The Bondtech LGX Steel Drive Train Upgrade 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

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 : between 0.3 and 2.3 mm;
Limited to 3.0 mm

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

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

On the LGX Lite and LGX Lite Mirrored
We recommended Max Environment operating temperature : 70°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
Rated current: 0.7A.
We recommended between ~0.45 and ~0.60A

On the LGX Lite and LGX Lite Mirrored
