Z-belt drive for Ender 3 type printers

thingiverse

I have tried to design a simple belt drive system for the z-axis. If you want to do your testing without a lot of expense, just use the original z-axis motor and you can make it work, but the gantry will fall by gravity when the z-motor has no electrical voltage. That is why I have used a geared motor.He intentado diseñar un sencillo sistema de transmisión por correa para el eje z. Si quieres hacer tus pruebas sin mucho gasto, simplemente utiliza el motor original del eje z y podrás hacerlo funcionar, pero el pórtico caerá por gravedad cuando el motor z no tenga tensión eléctrica. Por eso he utilizado un motorreductor.BOM:2x M3 screw (20mm lenght)4x M3 screw (33mm lenght)4x M3 screw (25mm lenght)5x M5 screw (30mm lenght)4x M3 nut5x M5 locking nut5x idler pulley (bore: 5mm)1x 2GT-20T pulley (bore: 8mm)Belt 2GT 6mm1x Nema17 Geared stepper ratio: 5.18:1 Want to know more? visit my channel:https://www.youtube.com/@RogerThingsChannel
