Hello I recently bought a Raider cnc milling machine that has a Colorado Numerical Control on it. I don't have a programming manual and I started to punch in a program to run and it said it does not recognize G41 G43 . I wanted to know does this controller use radius comp. ? I have never used a cnc that did not use radius comp but this thing is about 25 years old and pretty basic. Has anyone used one.? Does anyone have a manual ?
