G2 Z-Drive (G2Z) is designed as a compact Z-drive for the Voron V2 and Micron printers. It features the same 9:1 planetary gearbox and stepper in an easy-to-assemble package without the need for belts or pulleys (outside of the Z belt pulley). This design saves considerable space in the electronics compartment for small V2 printers, as well as the Micron 120 and 180 printers, allowing for more room where it's needed most. On larger V2 printers the benefit is smaller, but still includes the higher gear ratio (up to 9:1 from 5:1) for increased print resolution. There are also multiple applications for user mods outside of the V2/Micron printers, such as a belted V0 Z drive.
