Recommendations for Olsson ruby
Hi,
I'm new in 3D printing.
Yesterday I installed my Olsson ruby on my new MK3. But in comparison with the original nozzle, I get worse results. Under extrusion, extruder clicking and failing bridges.
The first layer looks exactly like with a brass nozzle. So I changed my settings. I reduced the fan speed by 5% and raised the nozzle temperature by 7°C.
It's better but not perfect.
Could you suggest some better settings or modifications for the Olsson ruby? Should I do a PID calibration (I have some temperature flickering)?
Thanks in advance
Peter

I must say that I've tested the Olsson Ruby (as well as steel nozzles) for I print a lot of abrasive filaments (metal, stone and wood filled) but didn't feel none of those did perform as well as a standard brass nozzle: temperatures had to be increased significantly and jamming occurs more often at lower feed rates than with brass nozzles because of inferior heat transfer to the very tip of the nozzle.
I went back to brass nozzles. Using a professional inspection & measurement microscope, no noticeable wear could be detected after printing a Kilogram of abrasive filaments. Brass nozzles are cheap anyway so just replace them more frequently if unsure.

Amen to that!
Dunno why you want to spend big bucks on a nozzle when cheap brass ones do the best job with all filaments. As you say, set up a change out regime based on hours and filament type. It aint rocket science. 😎
Of course, apologies to the op as it doesn't help with an answer 🙁

He certainly was angry. 😛

Great comments from Ander Olssen below, including a discussion on the proper torque. Sounds like E3D's recommendation is too high.

I'm sticking with hardened steel for abrasives and brass for general printing.

Ok, I don't know why, but I had to raise the extrusion for PLA by 4%. Now I have beautiful results with the OR. With PETG 100% extrusion works fine.
For both, I raised the nozzle temperature by 5°K.

I don't Don't necessarily agree with this angry dude, but it does require a bit of configuring. I have a mix bag of parts in my extruder including a Gold edition v6 with a copper block, PC/CF extruder body, silicone sock and titanium heatbreak. I didn't have to adjust temperature due to this. I did have to change my extrusion rate though. It seems that the diameter is larger than what was specified or it slipped through quality control. Either way.... I have ran it for about 5 months without a issue and probably killed about 6 rolls of chopped carbon fiber filaments ( most of them are PC/CF that I need to run at 295C). Never going back to hardened nozzles again 🙂
Re: Recommendations for Olsson ruby
I was wondering about steel vs brass myself... its kind of PITA to switch over the nozzle when using abrasive materials ...so
what are some common signs of a worn nozzle? does PET wear brass nozzles faster as well ?
I noticed im starting to get "globs" when my prints first start up... and first layers are harder to get to stick
Re: Recommendations for Olsson ruby
For those who do not know why people want to use the ruby nozzle instead of using one that will wear out and have to be changed regularly, think about what all is involved with changing out a nozzle and you have your answer.
I have one of the ruby nozzles, raised the temp by 5C and everything prints wonderfully. I do not have to worry about changing the nozzle because my prints are starting to suck, then doing all the calibration over again. Calibration sucks, hate doing it, and spending some money once to not have to do it over and over again is worth the price.
Besides, I HAVE the money to spend, so why not spend it to make my life easier and more enjoyable?

Firstly, I have thought, and done. It takes about 10-15 minutes to change out a nozzle, and as diy tasks go, it's pretty easy.
Second, while simple brass do wear out they do not wear as quickly as some people suggest.
Thirdly, you can pick up brass nozzles for less than a buck. The quality is no different than the more expensive brand.
Conclusion? Will never bother with a very expensive nozzle like the Ruby. There is little point, IMHO.

Good for you. Do you want some crackers to go along with your soup bowl full of arrogance?

Yes please, and perhaps some for yourself as well? As I said, IMHO. Perhaps grow up a little before coming to play in the big pen? 🙄

Your arrogance is still on full display. There was no reason for you to explain why I am wrong about my reasons for me using the ruby nozzle, but your arrogance required you to say you are right and I am wrong about my reasons for why I do something.
