Ruby Nozzle / Faster Prints & Better quality

Hi here and there :slight_smile: ,

I just replaced the original nozzle 0.4 with a 0.4 ruby nozzle.


In this microscope pictures you see that 0.4 is long gone after ~300 Grams of abrasive material.

Which is ultimately ruining your print results.

beforehand i learned how much abrasive filaments damage your nozzle.
HOW MUCH abrasive filaments damage your nozzle!

which explained my bad print results from the Cetus3D at the end. I was just about to replace the cetus3D MK2 nozzle when the (digital internal SteperDriver Load based) Endstop detection failed.

The Cetus3D themself went back to microswitches in the MK3 Version.

Some people pointed out that a ruby nozzle can damage your print-bed … be assured, you can damage it with a brass nozzle as well. If you damage your bed by crashing into it hardly there is no big difference which kind of nozzle you have. Just get it leveled out right … :slight_smile:

So you have to make sure that:
a) the nozzle has the correct size (Height), which i can tell for the nozzle i bought
b) if the nozzle is substantially longer, you have to change the setting of the printer (somewhere) to let it know the new height for the calibration process … I think it’s already solved somewhere here in the forum.
c) How to change the nozzle, i read as well here in the forum (search…) … it’s doable, just don’t use to much force at any point.

I am printing with it since about two days and i have:

  • better print results
  • less or no stringing
  • i can speed up the printing process by 200% without a noticeable loss of quality

Here are the setting of luban, which i like pretty much for functional parts. It never let me down.
Cura is nice for more complicated prints.

And here are the results:

This the nozzle, a bit overpriced (in general) but if it holds on:

You can buy a hardened Nozzle for way less money which has similar results.
Only difference should be ā€œnoā€ wear at the nozzle region at all on the ruby nozzle, for what i am willing to pay the price.

I will make. a followup at some time to sum up the experiences with that kind of nozzle.

Just to let you know,

greetings Makers …

I think the bigger problem people have had is the opposite - damaging the nozzle running into the bed.
Either way, just need to be careful.

What are you printing with? Nylon? Those speeds are amazing for PLA, really pushing it for PETG. I found that going anywhere near those speeds gave me some overshoot. I’m doing 100mm/sec now for travel, 50mm/sec print for PETG.

You probably need to tune your Linear Advance, which can be different at different speeds. If by ā€œovershootā€ you mean backlash, that needs to be handled differently. I can print everything that I’ve tried at 80mm/s on the original Linear Modules with very good results, it just requires tuning and dialing in the slicer settings. I use SuperSlicer, but I haven’t run tests on the new Linear Modules as of yet. I do luv their reduced DB level though. :wink:

My wife actually likes the noisy original ones, she’s a musician, thinks some of the sounds from some prints are ā€˜musical’. Mkay.

Currently i am printing my 3 to 5 year old PLA. Stored with no precautions at all. Different suppliers with a generic air humidity in my ā€œGarageā€ :slight_smile: depending on ow long i take a shower next to it, i can assure you PLA does not need drying at all … if it hasn’t been submerged in water.

Any news in here? I wanted to buy also a ruby nozzle , but there are not available at this moment.

Here are still 94 pieces available!!!

I use the Dyze Designs Tungsten Carbide nozzles, been printing Caron Fibre and other abrasives for 2 years on them along with ABS / PLA / PETG with no change in quality.

One thing i did notice is they must have either optimised the nozzle or fluked it but they don’t ooze very much or if they do it takes a fraction longer before the ooze apears so get very clean prints off them. Way better than Olsson Ruby IMHO.

Here you can also find the tungsten carbide nozzles.

They are made in Germany, here in the forum is also someone who uses you and is very satisfied with it !!!

I have also ordered one , but until now I still use the above Ruby nozzle, so can not make a statement about the tungsten carbide nozzle !!!
