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:
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
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
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.

Qual è la differenza tra un estrusore Single Drive e uno Dual Drive?
L'estrusore Single Drive utilizza un solo ingranaggio motorizzato e un cuscinetto a pressione. Il sistema Dual Drive utilizza due ingranaggi controrotanti che afferrano il filamento da entrambi i lati, garantendo una forza di spinta doppia e riducendo drasticamente lo slittamento, specialmente con filamenti tecnici o velocità elevate.
Quando dovrei sostituire l'ugello (nozzle)?
L'ugello va sostituito quando si notano problemi di stampa, specialmente superficiali, o se il diametro del foro si è allargato a causa dell'usura (comune con materiali abrasivi). Un ugello in ottone usato con fibra di carbonio può rovinarsi in poche ore di stampa, mentre uno in acciaio temprato può durare mesi.
Perché il mio estrusore scatta (fa rumore di "clic") durante la stampa?
Il rumore di scatto indica che il motore non riesce a spingere il filamento. Le cause, tra le altre, possono essere un ugello parzialmente ostruito, una temperatura di stampa troppo bassa, o una velocità di estrusione eccessiva per le capacità termiche del tuo hotend, un meccanismo non adeguato al tipo di filamento utilizzato.
