Upgrade and Simplification Sep 2018

It turns out that the extruder motor mounts directly to carriage piece via rear screws on the motor using M3x30 screws with washers. Clam of carriage used 3 of the diagonam M6 bolts for closure, and 2 of the opposite diagonal bolts for attaching the extruder to the carriage.

CAD Generation

Build June 2018

MJ built this and it suffered from interference that stalls the blower fan. Fan must not be too close to the stepper motor.

Introduction

An open source extruder for regular and flexible filaments that can also be used with the Volcano heater block + nozzle for printing with volcano 0.6 mm to 1.2 mm nozzles.

Build Instructions

Bugs

  • Grub screw on pinion gear interferes with the second gear because the grub screw is not recessed. This requires more precise mounting of the pinion gear, and disallows usage of the extruder without a mount plate. A 2 mm spacer is needed for use with the standard D3D Extruder Holder.

Note that Titan Aero 3 mm extruder has 6 mm thread on both sides of heat break, while E3D v6 1.75 has 7 mm on cold side (for teflon) and 6 mm on the nozzle side. This is from the Lulzbot file:

Data Collection

  1. 5/16/20 - 2 of 6 Titan Aeros in printer cluster got stuck for no reason. Took it apart. No visible stuckage. After putting it back together, the filament went right through. Fault happened in both cases as brittle filament broke. In one case, pathway was free from any blockage. Filament just did not feed until extruder was disassembled. Suspected cause: misalignment between neck and heat sink.
