LDO Galileo 2 Z Drive

The Galileo 2 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 and pulley themselves). 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 usermods outside of the V2/Micron printers, such as a belted V0 Z drive. Currently, G2Z is NOT recommended for large V2 printers if gantry sag is a concern; the G2Z modules will drop as much or more than the stock V2 Z drives on larger printers. That said, users have installed them on printers up to 350mm in size without additional issues over the noted gantry drop.

For those that are curious about what Galileo 2 offers over Galileo 1, here’s a short list of benefits:

  • Galileo 2 is a full redesign, moving to a 9:1 gear ratio and optimizing the gearbox design over Galileo 1. No parts from Galileo 1 are reused with Galileo 2.
  • Custom 9T stepper with a taller spur gear resulting in 20% higher contact surface area than existing 10T stepper designs, resulting in better wear characteristics and power transfer.
  • Proper meshing of gears due to number of stepper teeth being divisible by number of planets (9T sun / 3 planets), which gives even loading on the planets / sun gear and improves wear characteristics and power transfer. Previous designs with 10T steppers had uneven loading on the planet gears.
