FELIX 2.0: Updated extruder

Post by gfeliksdal »

Dear all,

After using the Felix 1.5 extruder for some time, in the long run some issues came to the surface. With feedback from some users we've made an incremental update to the extruder design.

Possible issues with Felix 1.5 extruder.
  • Extruder arm cracked after a while
  • Extruder base pt4 showed some cracks after a while
  • Hot-end was not completely fixed in carriage.
  • Filament guiding was too weak and could wear out after a while.
We did the following to solve the above problems.
  • Added some extra material where parts showed cracks especially on extru_base_pt2
  • Beefed up the extruder arm
  • Gave extruder arm more room to build up tension, results in better gripping of filament.
  • Put a notch on the extru_base_pt4, prevent hot-end from rotating.
  • Increased the height of slot on extru_base where the hot-end is inserted.
  • Added room to insert bowden guiding tube.
You can download it here.

Time will tell if all issues will be solved.

Don't hesitate to tell us your findings/tips/comments.

My firefox opens the gcode file as text so I can't save it. Can you post a rar-file?

Hi angryangel,

I got my kit on 6th may with the "old" one... Compare your filament intake feature with the picture at the beginning of this post. If yours is smaller you have the "old" one...

@gfeliksdal

Is it possible to separate the parts of your .gcode file? I have problem to print more than 2 hours and I think the new extruder design could solve some of the problems.

Thank you very much

Benjamin
