I find that a bit hard to believe, that flipping switches will destroy
the board.
But, maybe they plugged it into the wrong kind of board slot, plugged
the wrong
connector in or something.

Not surprising.

Find out what the resolution of the encoders is. Figure out what
velocity you want to
see in rapid traverse mode. Then, figure out how many encoder counts per
second
that translates to. I think you will find it comes out to 100 KHz or
more, and may
be above Mach3's ability to produce pulses. So, then you may have to
either compromise
or get a hardware controller to output the pulses fast enough.
