Hello,
My print nozzles keep getting clogged while printing and the print messes up. What can I do to unclog them? I've tried turning the temperature up to 220 to see if that would help but it doesn't seem to.
Thanks,

I had the same problem. The solution was in cura the g-code flavor. By my mistake it was in marlin volumetric. When i change this in marlin everything was better.
The pfte tubes have to be fully inserted into the hotend. If the clogs are consistent then it's a good indicator that they might not be installed correctly. The hotend internals must be fully cleaned (a difficult process) and the tubes installed correctly
I had a couple good prints, but now I'm getting constant clogs. I had a bit of a mess where my filament leaked up onto the top of the heater block. I've since cleaned that up, but I'm guessing there's still a bit of filament stuck on the threads inside the block that I can't clean up(need to have the block up to temp in order to screw in the throat/nozzle), so I don't get a clean join between the heat exchange throat and the nozzle, causing more leaks and clogs. Any ideas how to fully clean the block, or solve the minor leakage I'm getting inside?
Same issue here probably. There's hardly any filament coming out of the nozzle now... So a fine needle it is, will try.
A needle could work as long as it's super thin. It needs to fit into the nozzle without forcing it. The micro pcb bits make it a little easier because the spiral cutting channels help pull the debris or burnt clogged filament out. A pack of them are pretty cheap on amazon and wouldn't be a bad investment. They make these situations easier
Which nozzle size are you using and are you using the steel or brass nozzles? With other printers I've had I've used very small PCB drill bits to unclog the nozzles (very carefully and only in hand, not in an actuall drill of course) while hot. If you're using your own filament that may have collected some dust (it doesn't take much) or if you're printer is set up in a less than perfectly clean area then you can set a dust catcher right before the filament sensors. You can clip a cut piece of sponge with a light oil application over the filament going into a 3d printer and it will help catch debris and reduce the chance of clogs
