Im printing a cup thing and the printer is making ridges and then running them over, and its making the printer sounds horrible and alot of vibrasions, it is making alot of useless moves, circleing the cup and laying down no filiment...it makes ruff bumps, runs them over then circles back and forth before laying down a nice smoth layer, then doing it all over again..i hope the cup stays adhesioned.. is this normal???

Solved!!!! Duh, another beginner mistake.....i had a 2mm cup wall and the wall thickness is .8. 

So i made the cup 1.6mm thick..now the printer dosent try to fill a .4mm gap in sections it thinks it missed...
