As a rookie at CNCing, I'm still learning a lot. So far I've drilled through my sacrifice board to the table...several times, fried one controller fried one power supply and wasted a lot of material. But there's hope I did cut two very good circles a couple of weeks ago! Since I am replacing my power supply and controller, I was wondering what the Smooth Stepper does for a machine and if I should add one? If I have a machine that's working fairly well what would it add? I promise I won't fry it.
