Project Description[edit | edit source]

This project involves the conversion of a single-extruder JellyBox to a dual-extruder JellyBox. Both versions of the JellyBox are reasonably compatible, with the only significant difference being the build plate size (which is a minimal difference).

Instructions for the ENGR 442 Dual Extrusion Modification[edit | edit source]

This modified version has been created in partial completion of the ENGR 442 class at Principia College. This version is designed for a JellyBox 2 modified for dual extrusion with one Bowden-style extruder and one direct drive extruder. The 3D file can be found on the Appropedia page which corresponds to this design.

Required Components[edit | edit source]

  • JellyBox
  • Chimera + E3D MatterHackers
  • Additional NEMA motor
  • New machine profile instructions below
  • Bowden extruder
  • Mount for Bowden (we used two zip-ties)
  • Firmware (this is designed for a 1.0 but modifying build volume makes it appropriate for a 2.0)
  • PTFE Tubing (we used Capricorn tubing)

Creating the New Machine Profile in the Slicer =[edit | edit source]

Create a machine profile with the following values using a custom FFF in CURA:

Slicer Profile Values for JB 1.0
Setting Value
X (Width) 180 mm
Y (depth) 165 mm
Z (height) 145 mm
Build Plate Shape Rectangular
G-Code Flavor Marlin
X min 0 mm
Y min 0 mm
Z min 0 mm
X max 0 mm
Y max 0 mm
Gantry Height 145 mm
Number of Extruders 2
Start G-Code Copy and Paste from the Jellybox2.0 profile
End G-Code Copy and Paste from the Jellybox2.0 profile

The firmware is hosted on Github and is under active development. Instructions are duplicated on Github and both pages link to one another.
