I finally got my brand new Original i3 MK2 to print properly and after a successful print last night, my extruder is clogged. All I did was switch filaments and the new filament would not load. I tried to go back to the original filament and it wouldn't load either. I then went back to a 3rd filament that I have done successful prints with and that one wouldn't load either.
I checked the manual for the MK2 and follow the instructions of I visually checking the extruder gear, and cleaning the nozzle.
The nozzle feels clean with little to no resistance, and the needle that came with the MK2 goes almost all the way in, at least 1-2 inches.
After once again preheating the nozzle to 210c (I'm using PLA), checking the extruder (which was clean) and cleaning the nozzle I then went and manually fed the filament and after about 2 inches, I hit a "Hard" stop. I made a black mark on the filament where the stop occurs, its about 2 inches down.
Manual Filament loading
Although the nozzle is hot, the filament, when fully inserted to the backline you see in the photos, does not get hot or melt. I think there is a stuck piece of PLA somewhere inside the middle of the extruder.
Is there any fix for this? Or do I have to take apart the extruder? or buy another one? Is it normal for a brand new extruder to get clogged like this? Also can anyone give me any tips on how to prevent this from happening again? As I mentioned I just finished a successful print the night before and it was about 3-5 hours before I got to check on it in the morning.
