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.
