So, the only difference between the "hobby" world vs what I do everyday is a stepper motor without feedback and a system like fanuc that has feedback. The mach3 is the only level that I have not played with yet. It sounds simple enough to me. The software "mach3" uses the step of the motor and the pitch of the ball screw to calculate machine movement. You also assign "M & G" codes to other machine functions. So now I need to make sure that mach3 is configured to the way I want to program it. I will be programming it for imperial so I need to re-configure it for that and this is where the video come in? After that, I need a "simple" to use program to program my setup. I need to have a post processor that fits the machine. New question, when I get the software, which company will give the best tech support and supply the necessary post?
