This is a derivative of Tinkering's http://www.thingiverse.com/thing:4526 with the endstop interface and the LED's removed (for now) using the http://www.robotshop.com/pololu-8v-35v-2a-single-bipolar-stepper-motor-driver-w-regulators.html .

I decided to make this guy because i fried one of my motor controllers by accident and the replacements have a 3 week lead time. Everything needed to make this can be picked up from radio shack in exception to some of the connectors. If you want micro-stepping (1/16), and want to learn how to make your own PCB, this thing is for you. Etching:
