Re: [CAD_CAM_EDM_DRO] Interesting parallel port relay board

Hi Jeff,

Dontronics is "good people" to do business with! I can recommend them,
got some PIC stuff some time ago.

As far as controlling a spindle or coolant, I'd still have to go with an
SSR (Solid State Relay). These can be connected per my Driver/PS
schematic, as I posted yesterday.
