Please help! After a month of not printing anything I came back, now I can’t print anything.
When I start printing the extruder starts clicking loudly and the print gets rough. I tried unclog going the hot end but I’m not sure if I did it right. I also ran new filament in case my filament was wet. Please help.
Is the drive gear skipping or is it grinding the filament, my extruder hs made the same noise with both of those problems so the sound itself isn’t too great of an indicator of what’s wrong.
And can you feed the filament by hand?
The print bed is to high. I had the click sound on mine I lower the printing bed, it went away.
@Aaron_Leclair I can feed filament by hand but it seems unusually hard also it sometimes grinds the filament. I don’t know what’s wrong it just stopped working.
Sounds like a problem with your hotend. I’m not too familiar with the unit design, maybe @Brook_Drumm could offer some insight, it could be that the nozzle is clogged or that it has loosened from the PEEK thermal barrier. I had an almost identical problem with my Jhead a couple months back, in my case it was a gap between the nozzle and the thermal break as well as a piece of foreign debris blocking the nozzle.
Try cleaning the hotend out by heating it to the glass transition point of your filament and then remove the filament. I feed it back in and remove it several times to see if it loosens/removes anything. A lot of people suggest using nylon filament to do this but I find pla or abs work fine.
Are you able to disassemble your hotend? You should be able to check if the nozzle has drifted/loosened by seeing if there is any filament plastic in inappropriate places such as in threads on the nozzle.
One or more of these:
Clogged tip / hotend
Filament diameter too large
Tip too close to bed on first layer
Extruder temp too low
Extruder spring tension too tight
Extruder driver is over or under driving (potentiometer should be at 1 o’clock)
My bet is that filament has “toasted” inside hotend and is causing friction. You can manually press filament through at temp and pull out quickly… Cut off last three inches, repeat Over and over until no discoloration is seen on filament. Alternate method, remove tip after reaching 200C and push a lot of filament through. Resistance should reduce as toasted filament gets pushed out and hotend tube is clean.
Good luck!

Best advice is obviously from above. Appears to be over-extruded, steps/mm.
I agree with brook. Make sure your thermistor is reading correctly too. Happened to me on my prusa with a cheap hot end. Thermister was giving really high readings and the hot end was not hot enough to extrude properly.
