I have been attempting to get my Anet to print for a couple months now. Haven't had a huge amount of time but when I have I've worked on it. A lot of the problems I have had I have been able to trouble shoot, for example for a while I was unable to get any filament to lay, and I have since fixed this issue. Now however my filament will extrude but it is very spacey, and not solid. I have tried re-calibrating the bed, un-clogging the extruder, and increasing the flow rate but nothing works. Is it possible that I have a bad board and that is causing my problem?
