Need help to locate stepper motor control board plus driver

[Techbuilder]

Hi everyone

I have a small road block that has set course to my route,
maybe you can help to solve it.

I found the perfect stepper motors for my setup but
I can't seem to locate a circuit that will handle the amps.

Here's the motors

4: NEMA 34 HIGH TORQUE STEPPER MOTOR 640 oz-in, Shaft with a flat, 80 mm

KL34H280-45-4A (Single Shaft) Specification Price: $89 Rated Current: 4.5A, Rated Voltage: 4.1V

I wanted to use mach 3 as the cnc software

I want to build the stepper motor board to connect to my pc as well as the drivers.

any one know of any schematics that can handle my amps and can be used with mach 3?


Any help would be greatly appreciated

Hi,

Gecko 203V's will do the job. They're rated for 7amp per phase.
I have three on my CNC mill retrofit.
I bought them from www.homeshopcnc.com with my HT 1200ozin NEMA 34 steppers.

You can buy them direct from www.geckodrive.com too.
