LDO Galileo 2 Extruder

The LDO Galileo 2 Extruder is a high-performance extruder upgrade designed to elevate the 3D printing experience Designed and open sourced by JaredC01. This set includes the LDO Galileo 2 Extruder (G2 Extruder / G2E) and can also be used to build the Galileo Standalone Extruder (G2SA) offering versatility and precision for a wide range of 3D printing applications. The Galileo 2 Extruder features a robust design and enhanced filament control, ensuring reliable and consistent extrusion. With its high-quality construction and advanced features, this kit is suitable for both professional and enthusiast 3D printing setups.

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.

The LDO Galileo 2 Extruder Kit is compatible with various 3D printers and is an ideal choice for those seeking to upgrade their existing extruder or build a new 3D printer with advanced extrusion capabilities. Elevate your 3D printing experience with the LDO Galileo 2 Extruder Kit, designed to meet the demands of professional and enthusiast 3D printing applications.

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.

rotation_distance: 47.088
gear_ratio: 9:1
microsteps: 16
