Intro
This is an experimental stepper-gearbox for a direct drive extruder.
Project target
- Use a small, lightweight and powerful NEMA8/NEMA11-stepper to drive a filament drive gear (like MK8 or others)
- Minimize gearbox package through choosing a cycloidal drive system (gearbox ratio: something between 36:1 and 10:1)
- Setup a potential alternative to the outphased NMB PG35L-048
v0.1
Objective
Quickly check general feasibility using some existing components:
- Pololu NEMA 8 Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase, 180 g-cm
- StepperOnline Nema 8 Bipolar 0.6A 4Ncm(5.7oz.in) mini stepper motor 8HS15-0604S
- MK8 Drive Gear
- E3D v6 HotEnd - 3mm Direct (12v)
