Re: [CAD_CAM_EDM_DRO] What is wanted in a controller,

Hi Brian,

Instead of the buttons, you could use another encoder, but the cost goes
up an encoder could be shared by the feed and spindle menus. I haven't
seen a "Dx to go" display, I just watch the numbers spin! As a
programmed menu, the overrides could be anything you want.
