Re: Olsson Ruby Nozzle for abrasive filiments
I'm using one - and have been for a while,
I print a fair amount of metalized (PLA) and carbon fiber filaments ...
Hi Mark
Very informative post thank you, but I have a follow-on question.
There are some members on this forum who have suggested that abrasive filaments also cause damage to the heat break over time.
May I ask as to your experience in this regard?
Many thanks in advance

Hi Peter,
I haven't noticed significant damage to the heat break to date (then again I try not to regularly strip down my hot end) so I guess my $0.05 worth would be, I haven't experienced any major issues with heat break wear.
What does need attention periodically is the extruder drive gear, but at least that is visible 🙂
Cheers....

Thanks, that was almost the answer I expected. 😉 Although you do tend to imply that like me, you haven't noticed any damage to the heat break...
Do you change the PTFE tubing at all?

again, I haven 't had to.
That said, I guess it's a perfectly reasonable thing to expect the abrasive filament to damage the heat brake and PTFE tube, but I just have not had to !?!!
If that changes I'll send an update 🙂
Re: Olsson Ruby Nozzle for abrasive filiments
I have been using the 0.6 mm and the 0.8 Ruby for a while now, printing mostly XT-CF, Copperfill etc (multiple kg's for your information). Haven't had any problems with the heatbreak/the nozzle so far. Works fenomenal en prints very good. Also the increase in temperature is not that high, 5 degrees C due to the base of the Ruby 🙂
Re: Olsson Ruby Nozzle for abrasive filiments
Hi, still very happy with the ruby... since it's the part that has the most contact with your filament and printed parts I would say it's THE most important part in your setup.... First buy your Ruby then build a printer around it....... calibrate, set and forget about layer hights... ever...
I have the 0,4 nozzle. It does seem that the pressure inside the nozzle is higher than when using the stock nozzle.
Can anyone share their best S3D extrusion settings :
Nozzle widht = ?
Extrusion multiplier = ?
Retraction = ?

Those settings should be fairly much irrelevant (being the same as the stock nozzle), but the retraction (pressure) will to an extent depend on the length of the nozzle bore. With E3D nozzles, the bore length is twice that of the diameter.
Peter
EDIT: I have now received a correction from E3D that in the case of nozzle sizes 0.25 to 0.4mm, the bore length is 1.5 times the diameter.

Re: Olsson Ruby Nozzle for abrasive filiments
Have you figured the settings out for hardened nozzles?
Re: Olsson Ruby Nozzle for abrasive filiments
I print only eng filaments, most cf and gf filled.
My experience shows that with higher temp the wear on hardened nozzle is minimal.
I print at 280-290c and so far see no point switching to ruby.
Most wear i see is on my extruder hobbed gear.
I'm also considering tungsten nozzle, rather than the ruby
