Linear motion

thingiverse

Need a straightforward motion solution? This thing offers a simple answer, powered by an extremely low-cost 24BYJ stepper motor. If needed, limit switches can be added. Stepper control is handled by an ATtiny85 and a ULN2003 driver. A little lubrication won't hurt anything. Rack and pinion components are based on the enclosed openSCAD script from Dr Joerg Janssen. A 20 cm rack length can be achieved by rotating the rack on the bed 45 degrees around the z-axis. https://youtu.be/2h2Gol47aHI
