Re: [CAD_CAM_EDM_DRO] virtual hand jive

Rick,

The three goldmine encoders sound like a good idea (missed getting mine
8>( ), however I think you will want to stay in CNCpro, not exit it to
run manual. SO, we need to get encoder inputs INTO CNCpro, (MaxNC, any
chance?), or whatever control program. I had thought that a TSR program
could watch the encoder(s) on timer ticks, and add the appropriate keys
into the keyboard buffer, but as has been mentioned, the overflow could
kill ya! The TSR could still help to map a keyboard pendent into
program keys :>)

The "orthogonal directions" sounds interesting, put the encoder knobs
(handwheels) on three mutually perpendicular axis? ...And I was just
going to add a jog knob (with led's to remind me which axis I was
jogging, and selection p/b's)!
