Stage 04: Print Heads

Install the docking pins and ooze shield as shown.

PC4 - M6 Pneumatic Coupling

M3 x 12mm Bolt (2x)

M3x5x30mm Docking Pin (2x)

If you have the REVO Print Head upgrade, secure the pins to the upper holes.

Silicone Ooze Shield

M4 x 40mm FH (Flat Head)

Repeat for each print head being installed

Print Heads ship in the default SO3 config with brass CHT nozzles. If you purchased REVO upgrades, follow these next few steps titled "REVO" to convert them. If not, skip.

Remove plastic electronics cover.

Remove the SO3 Heater.

Secure REVO spacer

Attach REVO heater

Screw in REVO Nozzle

Fix REVO Electronics Cover.

M3 x 20mm (first)

M3 x 8mm

Lower the tool plate mounting bracket for the REVO position.

The default SO3 position has the bracket mounted using the lower holes.

Add lubricant to the inside of the tool plate.

Fix to the print head with three M3 x 8mm counter sunk screws.

Check that the docking bracket is secure and parallel to the extruder body.

Check that the docking lug is secure to the bracket.

Slide the print heads onto the docking pins.

Secure the cable guides to the Frame and Print Heads.

M3 x 4 FH (Flat head)

Connect the print head cable to the print head. Use two cable ties to hold in place.

Pull out the blue clip and then push the PTFE tube into the print head. Push the clip back to secure the tube.

Repeat for all print heads.

Secure the cable and filament tube to the spring steel cable guide using cable ties.

Position the first cable tie 10cm above the print head.

Space cable ties around 10cm apart.

Fix the final cable tie 5cm above the coupling.

Feed the print head cables and filament tubes into the electronics box.

Connect the print heads to the hub board.

The order is insignificant.

Feed the remaining filament tubing through the coupling, into the electronics box and through the corresponding coupling at the bottom of the box.

The tubing can be left long and fed directly into the dry-boxes for a more air tight path. Or can be cut leaving around an inch for easier feeding of filament. This part is up to you.
