After slicing what I thought was a 'simple' circle (2.4mm thick wall, with a .4 nozzle, so the slicer results -look- like 6 even walls), while printing it had some odd behavior in the center walls so I tried loading the gcode back into Cura to see what it looked like. The gcode rendering has 'bumps' in the image, and I was wondering just how accurate the gcode rendering in Cura is, and if the gcode really does have all those 'bumps' in it?
