I have a monoprice select mini 3d printer v1 and I can’t get the filament to feed through when printing. I have tried re-running the filament and when I heat the tip and manually push, the filament comes out, so I don’t think that it’s a jam. Also after I re-ran the filament, some of it was coming out without me putting any pressure on it. It wasn’t much, but some was still coming out. This would stop when I tried to print something.
