Let’s turn your Ultimaker 2 into an Ultimaker 2+ with the Extrusion upgrade kit
You'll be finished in about an hour.
Before you begin, make sure the power is off and the power cable is unplugged.
First remove the cable cover on the back left corner of the Ultimaker
by removing the screws on the left and back part of the frame.
Ensure the build plate is positioned at the bottom of the Ultimaker when removing the cover.
Gently raise the build plate for easier access during the next steps,
then place the Ultimaker on its right side.
Remove the electronics cover on the bottom of the Ultimaker by removing the two screws.
Use the hex key to remove the screws on the inside of the Ultimaker
and use a socket wrench to hold the lock nuts on the outside.
Loosen the main board from the Ultimaker by removing the four screws and spacers.
You can reach the screws from the inside of the Ultimaker.
Remove the heater wires from the screw terminal HEATER1 using a flat screwdriver.
Disconnect the hot end fan from the middle of the board.
Disconnect the feeder motor from E1 on the main board.
Also, make sure you remove the ferrite core from the motor cables.
Next, disconnect the PT100 sensor from TEMP1.
Then disconnect the print head fans from FAN PWM.
Slowly guide the print head and feeder motor cables through the hole in the back left corner.
You can now place the Ultimaker back into the upright position and start taking out the feeder.
Hold onto the feeder motor on the inside to prevent it from falling down.
Take the new feeder motor and apply grease to the gear.
Attach the new feeder motor onto the frame with the feeder mounting plate
by using the new 10mm screws and the washers from the old feeder.
You can now attach the feeder to the feeder mounting plate by using two 10mm screws and the M3 rings.
The next step is to replace the build plate clamps.
Before you do, make sure the glass plate is removed.
Remove the screw at the front left with the hex key.
While you’re doing this hold onto the corresponding build plate screw at the bottom of the build plate.
Replace the build plate clamp with the new one and fix it in place with the screws.
Do the same at the front right side.
Take the axle tools and place them on either side of the left sliding block.
You can now pop out the print head shaft.
Repeat these steps for the other three sliding blocks.
For the ones at the back and front side, you have to push the shafts down instead of pulling them up.
Now turn the sliding blocks away from the print head so you can take the print head out of the Ultimaker.
Take the new print head and guide the new shafts through it.
The long shaft goes in from left to right and the short one from front to back.
Place the new print head in the Ultimaker and position it in the sliding blocks.
Use the axle tools again around the axles and push the shafts into the sliding blocks.
Put the Bowden tube in the feeder and place the clamp clip around it to secure it.
Place the Ultimaker on its right side again
and feed the cables through the hole in the back left corner towards the bottom of the Ultimaker.
All the new cables can now be connected to the main board.
Connect the blue­-orange wire to the connector on the middle of the main board.
Connect to PT100 sensor to TEMP1.
Connect the yellow­-green wire to FAN PWM.
Connect the feeder motor to E1
and place the ferrite core around the motor wires of the Y motor and feeder motor.
Connect the wires of the heater cartridge to the screw terminal HEATER1 by using the flat screwdriver.
Attach the main board to the bottom of the Ultimaker with the four screws and spacers.
After this you can place the electronics cover back in its position.
Be careful not to trap any wires between the main board, electronics cover and frame.
Position the Ultimaker upright and place the cable cover on the back left corner.
Use the screws you removed earlier to attach it.
To ensure your prints are perfect, you need to align the axles.
Start by loosening the 2 pulleys on the back X axle.
Place the print head align tools on each side of the back X axle
and once the grub screws of the pulleys are visible, click the print head shaft in the align tools.
Now push the pulleys towards the frame and tighten the grub screw with the hex wrench.
Repeat these steps for the two pulleys on the left Y axle
And insert the new spool holder.
To finish, upgrade your Ultimaker 2+ or Ultimaker 2 Extended+
with the relevant firmware and re-­level your build plate.
That’s it. You’re done.
Well, there is one last vital step.
Congratulations, you’re now the proud owner of an Ultimaker 2+
that will print even smoother, faster and more efficiently.
