RE: [CAD_CAM_EDM_DRO] Cables

I have been really happy with the Speakon connecters from Neutrik.

A bit pricey (cable end is $12, chassis end is $8 for eight connections) but
they are bulletproof, specifically designed for high-current applications
and about as indestructible as you can get. Twist-lock so they will not come
loose.

Comes in two, four and eight connections.

I use Parts Express for them:

I specifically went with these as I am planning several more CNC machines
(plasma cutting table and EDM sinker) and want the computer to be able to
control one at a time.

Good stuff...
