Extrusion Problems - Clicking Noise
Since yesterday i am having issues with my printer. At first there was no extrusion, after contacting the prusa support i adjusted the tension of the Idler screw. After that step it worked flawlessly again. For whatever reason without changing anything my printer is now doing this today:
What sort of problem is this and how can i fix it?
RE: Extrusion Problems - Clicking Noise
It seems that i can not upload the video so i will describe it. The gears try to feed the filament into the extruder but they snap back up midway through feeding and that motion makes a clicking sound.
RE: Extrusion Problems - Clicking Noise
A number of things can cause this, check your gears and make sure there isn't filament dust filling the grooves that grab the filament, if they're filled you won't get a good grab. You may have a clog in the nozzle that's increasing resistance as it tries to push through. Your nozzle temp setting may be too low for the filament, if you're trying to print PETG with PLA settings you may get this. Your thermister in the heat block may not be registering the correct temperature, if it thinks the heat block is at the right temperature but is really too cold this could happen. Lastly there's heat creep. This isn't so much a problem with the I3 Prusas, but is a possibility especially if you didn't get the extruder assembly assembled quite right.
On your video make sure the file isn't too large, you may need to reduce the amount of time you're trying to capture or render it to a lower resolution.

Thanks for your answer.
The gears look clean, nozzle also looked clean. I was just using pla and i tried using a range of different temperatures but it didn't seem to change the problem.
Thermistor could be possible but i don't believe so. I checked on the ptfe tube but it looked fine to me.
In the video i was only using the Load filament feature, trying to extrude some filament.
That's what's so weird about it. The most plausible solutions don't change it. I will update if i have found a solution but currently i have no clue what the problem could be.
