I have just bought my son a used Flashforge Adventurer 3 and the man who sold it to me said he had a bit of trouble with the filament starting to come out before it touches the print bed but if you just grab the filament with a pair of tweezers right before it hits the bed it prints fine.
Does anyone have a way to fix the problem I'm a 3D printing virgin and it is being delivered today so I don't want it to be a problem for my boy.
