Features:
Compatible with flexible filament
Reduced stringing compared with bowden extruder
LDO HT motor, which is rated for 180℃ and allows for faster acceleration and direction change
Only ~150g weight, resulting in increased print speeds without sacrificing quality.
Glass fiber reinforced nylon injection molding parts instead of printed parts for housing, more robust/durable
DuPont Delrin injection molded gear, longer lifespan
Hardened steel dual drive gear provides bigger feeding force for filament
Recommend stepper current 0.35A RMS, don’t exceed 0.5A
What’s changed from v1
DuPont Delrin molded planetary gears
Glass fiber reinforced Nylon housing and latch
Filament guide part of the extruder housing
PTFE tube connector on top
New stepper motor LDO-36STH20-1004AHG – 20mm long with more torque
Some internal bearings dimensions has been changed to simplify assembly and improve the molding process quality
