Gecko Drives is working on a new stepper driver. Was due to be available early this year.
It's an INDEXING stepper drive but do not see it available yet.
All you would need is this one driver and a cheap power supply. (and the motor, of course)
It will be very configurable.
I've been anxiously awaiting it's release as I have an immediate need for several.
There are other commercially available Indexing stepper drives out there, but they are a bit pricey.
I use an older obsolete Parker OEM 010 and it does well, but, I wouldn't pay what they want for a new replacement model.
FWIW,
Russ
