A Question to MARISS

Dear Mariss:

I�m in the last steps to run 2 plasma cutters.
1.- One with a Gecko drives G 201 / Indexer LPT from
Ability Systems Combo.
2.- The other with Gecko drives G 201A / Indexer
LPT from Ability Systems Combo.

I�m getting noise in the PC when the plasma is on,
through step and direction lines.

The PC signal is 4.82 volts, the external power supply
is 5.03 volts (this is the one it�s powering the
Geckos).
All the cables are shielded and grounded.

What would your advise be, in order to fix this noise
problem?

Best regard
Raul Lara
