How to change the nozzle on my DyzEnd or DyzEnd-X Hotend ?

Do not try to change your nozzle while the hotend is installed. Always remove it from your printer before changing your nozzle.

Step 1: Use a Wrench

Install the hotend in an adjustable wrench.

Step 2: Unscrew the nozzle

Unscrew the nozzle using an 8mm wrench. Avoid using an adjustable wrench for the nozzle. This tool isn’t optimal and risks damaging the nozzle.

If the nozzle seems stuck in the heat block, heat the hotend at half the printing temperature. While sealing, the washer let a little bit of plastic around its perimeter, making it hard to unstuck with certain plastics.

Step 3: Check if the parts are clean

  • Check inside the heat block, the bottom should be clean.
  • Check your nozzle, the sealing washer should be clean.

If any of these two parts have plastic on it, make sure to clean them before changing the nozzle to avoid any leaks. Refer to our “Cleaning” section regarding this topic.

Step 4: Insert a filament

Insert a filament inside the thermal barrier as a guide.

Step 5: Slide the sealing washer

Slide the sealing washer inside the filament so that the smallest diameter of the washer is in contact with the thermal barrier and the larger diameter is in contact with the nozzle.

Step 6: HandTight the nozzle

Screw the nozzle while ensuring that the filament is inserted inside the nozzle hole.

Make sure to align the heatblock as it was originally before tightening it.

Step 7: Tight the nozzle

Tighten using a 8mm wrench until the washer is flattened and until the nozzle is stuck and becomes difficult to tighten more.
