Linistepper V3We have closed out stock and are no longer supplying this kit. Documentation has been updated. Source code, layouts, etc... are all available if you want to make your own. If you would like to support a SMT layout / kit, please contact us.
The Linistepper is a well reviewed, open source controller / driver for small to medium sized 5, 6 or 8 wire unipolar (not 4 wire bi-polar) stepper motors. The Linistepper combines ultra smooth old school linear microstepping with modern active current regulation for faster response. The kit is easy to build, hard to damage, and easy (and cheap) to repair. Fully documented: how it works, how to use it, how to troubleshoot problems and get your motors running!
• Drive up to 3 amps* at 36 volts for over 100 watts of power: Enough to move a 15lb axis at 60IPS or a 30lb load at 30IPS!
* requires 2 sets of tuning resistors and a fan heatsink.
• Supported modes include:
• Standard: Full, and Half step,
• Full-Torque Half (!),
• Microstepping: 6th, 18th and infinite, analog-linear microstepping
• Standard step + direction inputs
• Easily connect up to 7 units to a parallel port
• Works with any standard CNC program such as Mach 3, TurboCNC, EMC2
• New version: V3
• moves power resistors to heatsink side for better cooling
• supports analog smoothing adjustment with optional trim pots
• Faster clock speed supports higher step pulse rates.

These well made kits are easy to assemble with your soldering iron. Hard to break, easy to repair (new drive transistor set less than $2), smooth and cheap! If you are driving up to 3 amps on low cost unipolar steppers, nothing beats a Linistepper.
