This Belt and Pinion actuator is a great example of how easy it is to convert your machine into a belt drive system.

The aim of this design is to build a simple, cost effective (under $1000) and relatively compact large volume (m3) 3D printer that will use a pellet extruder to create art/design objects using shredded recycled plastics.

This small desktop machine is built inside a 300mm cube of 20mm extrusion. Work area is 14cm by 14cm. I used 400 step nema17 motors all around.

Very cheap CNC made from laser fired and bent parts.

An OX-inspired mini desktop mill.

This is a WorkBee 1000x1000mm with lead screws and Nema17's. It has a reduced footprint, with the geared Nema's inside the frame.

The Acro Laser Machine Build

I built a motion control camera slider with the V-Slot® NEMA 17 Linear Actuator Bundle (Belt Driven)
