Unplug the USB cable (if installed).

Turn off printer and unplug cables

6 Replace Bed Corners

Remove the four original 3D printed bed corner fingers using a 2.5 mm hex key.

The recessed side of the bed fingers should be facing up.

Remove original bed corners and screw in low profile bed corners

7 Remove Existing Tool Head

Unplug the tool head connector from the wiring harness.

Be sure to support the tool head with your hand to prevent it from falling onto the print surface.

Unscrew the tool head mounting screw by turning counter-clockwise from the X-axis carriage with your 2.5 mm hex key. Keep the screw nearby.

Note: In previous versions of our tool heads, the Esteps were listed along the back of the tool heads for the customer to update. For the new Aerostruder tool head however, the Esteps are now set up within the firmware, and no manual updates are required.

10 Remove Pins & Plug in Tool Head

The LulzBot TAZ 5 tool head harness connector (v2C) includes two guide pins used to prevent the standard tool head from being plugged in backwards.

You will need to remove these two pins from the tool head harness connector. Follow this guide to remove these two guide pins.

Plug in the Aerostruder, while making sure that the red, green, white, and black wires on both connectors are on the left hand side. Mark the side of the connector on the TAZ 5 harness that aligns with the arrow on the Aerostruder Tool Head harness. The guide pins can be retained as spares.

Pull foam off of 16-pin connector piece.

Find the side of the connector piece that has a small arrow and align it with the same side on the other connection piece.

Connect the two 16-pin connectors, making sure to match them based on the pins in the connector.
