The Mean Well NES-350-36 power supply is 9.65 A, and available for under $50 from China on eBay. Mean Well are a cut well above the unsafe crap usually sold on eBay; you'll find them sold by many serious Western electronic component distributors, and also by CNC-related shops (they actually have offices in Europe and the US). I can't guarantee that the one you buy on eBay is built to the same standard as the one you buy from Digi-Key for twice the money, but I've had good luck with this guy so far. The next model up is the NES-450-36 (at 12.5 A), but the price jumps quite a bit.danimal wrote:That brings me to my last question. I am having a hell of a time finding a quality power supply rated for 36V 10-15A. I know that is a little large considering that I will be running my motors at about 2.5A, and the Nema 17s are in parallel so their operational characteristics are harder to pin down. The power supplies that I am finding are either cheap Chinese made, or they are $5-700 and have way more features and capabilities than I could ever justify the expense. Does anyone have a line on some quality, simple supplies for this application that wont go up in smoke and take my system with it?
There is no fundamental difference between most PCI parallel port cards. All of them made in the last 10 years or so will implement every parallel port mode, so they should work just fine with the Gecko. That cable certainly exists -- I have one in my box-o-cables. Also, here, although they don't say how it's wired (should be one-to-one unless they say differently).danimal wrote:Now I am running into all kinds of questions as I try to set this up. First, I do not own anything with a DB25 connection. I found some PCI cards on newegg, but not really having used any of them I do not know what to look for in terms of reliability and having the capabilities that i need for the Gecko. Along with this, most of the cards that I am finding are female, the Gecko is female also so I need a long male to male DB25 cable and that seems not to exist outside of custom order land.
