Re: [CAD_CAM_EDM_DRO] Proper solid state relay to use for spindle control

Hi Alex,

I see that now. I was just talking about the SSS for a spindle or the
like. I didn't look deeply enough at the Axxus board to see what they
had.

A normal parallel port (printer) board will not have any isolation.
Some custom "control" boards may have.
