Polar printers all follow the same rules, giving them all the same pros and cons:
Pros:
Well suited for a scanner, which they take advantage of.
Large print volume for very small x-axis travel.
Smooth printing of circular objects.
Cons:
Non-constant speed and resolution between the middle of the plate and the edge.
More complex math for the firmware to run to convert the Cartesian-based g-code to polar coordinates. (or a custom slicer that generates polar-based g-code)
Lines passing very near the center require very fast movement of the plate to make a smooth, constant line. (lines actually going through the center cannot keep a constant speed and must pause while the table turns.)
