Galileo 2

NOTE: Galileo 2 Extruder and G2Z/G2ZXL are currently at RELEASE status. G2SA is still PUBLIC BETA pending design finalization and testing.

Welcome everyone, to Galileo 2!

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.

Klipper Settings for G2 Extruders (G2E and G2SA)

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.

[extruder]
rotation_distance: 47.088
gear_ratio: 9:1
microsteps: 16

[tmc2209 extruder]
run_current: 0.6

Klipper Settings for G2 Z Drivers (G2Z)

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.

[stepper_z]
rotation_distance: 40
gear_ratio: 9:1
microsteps: 32

[tmc2209 stepper_z]
run_current: 0.8
