OK SO IM STUCK .. im getting slight pla distortion the 1st 20 or so layers using simply3d software. ive tried heat and no heat on bed , with a fan and without. different nozzle temps so on and so on.. basically its no lifting off the bed it just the layers are rough.. maybe rising above the inside layers a little then it smooths out and looks perfect. i have this with abs also. im using a creator pro dual .. only have this with circle stuff , square and other types are ok . ive used rafts and outlins no luck.. any tips plz?
