RE: [CAD_CAM_EDM_DRO] Re: Question:Parallel interface with Gecko 201 drivers

Glad you have not gotten around my machines to tell them how their wires
must me. The parallel cables I have used and the ones I have cut apart
(cheapest I can find in both cases) are not twisted pair at all.

You are taking some best practices guidelines and solid solutions IF you
have noise problems and trying to make it the requirements for wiring.
In most cases it just ain't that critical.
