z-Axis for 3D printer - CorEssentials

thingiverse

This is the belt-driven z-axis assembly of my CorEssentials project. This abstract provides a concise overview for those who want to incorporate a belt driven z-axis into their own project. In my build, I utilized a 16T pulley on the Motor for z-Axis and connected it to an 80T pulley using a 188mm GT2 closed loop belt. This configuration offers a 5:1 ratio (500 steps/mm at 16 µ-steps with 1.8° stepper). To construct one z-Drive unit, you will need: A Nema 17 Stepper Two GT2 20T Pulleys, 5mm bore One GT2 16T Pulley, 5mm bore One GT2 16T Toothed Idler, 3mm bore A d=3mm, L=15mm rod (for z-Idler) A d=5mm, L=40mm rod (for z-Drive) A GT2 closed loop belt (L=188mm) Two M5x6 Threaded inserts You can find the latest files on the GITHUB-page: https://github.com/MacNite/CorEssentials The 80T pulley is from the Voron, and you can learn more about the Voron here: https://github.com/VoronDesign/Voron-2
