Here, finally, is the upgrade/replacement to the Galileo 1 Extruder! We have both the G2E a Voron Stealthburner drop-in Extruder and G2Z (G2ZXL) Z-Drives for V2-style printers (including V2, Micron, etc.).

From the official GitHub project page:

• 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.
• G2XL uses Nema17 (LDO-42STH40-1684AC) which are considerably larger and provide more holding torque
