I am finally getting back to a old project to retrofit a huge Sharnoa knee mill with Mach 3. In reviewing all I had planned, I found one item that I hadn't figured out. The original Z axis drive motor has a built in brake...how does that work? I forgot to mention that I will be using Rutex 2020 axis drives on all axis'. Do I just remove the brake unit, or is there some way to operate it from the pc/mach3/rutex drives?
