THE OLSSON RUBY
INSTRUCTIONS
Thank you for purchasing the Olsson Ruby Nozzle! The Olsson Ruby was made to be extra durable for printing abrasive materials but has proven to work excellently with any material. And while the ruby tip of the nozzle is extremely wear resistant, there are a couple of things you should keep in mind to make sure your nozzle stays in perfect condition.
Installation
If you do not have a torque driver we recommend using The Olsson Nozzle Tool, which is designed to apply optimal torque for the nozzle to fasten properly without getting damaged. The design of the Olsson Ruby is quite intricate which makes it more sensitive to over-tightening than a standard brass nozzle.
If you do not have our nozzle tool we recommend using a torque driver set to 0.5Nm or download and print the Torque wrench by Anders Olsson.
USE THE PRINTED TORQUE WRENCH
ALWAYS CHANGE NOZZLES HOT
Always make sure that the heater block is heated up to printing temperature when installing or removing the nozzle. Cold plastic in the threads acts like a very strong adhesive which means you will need to use excessive force to unscrew the nozzle which can damage it.
When installing the nozzle, cold plastic can prevent you from getting the nozzle screwed in all the way which can lead to leaks.
Care
If you keep these simple precautions in mind, the Olsson Ruby will serve you well for a long long time. Whether you're printing with abrasive specialty filaments such as Colorfabb's XT-CF20, or just plain old PLA, we're confident you will be happy with this nozzle.
DO NOT EXPOSE TO IMPACTS
Be careful not to drop the nozzle on hard surfaces. The ruby ​​tip is very hard but can chip if it gets hit sharply.
Also make sure that you do not let the nozzle hit the glass retaining clips.
Cleaning
If you keep these simple precautions in mind, the Olsson Ruby will serve you well for a long long time. Whether you're printing with abrasive specialty filaments such as Colorfabb's XT-CF20, or just plain old PLA, we're confident you will be happy with this nozzle.
CLEANING THE OUTSIDE
If you need to clean the outside of the nozzle you can use a piece of cotton / linen cloth or a paper towel while the nozzle is hot. Be careful not to burn your fingers.
If that is not enough you can step up to steel wool to get stubborn burnt plastic off.
Do not use scotch brite pads to clean the nozzle as it will scratch the outer part of the nozzle. This is due to the rough side of these sponges being made out of aluminum oxide, the same material as Rubies.
Do not use a wire brush when cleaning the nozzle. One of the strands may get lodged in the orifice and crack the ruby.
REMOVING CLOGS
To clean the inside of the nozzle, always start by using the Atomic Method / Cold Pull. This will almost always be enough, and is the least potentially harmful method for clearing a clog.
Never attempt a cold pull outside of the printer, the nozzle needs to have the back flange supported while you apply the large pulling force, doing this without the support of the heat break may cause the nozzle parts to separate.
If several of these have not cleared the clog, you can upgrade to trying acupuncture needle. However, it is important that you do not bend the needle heavily while using it as this can destroy the ruby.
Do not use a flame to burn out residues from a nozzle as a way of cleaning them.
