LGX Steel Drive Train Upgrade Set - Bondtech

Set of hardened steel parts to replace the plastic transmission and double main gears of an extruder Bondtech Large Gears eXtruder.

It can therefore be used for:

• LGX
• LGX Lite
• LGX Lite Mirrored

When to use the LGX Steel Drive Train upgrade from Bondtech?

• Recommended for the use of technical filaments
• Thicker mounting plates
• At higher ambient temperatures
• At higher stepper motor currents

NOTE BEFORE USE

• Lubrication is mandatory. These transmission gears are made of hardened steel. Without lubrication they lead to rapido wear on the motor gears. Use a brush and the supplied lubricant to coat the transmission gear teeth.
• Metal gears conduct heat. To extrude PLA or TPU (materials with a low glass transition temperature) control the stepper motor temperature while maintaining a current of 0.5A or less).

LGX extruders are very well suited to most filament extrusion applications, but in some cases they require additional features or capabilities that plastic gears do not allow.

These cases are:

1. When LGXs are used with a plate between the extruder and stepper motor that is thicker than recommended
   LGX: Optimum thickness: between 0.3 and 2.3 mm; Limit at 3.0 mm
   LGX Lite and LGX Lite Mirrored: Optimum thickness: 2.5 mm; Limit at 3.0 mm
2. When LGXs are used in hotter working environments than recommended
   LGX: Maximum ambient operating temperature: 70°C Limit to 90°C
   LGX Lite and LGX Lite Mirrored: Maximum recommended operating temperature: 70°C Limit at 90°C
3. When the current supplied to the LGX stepper motor is higher than the recommended current and up to 95% of the rated current.
   LGX: Rated current: 0.7A. A current between ~0.45 and ~0.60A is recommended.
   LGX Lite e LGX Lite Mirrored: Rated current: 1.0A. A current between ~0.45 and ~0.60A is recommended.
