Re: [CAD_CAM_EDM_DRO] Re: Was Chopper circuit - Now ver 3.2, G298

Alan,

Good points. People might even want to make a "Frog" type device or a mill X
power-feed with one. I have a PIC development kit that I haven't touched in
years. I'll have to dust it off and see what we could cram into a PIC. In
the mean time, who can volunteer to design or produce an inexpensive L297 PC
board for us?
