It doesen't seem to round corners off very much. Interesting to watch it run over a complex contour, accelerates and decellerates but not jerky at all. You can change that in the setup but I have left it as it was sent. Control also has a "broken Point" feature, if you need to change a tool during a cut you can stop it and have it save where it was, jog away and change the tool, etset the length, and it will restart where it left off. Also will do multiple parts in an array, you tell it the X and Y spacings and how many parts in the grid. Hardest part of it is the converted chinese instruction manual...
