Summary

The procedure that follows gives instructions on how to install the Filament Dry Storage and Feed System (dry box) assembly onto the AON3D machine.

Estimated time: 60-90 minutes

Two Filament Dry Storage and Feed Systems (dry boxes) can be installed on the AON-M2 machines.

The advantages of a Filament Dry Storage and Feed System (dry box) is as follows:
• Helps keep the filament clean.
• Helps keep the filament in a dry enclosure.
• Helps control the level of humidity in the filament (with the use of desiccant pouches).
For more information on the importance of filament moisture control, refer to Filament Drying and Moisture Control.

  3. Do steps 1 and 2 for the adjacent side, if necessary.

Install the Machine and Dry Box Brackets

Install the Machine Bracket

Install Machine Bracket

  1. Install the machine hanger bracket (1) onto the rear machine panel as follows:
    1. Align the machine hanger bracket (1) holes to the two top holes that were used to hold the two spool holder brackets. Make sure that the bend of machine hanger bracket (1) points UP.
    2. Manually install the two screws (2) through the machine hanger bracket (1) and into the two top holes of rear panel of the machine.
  2. Use the 3 mm hex key to tighten the two screws (2). Make sure that the two screws (2) are tight.
  3. Do steps 1 and 2 for the adjacent machine hanger bracket (1), if necessary.

Install the Dry Box Enclosure Assemblies

Install Dry Box T0/T1

  1. Carefully install the dry box enclosure assembly onto the machine hanger bracket.
  2. Make sure that the dry box hanger bracket tab (1) and the notch on machine hanger bracket notch (2) engage correctly.
  3. Do steps 1 and 2 to install a dry box enclosure assembly for the adjacent toolhead, if necessary.

Dry Boxes Installed T0/T1

Prepare the Dry Box Enclosure Assembly

Prepare the Dry Box Enclosure for T0 Operation

When the machine is viewed from the rear, the dry box enclosure on the LEFT must feed the RIGHT toolhead (T0). Failure to do so can cause print failures and/or damage to machine component(s).

Prepare Dry Box for T0

  1. When the machine is viewed from the rear, do the steps that follow for the LEFT dry box assembly:
    1. Remove the plug (1) that is installed in the top LEFT dry box feed tube fitting (2).
    2. Open the lid to the LEFT dry box enclosure.
    3. Push the new 152 mm (6 in) feed tube (3) in the bottom of the LEFT dry box feed tube fitting (2). Lightly pull on the 152 mm (6 in) internal feed tube (3) to make sure it is correctly installed in the dry box feed tube fitting (2).

Prepare the Dry Box Enclosure for T1 Operation

When the machine is viewed from the rear, the dry box enclosure on the RIGHT must feed the LEFT toolhead (T1). Failure to do so can cause print failures and/or damage to machine component(s).

Prepare Dry Box for T1

  1. When the machine is viewed from the rear, do the steps that follow for the RIGHT dry box assembly:
    1. Remove the plug (1) that is installed in the top RIGHT dry box feed tube fitting (2).
    2. Open the lid to the RIGHT dry box enclosure.
    3. Push the new 152 mm (6 in) feed tube (3) in the bottom of the RIGHT dry box feed tube fitting (2). Lightly pull on the 152 mm (6 in) internal feed tube (3) to make sure it is correctly installed in the dry box feed tube fitting (2).

Install the Roll of Filament

Dry Boxes Installed Preview

Filament spool limit dimensions are as follows:
• Largest outside diameter: 305 mm (12 in)
• Smallest inside diameter: 32 mm (1.25 in)
• Largest width: 110 mm (4.33 in).

Install the Roll of Filament for T0 Operation

  1. When the machine is viewed from the rear, do the steps that follow:
    1. Use the 4 mm hex key to loosen the spindle collar screw (1). Remove the spindle collar (2). Spindle Collar T0

      When the machine is viewed from the rear, the roll of filament must be installed as such that the filament unwinds CLOCKWISE into the internal 152 mm (6 in) feed tube. Failure to install the filament correctly into the feed tube can cause print failures and/or cause damage to machine component(s).

      Make sure that filament is unrolled from the spool without tangles. Filament tangles will cause print failures and/or cause damage to machine component(s).

      Install Roll Filament T0
    2. Install the roll of filament onto the filament spindle (3). Push the roll of filament to the rear of the dry box. Make sure that the roll of filament is correctly installed.
    3. Install the the spindle collar (2) onto the filament spindle (3). Put the spindle collar (2) approximately 7 mm (one-quarter inch) away from the roll of filament.
    4. Use the 4 mm hex key to tighten the collar screw (1). Do not tighten too much.
  2. When the machine is viewed from the rear, install the 762 mm (30 in) feed tube as follows:
    1. Push the 762 mm (30 in) feed tube (4) into the top of the LEFT dry box feed tube fitting (5). Lightly pull on the 762 mm (30 in) feed tube (4) to make sure it is correctly installed in the dry box feed tube fitting (5).
    2. Push the other end of the 762 mm (30 in) feed tube into the RIGHT (T0) filament sensor fitting (6). Lightly pull on the 762 mm (30 in) feed tube to make sure it is correctly installed in the filament sensor fitting (6).

      Please reach out to our Customer Success team at help@aon3d.com about SB-2020-03 if the filament sensor fitting does not have the correct feed tube diameter.

  3. Use the wire cutter to cut a 45-degree angle at the end of the filament. Cut Filament for Entry
  4. Put the end of the filament into the 152 mm (6 in) internal feed tube.
  5. Carefully push the filament through the feed path until it exits the feed tube found inside the build chamber.

    AON3D recommends that two small desiccant pouches be installed in the dry box enclosure to prevent moisture.

  6. Make sure that you remove the tools from the dry box enclosure.
  7. Close the lid to the LEFT dry box enclosure.
  8. Load the filament into the extruder. Refer to Load Filament.

  1. When the machine is viewed from the rear, do the steps that follow:
    1. Use the 4 mm hex key to loosen the spindle collar screw (1). Remove the spindle collar (2). Spindle Collar T1

      When the machine is viewed from the rear, the roll of filament must be installed as such that the filament unwinds COUNTERCLOCKWISE into the internal 152 mm (6 in) feed tube. Failure to install the filament correctly into the feed tube can cause print failures and/or cause damage to machine component(s).

      Make sure that filament is unrolled from the spool without tangles. Filament tangles will cause print failures and/or cause damage to machine component(s).
