Repetier clicks, but doesn't extrude
Hi! This is getting a bit frustrating. Halfway (maybe not even that far) through a print, PLA no longer extrudes. There's a loud, repetitive clicking sound while it is trying to push the filament through. ABS works fine so I thought I just had a bad go at cheap PLA so I picked up name brand stuff (I found this one). Same problem. With the Repetier mod, you can change extrusion temps right from the LCD so I played with that without improvement. To be fair, ABS print quality isn't great, but at least it will finish a job. I don't understand what is wrong. I'll take the machine apart and clean everything, but aside from that, anyone have any ideas?
