What about the latency? Can it match the 1 to 4 kilohertz servo-thread loop I have used? It's no help that the 7i92 is out of stock on both Peters and Johns web pages. How long to source one of those critters? Or that what I think would be the next step up, as in skipping the db25 breakouts in favor of direct i/o is the 7i76E @ $200. So I guess I am stuck, drooling over the possibilities, but still using an old Dell I paid $75 for, with a single core P4 that burns 90 watts, and a 5i25, in a box that occupy's at least a cubic foot to run this lathe. There IS a limit to the relatively clean space under the drawers in this Sheldon cabinet, so the motor driver box I am building up from an old rusty box will have to live out where swarf will collect on top of it. I do like the ethernetted idea because theres little effect to moving the computer to a cleaner location, a most desirable condition. Sigh. And not helped that my giddyup got up and left me needing another nap this morning. But I think I can go cobble up some hole locations and get this stuff mounted yet today. > On 10/23/2016 1:46 PM, Gene Heskett wrote: > > On Sunday 23 October 2016 12:02:58 Roland Jollivet wrote: > >> By the way, while you guys are discussing SBC's, there's also the > >> UP board <http://www.up-board.org/> too, which is x86. > >> > >> Here's a fun video <https://www.youtube.com/watch?v=dPJiShBIPw8> on > >> it too.
