Hardware Assembly

Begin by locating the extruders internals set in your 3MS kit.

Remove one extruder internal set from the bag.

Prepare the following for this step:

Stepper gear

Stepper gear screw

1.5mm Hex key

Using the 1.5mm hex key, screw the stepper gear screw into the stepper gear.

Ensure the screw is slightly sticking into the gear.

Attach the stepper gear to the stepper motor.

Prepare the following for this step:

Stepper gear (prepared previously)

Stepper motor

Slide the stepper gear onto the stepper motor shaft. Note the orientation of the motor. Ensure the stepper gear screw is on the same side as the flat-side of the stepper motor shaft.

Slide the edge of the gear to the edge of the stepper motor shaft.

Tighten the stepper gear firmly.

Prepare the following for the next steps:

Extruder

3x M3x30 SHCS (in extruders internals bag)

Filament Unit for 3HOME

NEMA17 Stepper motor (prepared previously)

2.5mm Hex key

Assemble the filament unit.

Place the 3x M3x30 SHCS through the extruder into the filament unit. Note the orientation.

Flip the filament unit over and place the NEMA17 stepper motor through the bottom. Note the orientation.

• Even though the picture doesn't show it, it is recommended to plug the stepper cable before placing the stepper into the 3HOME.

Flip the filament unit over again and tighten the three M3 bolts.

Prepare the following for this step:

Tension screw (in extruder internals bag)

Tension washer (in extruder internals bag)

Tension spring (in extruder internals bag)

Assemble the three as shown.

Install the tensioner into the extruder through the hole on the side.

Prepare the following for this step:

PC4-M10 fitting

Blue Collet clip

Locate the hole on the extruder and screw the PC4-M10 fitting into it.

Insert the short length of PTFE into the ECAS fitting on the opposite end of the extruder.
