Re: [CAD_CAM_EDM_DRO] Can my CNC controller blow my motherboard?

You asked, "Can I buy something to protect the parallel port in case there
is something that can come back to kill it? Is there an optically isolated
parallel port card or something that could protect me? "

You may want to try the break-out board that I sell www.campbelldesigns.com
. The board uses optical isolators on all lines.
