1 Introduction

Felix Pro 1 acquired by DKS, TECFA, University of Geneva, delivered in Dec 2015

The Felix Pro 2 is a 3D printer made by FELIXprinters and that started shipping in December 201?. It features auto-calibration of the print bed, a dual head, etc. and strong, reliable steel extruders. Our machine was upgraded from the Pro 1 to a Pro 2. Print quality seems to be better.

This article will only include new information with respect to Felix Pro 1 3D printer, e.g. filament settings and things to do with the extruder or slicers

2 Ultimaker Cura Slicer

We do not recommend using the Cura slicer installed within RepèetierHost (both the one that is distributed by Felix and the original one), since it is a very old 3.x version.

As of dec 2020, use Cura 4.8. A Felix Pro 2 profile is already included.


3 Clearning the drive gear

  • Extruder jammin" could mean that are is some debris in the extruder, i.e. the drive gear

Disassembling is a lot of work, try the following first:

  • Open flap in front
  • Take out hot-end
  • Look from the bottom into the extruder, you will see the toothed drive_gear.
  • Use a tweezer to clean out the teeth. It takes a little time, but saves you the hassle of disassembly.

4 Printing with a 0.7 mm nozzle

  • More extrusions, more heat, disable filament detection

Printing with PETG

  • Layer size = 0.7
  • Extrusion = 100%
  • PETG can roughly be printed between 230-260 degrees and , try 240-250 with a 0.7mm nozzle
  • Take retraction away if you print fast
  • Remove filament detection, i.e. send the following g-code in the startup script: M602 S0 P1
  • Add banging floors into the wall (e.g. 50%)
  • Infill 20% hexadecimal or some other that works well with higher speed.

4.1 Cura settings for printing Duplo compatible blocks

Surprisingly, printing lego and duplo compatible blocks is quite a challenge, in particular with respect to overhangs not completing and nozzle getting stuck.

4.2 PLA standard for à 0.7mm nozzle

We did managed to print with 0.7mm layers, but 0.56 can be printed a bit faster and is more solid. 0.7mm layers also require higher temperature and disabling of the filament detector.

Quality
  • layer height = 0.56
  • line Width = 0.7
  • Inner line width = 0.7
  • initial layer width : 100%
Shell
  • Wall line count = 2
  • bottom layers = 1
  • Print thin walls = ticked (no necessary for duplo, but for Lego compatibles
Material
  • Printing temperature : 210
  • printing temperature initial layer : 210
  • initial printing temperature : 210
  • final printing temperature : 210
Speed
  • Print Speed = 40 (vitesse par défaut)
  • Infill Speed = 30 or 40
  • Initial layer speed = 10 (important !!!)
  • Wall speeds = 30
  • Initial layer travel speed = 20
  • skirt/brim speed = 10
Infill
  • "Infill before walls" = no
Material
  • Flow = 100
  • Wall flow = 100 (can be a bit less, e.g. 95)
Cooling
  • Fan at 50% or 0%. Better, turn the fan on for most parts and then off for larger flat sections. A comprise would be fan at 50% all the time.
Support
  • Aucun
Build Plate Adhesion
  • None with some glue on the plate or 4 lignes of skirt at 0 distance
