Before proceeding, you should first assemble your E3D v6 All Metal HotEnd. Follow E3D's assembly guide. Stop at step 24. The steps after that will be completed as part of this guide.

Make sure that you have printed all of the necessary parts. We recommend printing the mount in either PETG or ABS due to the heat it may be exposed to.

Make sure that you have the necessary nuts and bolts. These are listed in the parts list above. If you don't have any on hand you may need to purchase them from McMaster-Carr.

If necessary, heat the hot end in order to remove any filament from the hot end and Bowden tubing. Take any spools off the spool holder.

Turn off the printer and unplug the power cord.

Follow our separate guide for flashing the bootloader on your printer.

If you are using one of our precompiled firmware images then you can flash the firmware through MatterControl.

If you do not already have MatterControl then download, install it, and choose the correct profile for your machine. Plug your printer in to the computer.

In MatterControl, make sure that the correct serial port is selected for your printer. Go to Settings & Controls > Settings > Printer > Connection and choose the port.

Go to Controls and scroll down to the bottom to find the Firmware Updates section. Click the Change button.

Select the .hex file you downloaded earlier.

MatterControl will now backup the original firmware (if it has not already been erased) and upload the new firmware. You can monitor the progress by going to View > Terminal.

When it is done your printer will reboot and show the splash screen for Marlin.

Unscrew the four M2 screws holding the layer cooling fan on.

Save the screws and the duct piece for later.

Remove the fabric tape around the end of the wire harness sheath.

Let the layer cooling fan dangle.

Unscrew the two M3 screws that hold the fan shroud on.

Cut the yellow and purple wires going to the heat sink fan.

Discard the fan and the shroud.

Remove the bowden tube by pushing the white collet ring down while pulling the tube up.

Cut the red wires going to the heater.

Cut the white wires going to the thermistor.

Unscrew the two M3 screws that hold the hot end on.

Discard the old hot end.

Use the soldering iron to press in the two M3 heat set inserts in the front of the base piece.

Use a knife to cut away any excess plastic that gets pushed out around the edge of the insert.

See our article for more information on how to use heat set inserts.

Press in the two M2 inserts in the side of the base piece.

Place the base piece on the carriage and screw it in place using three M3x6 screws.

Fit the new E3D hot end into the groove mount.

Orient the hot end so that the wires are coming out the left side.

Fit the clamp piece in place and screw it down using two M3x14 screws.

Check the end of the bowden tube and make sure that it is not plugged with plastic. Also ensure that the end is cut square.

If your bowden tube is worn, then you may consider replacing it with the new tube provided in your E3D kit.

Insert the tube into the new hot end. Make sure that it goes all the way in.

Put the blue locking clip in place under the black ring.

Use an M2x6 screw in the top right of the layer cooling fan to attach it to the mount.

Slide the duct onto the bottom of the fan and use another M2 screw to attach the bottom right side of the fan to the mount.

Use a third M2 screw and an M2 nut to hold the left side of the duct to the fan.

You can use a zip tie to hold the sheath out of the way while you work.

Take the two wires provided in your E3D kit and cut a 10 cm length from each. Use the end with the large connector.

Strip 2 cm from the ends of the wires.

Strip 2 cm from the ends of the yellow and purple wires that were connected to the original heat sink fan.

Cut two pieces of 3 cm long heat shrink tubing and slide them onto the yellow and purple wires.

Twist the yellow and purple wires to the red and black wires from a connector you prepared in the last step.

• Yellow goes to red.
• Purple goes to black.

Solder the connections.

Slide the heat shrink tubing down over the connections and use a heat gun to shrink it.

Repeat the process for the last step by soldering the other connector to the two white wires for the thermistor.

Cut the blue wires from the heater down so that they can easily connect to the red wires.

Solder the blue and red wires together using the same process as the last two steps.

Plug in the connectors for the thermistor and the heat sink fan. Make sure that the thermistor goes to the white wires and the layer cooling fan goes to the purple/yellow wires.

Slide the sheath down over the wires and wrap the end with the original fabric tape, if you still have it.

Secure the wire harness to the bowden tube using a zip tie.

Also use a zip tie on the hot end wires to organize them and hold them together.

Turn on the printer.

Check and make sure that the temperature reading for the hot end is accurate. It should be reading room temperature. If it reads 0, or a high number, then there is an electrical problem.

Check and make sure that the heat sink fan is running.

Set the hotend temperature to 270°C. Allow the hotend to reach 270°C and wait one minute to allow all components to equalise in temperature.

Use an adjustable wrench to hold the heater block in place while you tighten the nozzle using a 7 mm crescent wrench.

Set the hot end temperature to 0 and wait for it to cool off.

Fit the silicone sock over the heater block.

Follow our separate guide for running PID tuning.

Double check your bed leveling and adjust it if necessary.
