Re: [CAD_CAM_EDM_DRO] Re: CNC Painting

Ohhhh !!! That kind of painting !
I know what I would do.... I would build an "Arm" capable of multi-axis moves large enough to cover your area.

I'd use Indexer lpt as the control because quite frankly, it will be the most robust, most useful, and best bang for the buck for THAT specific application. It can be configured to "learn", so no
radical Cam programs would be necessary to get it to run to the right spots, after all, it is not like machining. Add to that, a pass or two on a part, would allow you to fine tune accelerations,
speeds and delay times because Indexers code allows for this *on the fly*. Why others have not applied this to your typical G-code control I do not know. I guess no-one made a G or M code for it way
back when, so we must not need or want it.

I would imagine that one could use the spindle rpm output to handle variable Fluid delivery as well, because this too is easily handled in the code.

That "Indexer" program..Wow... I think Art Volta has something there, that no one else has been able to duplicate that I know of. While everyone (Ok, not everyone) is out chasing the "block box" world
or reinventing low cost Control, Art's still doing it with older hardware and smoother motion. Well, it is at the expense of some things not being "Real Time" like screen updates. For your application,
who cares !

I'd be curious to get an update from Group members using their new G-code interface, especially the new real time feedrate override. I do not know how he can do that with as much "lookahead" as Indexer
now applies.

It'd be way cool to do. Gonna yank my copy of Indexer off the shelf, blow off the dust, and make something like that someday.. Maybe a Robotic sandblaster......
