DIY driver/controller boards that work with emc. =


L297/L298 stepper driver ==
A single-sided board based on the L297/L298 chipset. up to 46V supply, 2A/motor, constant-current chopper. For bipolar motors. Half- or full-stepping with step and direction inputs. Eagle and PDF formats. Thru-hole components. http://pminmo.com/l297-8/l297-8.htm

Toy designs =


Low-current stepper driver ==
A single-sided board based on the ULN2803 darlington chip. Simple, but very low current, <500mA/motor. Not recommended for anything but a toy. Half- or full-stepping with 4 winding activation signals per axis. PNG images of schematic and board. http://axis.unpythonic.net/etchcnc

This could be adapted to a 3-axis design, because there are 12 available outputs.

L298 servo driver



A single sided board based on the L298 H-bridge. Up to 46V supply, 2A/motor. For DC servo motors with TTL-level encoder outputs. Driven by PWM input. Not recommended for anything but a toy. PNG images of schematic. http://emergent.unpythonic.net/projects/01142347802

This cannot easily be adapted to a 3-axis design, because each axis reqires 2 outputs and 2 inputs, but there are only 5 available inputs on the PC parallel port.
