MK3S Cyclodal Extruder Mod  

MK3S Cyclodal Extruder Mod

I designed cycloidal extruder inspired by Prusa XL. (But Prusa change their extruder cycloidal gear box to planetary gear box)

This extruder is under development and under test.

I tested several gear ratio 16:1 to 5:1 and finally I selected 5:1 gear ratio.

Because Einsy RAMBO board is 8bit controller and it is very low performance.

E-STEP value is very sensitve and 8bit Einsy board can not control 0.9 deg nema14 stepper.

Einsy board is not recommend E-Step value is over 1000.

5:1 Gear ratio can control E-Step value under 1000. ( U-Step is 8 and E-Step is 700 )

When I finish development I'll open this project to Printables.

This extruder support mmu2s.
