Push Harder! Full Steel Ahead!

Set of parts made of Hardened Steel to replace the plastic Drive and Main Double Gears on a Bondtech Large Gears eXtruder :

• LGX;
• LGX Lite;
• LGX Lite Mirrored.

Recommended to feed Engineering grade thermoplastics.

To use our LGX extruders above our default recommendations:

• with thicker mounting plates;
• at higher environment temperatures;
• at higher stepper motor currents.

— Lubrication is mandatory —

These drive gears are made of hardened steel. Without lubrication they will wear your motor gear down.
Use a brush and the supplied lubricant to coat the drive gear teeth.

— Metal gears conduct heat —

To feed PLA or TPU (low Glass Transition Temperature materials)
keep the stepper motor cool (current at, or below, 0.5A).
