Spark Concepts CNC xPRO Driver. A new GRBL compatible, all-in-one stepper driver board with 4 motor controllers for XYZ + 1 clone (or rotary!). Capable of powering your next build with an ATX PSU (or 12V 2 wire supply), and ready for wireless printing. Compatible with Arduino (wireless robots anyone?)

The OpenBuilds team has redefined the belt and pinion concept. By using standard OpenBuild components were able to improve on this system in ways that will save on cost and enhance its engineering capabilities.

Example model of lead screw driven actuators for your next project!
