Also I made external perimeters painfully slow, while keeping internal ones and infill at a more reasonable speed.

It combines 3D and inkjet printing … Will check the 'level' again before we start on the light color squares. The acceleration and jerk also had the combined effect of reducing the amount of vibration the printer caused, the damn thing was translating through the table, into the wall and rattling my garage roof! Wish I had a way to machine the bed flatter or something to deal with the odd layer 1 streaking, as it looks just right in some places, intermixed with too high or too low in others.
