The tool head is attached with three screws. The print surface can be damaged if the tool head is allowed to fall onto the print surface.
With one hand, support the tool head.
Using the 4mm driver, unscrew the three M5 screws securing the tool head to the X axis carriage.
Remove the bottom screw first, followed by the remaining two screws.
Install the 3mm screws from the underside of the extruder body with the 2.5mm driver. Torque to 6 in*lbs.
Caution: the extruder body can crack if there is too much torque applied to the mounting screws. Do not apply more than 6 in*lbs to the 2 M3x15mm screws.
Ensure that the Hexagon text is facing forward, with the thick red wires coming out of the right hand side of the block.
Press the repaired toolhead onto the X axis carriage, aligning the tab with the cutout on the back of the new tool head.
Secure it to the X axis carriage by loosely screwing in the top two screws. Leave the top two screws loose.
Install the last screw into the bottom of the X axis carriage and fully tighten.
Tighten the top two screws.
Verify everything is working properly:
Does your micro blower turn on when your 3D printer is powered on?
Do you get any errors when connecting through Cura?
