Driver board for 4A + motors ?

[xairflyer]

Just wondering what sort of driver board would be needed to run motors requiring over 4 amps.

I can get my hands on some
CONTROL TECHNIQUES
TYPE N0 34MS312
4.6AMP/PHASE 0.5ohM/PHASE

And was wondering would they be worth getting for a larger project down the road.

Ditto. Gecko.

I'll buy them for my "real" machine. For now, I'll get by with EAS's Microstep bareboard and PIC 16F84 microcontrollers. (www.embeddedtronics.com)

My advice to those who haven't done it yet:
Buy the stepper drivers first.
Then the steppers to match the
amperage of the driver.
Finally the power supply.

AirX,

You don't need 4.7 amp motors. Stick with motors under 2 amps. Gecko's, while worth it, are $115.00 each. Best left for an aluminum machine that can make use of the power.

just MHO

I know I don't need them now, just had the opertunity to get a couple at the right price.

Any chance of rewiring them to a configuration using less current?
(Mine were like that. Luckily...)

If you're a electronic hands-on, microchip.com has appnotes for using their PIC controllers with MOSFETs/HEXFETs to drive steppers.
