The variable speed thing is not really that much of a problem, the problem is when you need to print a line right through the center. That tangential speed has keep going up the closer you get to the center to maintain a smooth printing path, obviously you're never going to need to print so close to need an infinite rotation speed, but you can get close enough to make the speed unreasonable. It was enough for the Reprap community to effectively give up on it, but of course, the whole problem is solved by not having continuous lines go through a region in the middle, and just adding that restriction into the slicer, which they may as well write specifically for this machine to incorporate spiral fill and other neat things a polar printer can do to vastly increase printing speed that a Cartesian printer can't.
