"dumb" stepper control

[ihavenofish]

i have an application for a stepper thats extremely basic, and i dont want to use an axis from mach to run it.

i need a stepper with 600ozin, and on a command from mach, it needs to rotate once and hold. then on a second command (either repeated or second input) it needs to rotate back to its original position and hold. it only needs to rotate at about 60-100rpm and full step mode is quite adequate.

i assume i need to run a drive (like a gecko g251 maybe) and then some sort of pulse generator. anyone know of something like this that can be bought? maybe some little programable board with configurable io?

merci

thats a neat little thing, might do exactly the trick by the look. but how much does it cost? the device im making isnt intended to cost very much.

ahh, its obsolete. wonder what the replacement is.

this ones interesting. driver and indexer in one. "regular" price is a bit much though as i cant exactly budget in one time surplus deals.

I could sell this one to you, I'm not using it ....really It's pretty handy to have around though. ( I have a bunch of Compumotor S6 and S8 drives and motors doing "various things around the shop".) Documentation is available on line. I have some down loads, and links.
Let me know if you need more fuel for the fire.


ps
$150 seems the going rate for the unit.

cool, but what i need has to be "new" and readily available and supported. $150 is also much too expensive i think.

Good luck!

A simple 555 timer would work to supply the pulse, the details will consume a lot of resources however.

a small PIC and a few lines of code would do it.

thanks, thats actually what a friend suggested, except hes going to try an arduino board which is like $35 and expandable when i add some more features.
