Precautions

 

1. Brass (>59%Copper) or copper alloy (>95% Copper) are soft metals. They cannot withstand high torque, over-tightening it will likely break the nozzle body. It is recommended to install Durozzle nozzles with gentleness, apply just enough torque during installation to avoid destroying the part.

 

2. Ruby is very hard but also brittle. Hitting the nozzle tip with hard surface may shatter the ruby tip. After installation of nozzle, users always need to re-calibrate Nozzle Offset/Z-level/Nozzle Height value to avoid crashing the nozzle tip onto the build platform. As nozzle crashes is the major cause of death of ruby nozzles.

 

Installation

 

Step 1: Gather the necessary tools

Before you begin, make sure you have the following tools:

• Wrench or socket set
• Heat-resistant gloves
• Clean cloth or paper towel
• New 3D printer nozzle

 

Step 2: Heat up the printer and Unload filament

Unload filament before swapping nozzle. This could prevent material contaminating the threaded region of heater block. Heat up the existing nozzle to 180℃ to loosen it.

 

Step 3: Remove the old nozzle

Using the wrench or socket set, carefully loosen and remove the old nozzle from the hot end of the printer. Be cautious as the nozzle may still be hot. Use the heat-resistant gloves to protect your hands.

 

Step 4: Clean the hot end

Take the clean cloth or paper towel and gently wipe away any excess filament or debris from the hot end. This will ensure a clean surface for the new nozzle to be installed.

 

Step 5: Install the new nozzle

Take the new 3D printer nozzle and carefully screw it into the hot end. Use the wrench or socket set to tighten it securely, but be careful not to overtighten as this can damage the nozzle or hot end, follow common sense,stop tightening when you feel its tight.

If the heater cool down before installation of nozzle, user need to heat up the nozzle again and further tighten the nozzle while hot. This is import to prevent leakage.

 

***If you are not sure how much force to apply, please refer to the “torque recommendation section at the last section.

 

Step 6: Re-measure the Z-value/Nozzle Height

This is a very important step. The Z-value, very likely will change after switching to new nozzle. If you print directly using the old value, the print will either printed too high or nozzle will be too close to bed. Both cases in the worst scenario could be detrimental to the nozzle or the printer.

 

Some printers will do this before each print job (eg. BBL P1P, Creality K1 or other Klipper driven printers), while others may need to be done manuall

 

Remember to refer to your 3D printer manufacturer's documentation for any specific instructions or precautions related to your particular printer model.
