Here you will find all of the files for the Galileo 2 projects, including a Voron Stealthburner drop-in Extruder (G2E), Z-Drives (G2Z) for V2-style printers (including V2, Micron, etc.), and a Standalone Extruder (G2SA) with mounting options for Orbiter-2.0-style or Sherpa-Mini-style mounts.

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.

You must update both the gear_ratio and rotation_distance in your Klipper configuration and do a standard extruder calibration after installing the Galileo 2 Extruder. Additionally, your run_current will need to be updated.

You must update both the gear_ratio and rotation_distance in your Klipper configuration after installing the Galileo 2 Z Driver. Additionally, your run_current will need to be updated.
