "drill" into it?

Is it a wise idea to try and melt some PLA into the top of the clog and then pull it out to bring the clog up?

That's what the cold pull is

#

But I see what you mean

#

It's before the hot part

I didn't have any success with the cold pull before, but I'll try again today

Unfortunately this printer doesn't get any replacement parts produced nowadays so if I can't fix this clog I'm wondering if I should just bite the bullet and get a new printer entirely

If it won’t damage anything close to it, you can try sticking a soldering iron into it, turning the iron off so the PLA will cool and stick to the soldering iron, and then try a cold pull then. YMMV

Find a piece of bailing wire. Or something the diameter of filament and just heat it up with the lighter or something right there at the end of the clog as you put it into it trying to push it out. It may be a slow process as the filament will cool the wire. But it will all warm up over time.
