RE: [CAD_CAM_EDM_DRO] Windows Step/Dir driver for coordinate measurements

You have not tried Master5 or Mach1 then. They are both windows based
controllers that have a very smooth pulse train. Mach1 does in on
Win2000 or XP and I would judge it as smooth as the DeskWinNC controller
that I have. Art is doing great work with this. Check it out at
