z-Axis for 3D printer - CorEssentials

This is the belt-driven z-axis assembly of my CorEssentials project. This is just an abstract of the whole project for people who just want to use a belt driven z-axis in there project.

In my built I used a 16T pulley on the Motor for z-Axis and a 188mm GT2 glosed loop belt to connect it to the 80T pulley. This will give you a 5:1 ratio (500 steps/mm at 16 µ-steps with 1.8° stepper).

To built 1 z-Drive unit you will need:
1 Nema 17 Stepper
2 GT2 20T Pulley, 5mm bore
1 GT2 16T Pulley, 5mm bore
1 GT2 16T Toothed Idler, 3mm bore
1 d=3mm, L=15mm rod (for z-Idler)
1 d=5mm, L=40mm rod (for z-Drive)
1 GT2 closed loop belt (L=188mm)
2 M5x6 Threaded inserts
