Felix Pro 2 3D printer

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

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.

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.

Printing with a 0.7 mm nozzle

Read:

• Speed & Max Flow Tuning from Teaching Tech 3D

Summary: Much more heat, disable filament detection, slow down

Printing with PETG

• Layer size = 0.56
• Extrusion = 100%
• PETG can roughly be printed between 230-260 degrees and , try a max. with a 0.7mm nozzle
• Take retraction away if you print fast, but normally it should be around 2-3mm and slow
• Remove filament detection if necessary, i.e. send the following g-code in the print manager or in the very end of the start code: M602 S0 P1
• Add banging floors into the wall (e.g. 50%)
• Infill 20% hexadecimal or some other that works well with higher speed.

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.

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
