Ok i finally got around to setting up a 4'th axis, question can i use mach 3 mill or do i have to configure mach 3 turn? i will be using it to slot holes in cylinders.
You can use MachMill. You will have to configure the 4th axis in the setup just like you did your other axis. The units are set up as degrees and not as inches. In the config you will have to tick if the axis is rotary or linear. Tune the motor and away you go......ahhh if it were always that easy. This should give you a good overview of what you will need to do.
