This 3D printer is an implementation of the Ultimaker 3D printer Using the Modular approach, many of the parts from the CubeSpawn 3 axis mill translate straight across into this design, so adding new concepts should go quicker

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?)

Small Form factor based 3 axis Gantry style mill, Removeable mechanical module. Removable Electronics. with a removable machine pallet, for automation.
