Re: Vexta Steppers / gearheads help needed........

Hi Mike,

Sounds like you've got as much info as I got with my motors/boxes. I
was guessing that the ratio was probably 7.5:1 from the part #, and from
playing with the gear head (one gear, meshes with motor's pinion), but
didn't want to give you just a guess.

With 6 wires, they'd be easy to drive with the Centent drivers (by
Mariss) I've just bought at auction. So with a little PS/Driver
building, I would have 4 axis of microstep, and gear reduced drives.
Now I need an application!

What's your application?
