This service document will outline the steps to replace the

hot-end assembly within the extruder, for the 3D20. This

guide should only be used if a replacement part has been

sent to you by Dremel customer service. The replacement

of the hot-end assembly may be needed if a clog occurs that

cannot be fixed with the unclog tool.

Tools Required:

The following list of equipment should be available prior to

the rework.

• 2.5mm Hex wrench (Allen key)

• Scissors

Step 1: Bring the printer to a safe state for

service

1. Cut any filament running into the extruder.

2. Run the load command from the filament screen. Allow

filament to run into the extruder for at least 5 seconds after

the end of the filament enters the extruder intake.

3. Exit the filament loading screen, and allow the printer to

reach a state where the icon reads “cool” on the screen.

4. Turn off and unplug the printer.

Step 2: Disconnect all electrical wires from

the extruder

1. Disconnect all four wires from the extruder, as pictured.

Always be sure to pull the connectors by the plastic, and

never by the wires. Pulling by the wires can damage the

onnectors.

Step 3: Remove the front fan and extruder

motor

1. Unscrew the two screws in front of the extruder fan using

the 2.5mm hex wrench.

2. Remove the front fan and heat sink, ensuring that the parts

attached to the screws do not fall. These parts can be

removed from the extruder as an assembly.

3. Remove the motor from the back of the extruder.

Step 4: Remove the turbo fan from the side of

the extruder

1. Remove the screw on the bottom left corner of the

extruder, as shown below. Removing this screw also

removes the fan baffle from the extruder.

2. Remove the back left screw from the extruder.

3. Pull the turbo fan away from the mounting carriage.

Step 5: Unscrew the hot-end assembly from

the mounting carriage

1. Remove the left and right hand screws from the bottom of

the extruder mounting carriage.

2. Remove the hot-end assembly from the mounting bracket.

Step 6: Replace the hot-end assembly

1. Place the new hot-end assembly on the mounting bracket.

2. Using the 2.5mm hex wrench, insert and tighten the 2

mounting screws into the bottom of the bracket (shown in

Step 5: 1) to attach the new hot-end assembly.

Step 7: Replace the extruder on the mounting

bracket

1. Taking the heat sink and fan assembly, place the front

mounting screws through the aluminum block. Place the

extruder motor on the back of the extruder and screw in

he two screws.

2. Reconnect the four wires to the extruder, as shown. Be

sure to properly manage the wires next to the extruder.

• The blue and orange wires connect to the two clear

wires on the extruder.

• The black and red wires connect to the black and red

wires on the extruder.

• The red and blue wires connect to the white and red

wires on the extruder.

• The long connector attaches to the motor on the

extruder.

Congratulations!
