so i have a flashforge finder, during a print the filament stopped coming out of the extruder, it continue to move, but the filament was not coming out, when i unloaded and reloaded the filament it would come out of the extruder, (tho it takes a bit more than force to get it to come out than before) the filament comes out, but when i would start a print job it would come out, it would when i would push filament down during the print, and it worked but i dont want to have to push the filament during the entire print jobs… help?
