The one thing to look for is a controller with constant vectoring.
I am under the impression that some controllers have a harder time cutting circles and arcs. Why is this and what do I need to look for when selecting a controller as my machine will cut a lot of circles / radius etc.
Check out what I am working on at www.routerbitz.com!
It's not only the controller that can cause poor results when milling arcs and circles. If you don't have a tight machine with very little backlash you will see problems on cut circles in the 4 quadrants. This is where the motor must change direction and this is where you will see the quality of your machine. If you have see small gouges or flats on the 4 quadrants of a circle then your machine has some backlash that is causing this.
