Step 2: REMOVE THE FAN SHROUD

Pull the magnetic fan shroud off of the print head.

Set the fan shroud on top of the aluminum extrusion.

Leave the connector attached to the breakout board.

[Image Description: The magnetic fan shroud is shown being detached from the print head. An arrow indicates pulling the shroud away. The shroud is then placed on the aluminum extrusion, with its connector still attached.]

Step 3: DETACH THE FAN

Remove the two screws securing the cooling fan to the heatsink (2.5mm Allen wrench).

Set the fan on top of the print head.

Leave the fan connector attached to the breakout board.

[Image Description: The cooling fan is shown being detached from the heatsink using a 2.5mm Allen wrench. The fan is placed on the print head, with its connector remaining attached.]

Step 4: UNFASTEN THE ORIGINAL HOTEND

Remove the two screws from the top left side of the heatsink (2.5mm Allen wrench).

Remove the screw located on the front of the heatsink (2.0mm Allen wrench).

[Image Description: The original hotend is shown attached to the print head carriage. Screws securing the heatsink are highlighted, indicating removal with 2.5mm and 2.0mm Allen wrenches.]

Step 5: DISCONNECT THE CABLES

Disconnect the original hotend's thermistor and heater cables from the breakout board.

[Image Description: Close-up view of the breakout board on the print head. The thermistor and heater cables of the original hotend are shown being unplugged.]

Step 6: FASTEN THE FLOWTECH HOTEND

Attach the FlowTech hotend to the carriage using the three original screws.

Use the (M2.5 x 30mm) screw in the front of the heatsink and two (M3 x 16mm) screws in the top left side of the heatsink.

[Image Description: The new Micro Swiss FlowTech hotend is shown being mounted onto the print head carriage. The locations for the three mounting screws (one M2.5x30mm and two M3x16mm) are indicated.]

Step 7: CONNECT THE FLOWTECH HOTEND

Connect the FlowTech hotend's heater and thermistor cables to the matching ports on the breakout board.

Step 8: ATTACH THE FAN

Attach the cooling fan to the FlowTech heatsink using the two original screws (2.5mm Allen wrench).

Use the two (M2.5 x 18mm) screws.

[Image Description: The cooling fan is shown being reattached to the heatsink of the new FlowTech hotend using two M2.5 x 18mm screws and a 2.5mm Allen wrench.]

Step 9: INSTALL THE FAN SHROUD

Tuck the cables in so that they do not get in the way of the fan shroud.

Reinstall the magnetic fan shroud.

[Image Description: The fan shroud is shown being placed back onto the print head. Cables are tucked neatly to avoid obstruction. An arrow indicates the direction of placement.]

Step 10: CALIBRATE

Connect the power cable.

Power on the 3D printer.

Navigate the printer screen menus to "Leveling" and then select "Calibrate Zoffset".

Wait for the calibration process to complete.

Installation Complete!

NOTE: NOZZLE REPLACEMENT PROCEDURE

The FlowTech nozzles can be swapped while the hotend is at room temperature.

Pull the silicone sock off of the heater core.
