Hello there, I had marvelous prints at 0.2mm (Microswiss all metall hotend on FF Creator “pro”) with some black ABS, then when I switched to orange, (230° temp on the nozzle) it almost immediatly clogged. I check, it aint anything else that the nozzle himself. I can see some orange filament from the back of the -unscrewed- head. I cant push anythiong in even at 240° and I dont have 0.2mm curing sticks so I’m kindo blocked. Unfortunate, I printed 10 great parts in black, and the very last two in orange are on hold.
Any ideas?
Guitar strings can work and they also make micro drill bits you can get.
Too bad I dont have a guitar :-). I guess I’ll order some of these micro drills, but even the 0.4 are so fragile!!!
I read on other forums that the sound cables are often made of 0.18mm thick strings.
But what worked for me was to use my cooking torch two or 3 times then plunging the very hot nozzle into water. It got very clean and I was finaly able to see through. I still have to test with this orange filament though. Keep u posted!
Heat it up to around 200C, release the feeder if it’s spring loaded so you can push, pull and turn the filament. Get a piece of filament for about 10" and make sure when you twist it, it doesn’t break easily. Then get a drill and use the filament as a drill bit, one side of filament goes to the drill and the other to the extruder, start pushing and drill very slowly, then stop, bring the temp to 140C and pull the filament out of extruder very very slowly to let the filament pull out whatever is remained in the nozzle, cut the filament and do it again until the filament comes out of the nozzle when you push. If you don’t have a drill use a pliers or something. ABS is better.

That seems a smart solution if you do not want to dissasemble everything. I’ll try next time, good idea, thanks!!!
So, This is how I did:
A blue flame (using a cooking torch) and cold water. I first tried just warming enough then plunge in water. Not doing much. Then I decided to burn everything, then the cold bath, then again. That did the trick. I was worried that they could be some residue but then I thought, given how hot it went (glowing red on some of it) whatever is left would probably be some dust that a 0.2mm nozzle can spit out. I was right. And it is printing very well. As new. Thanks for the other tips, I’ll keep them for the next issue !
