Aaron When you cut stuff with a lot of little cuts, especially curved cuts, the speed will always be slow. If you look at the constant velocity parameters of any CNC machine you will find that the machine has to accelerate and then decelerate again at the beginning and end of every cut or move. Unless you have a very light gantry with a huge acceleration, you will have a slow response. When the cuts are very short the machine does not have enough time to get to the requested feed rate before it has to slow down again. It is one of the pains of cutting 3D stuff.
