General Mach Discussion / Re: PC Locks up soon as CNC power is applied (LPT Port)

Welp.
Ive tried a known good PC, other cables, same result. Even lifted the earth ground from the chassis and no difference.
Would the idea of a voltage being backfed into the LPT port do it? Cause i have a CNC4PC board coming tomorrow. Im starting to suspect this ST-V3 board is junk.
