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 TEC-4.1 3D printer, e.g. filament settings and things to do with the extruder or slicers

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

• 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.
