LGX Steel Drive Train Upgrade Set

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
• LGX Lite V2

The LGX extruders fit very well most filament extrusion applications, but some cases demand additional features or capacity that cannot be enabled by their plastic gear sets. Those cases are:

• 1.When the LGX are used with a plate in between the extruder and the stepper motor thicker than our recommendation, and up to a limit.



On the LGX: Optimal Thickness is between 0.3 and 2.3 mm and Limited to 3.0 mm

On the LGX Lite and LGX Lite Mirrored: Optimal Thickness is 2.5 mm and Limited to 3.0 mm

Note: the LGX Lite V2 cannot be mounted with a plate between the extruder and the motor.

• 2. When the LGX is used in work environments warmer than our recommendation, and up to a limit.



On the LGX: We recommended Max Environment operating temperature : 70°C Limited to 90°C

On the LGX Lite, LGX Lite Mirrored and LGX Lite PRO: We recommended Max Environment operating temperature : 70°C Limited to 90°C

• 3. When the current fed to the LGX stepper motor is higher than our recommendation, and up to the 95% of the rated current.

On the LGX: Peak current is 0.7A and the max recommended current is 0.63A. We recommended between ~0.45 and ~0.60A

On the LGX Lite and LGX Lite Mirrored: Peak current is 1.0 A and the max recommended current is 0.7A. We recommended between ~0.45 and ~0.60A

Important to Know:

• 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).
