- A3967 driver configured for 8-microstep mode
I've been working tonight at lifting the mode pins from the PCB to allow control over the stepper mode so that I can use the various modes.

Before buying an MC3479 IC, are there any alternatives that are similar?
I may as well try and use something in my junk pile rather than buy
this IC if I'can avoid it.

Hi Bob, Steve,
were you able to use the A3967 or other alternatives with the bartels system? if so could you please post some info on how you did this with respect to the bartels system,
I'm trying to use the A4983 stepper driver from Allegro with the Bartels system and could do with some leads. Bojan mentioned there was a yahoo groups site that expained this, but have'nt been able to find it as yet.
Note on the A4983, you might want to give this a look as its an improved version of the A3967 and supports 1/16th microstepping and is very smooth. available in aus.

i've used it very successfully with a picaxe mcu to drive a stepper.
