Build a Complete Cycloidal Extruder for 3D Printer

This shows how to make a complete cycloidal extruder that can actually be used in a 3D printer.

It took me a lot of time to design, make and test before and after. I have also used this to print many models. In order to let everyone pay more attention to and understand this extruder, you can enter this FB group: https://www.facebook.com/groups/3202068370116874

12 Spring 0.8x615mm;

13 Nema17 Stepper Motor;

14 big gear;

15 stainless steel pipe 3x0.5(wall thickness) ;

1 screw can not be overturned;

2 Flange Ball Bearing 8x12x3.5mm;

1Extrusion gear fitted with 5X11X5mm bearing;

2 Motor shaft notch to the left;

1 Make sure that the motor shaft cannot move;

2 Use Flange Ball Bearing 8x12x3.5mm;

you must pay attention to the direction of the cycloidal disc assembly, otherwise it cannot be assembled, please follow the video prompts.

Also pay attention to the direction signs

1 Press the Flanged Ball Bearing 5x11x5mm first;

2 Cover the ring pins and tighten it with M3X18mm screws;

Stainless Steel Tube Size: 3x0.5(wall thickness) 11mm long;

1 Use M3X18mm screws;

2 Here I use a top cover made of 4mm carbon fiber board;

Use M3X18mm screws

Here I use the same spring and screw as the Orbiter V1.5

Screw in the Mini Pneumatic Connector directly, you need a wrench.
