Various stepper drives
Here's a random collection of pics. I appreciate that there's almost no detail here.E-Mail me if you'd like to know more.
Over the years I've built a fair few stepepr drives, I'll attempt to chronicle some of them here

A very early 2 axis unipolar drive

A microstepping 3 axis drive based on the Allegro 3977 IC

A batch of cases with cnc machined panels.

For those of you using my latest effort, the manual and sample mach3 config file can be downloaded here
More to come...
