Re: Fw: [CAD_CAM_EDM_DRO] Re: PWM vs Constant current and G-rex

Jarret,

Yes, you'll need a power supply for whatever motors you decide to use and the Geckos use that same power to operate I think, not sure about that. They dont need their own external power supply to operate. . I'd invest alot of time reading and researching these forums and the internet. What type of machine are you wanting to retrofit and what type of motors are you wanting to use? The breakout referenced below is the same type that I use on all my machines and has given me excellent service.

Ron, I'd looked at the combo board on Mr. Chambell's site [ sound logic]
and had thought it was pretty pricy compared to other borads which do

much the same thing.. of course I was forgetting that this included power
supplies and a charge pump.. so after looking at it from that perspective..
I think it would end up cheaper.. plus its and all-in-one package so..
You'd still need power supplies for the Gecko's off downstream from this
though also.. won't you?
