Inspect Coolant Level

Model [] AON-M2 [] AON-M2 2020 [] AON M2+ [] AON M2+ (CE)
Category [] Preventive [ ] Corrective

Summary

The procedures that follows gives instructions on how to inspect the coolant level in the coolant reservoir.

The correct coolant levels prevents:

  • Machine components that operate too hot.
  • Machine component failures.
  • Unsatisfactory print quality.

Estimated time: 15 minutes

The coolant pump configurations are different between the AON M2+/AON-M2 2020 and the original AON-M2 model. Instructions for both configurations are found on this page:

Prepare the Coolant Bottle

Koolance bottle and tube

  1. Remove the coolant bottle cap to assemble the rubber spout onto the coolant bottle.
  2. Remove the rubber spout and set aside.
  3. Remove the plastic center cap. Do not discard the center cap as it can be reused to reseal the coolant bottle.
  4. Put the rubber spout upright on the coolant bottle opening.
  5. Secure the rubber spout assembly onto the coolant bottle with the cap.
  6. Install the clear filler tube onto the rubber spout (AON-M2 application only).

The installation of the clear filler tube is for the AON-M2 application only.

Prepare the Machine

  1. Push the E-stop button.

AON M2+ and AON-M2 2020 Coolant Level Fill

Only use the AON3D recommended coolant. Failure to use the recommended coolant can cause damage to the machine component(s) and cooling circuit.

  1. Make sure that the coolant level in the coolant reservoir (1) is approximately 2.5 cm (one inch) from the top. 2.5 cm
  2. If there is not sufficient coolant in the coolant reservoir (1), do steps 3 to 7.
  3. Use the large flathead screwdriver to remove the coolant reservoir cap (2). Coolant Reservoir Cap
  4. Put the tip of the small funnel into the coolant reservoir (1).
  5. Carefully add coolant in the coolant reservoir (1) until the coolant level is approximately 2.5 cm (one inch) from the top.
    • If coolant overflows, clean with lint-free rag(s).
  6. Install coolant reservoir cap (2) onto the coolant reservoir (1).
  7. Use the large flathead screwdriver to tighten the coolant reservoir cap (2). Do not tighten too much.

AON-M2 Coolant Level Fill

Only use the AON3D recommended coolant. Failure to use the recommended coolant can cause damage to the machine component(s) and cooling circuit.

AON3D now uses a different coolant solution from the one originally shipped with the AON-M2 machine. AON3D recommends to change the coolants when the recommended annual coolant flush is performed. A thorough coolant flush is necessary when a change in coolant types is done. Refer to Drain and Fill Coolant.

  1. Make sure that the coolant level in the coolant reservoir (1) is approximately 2.5 cm (one inch) from the top. Full Reservoir
  2. If there is not sufficient coolant in the coolant reservoir (1), do steps 3 to 6.
  3. Use the large flathead screwdriver to remove coolant reservoir plug (2). Show pouring coolant
  4. Carefully add coolant in the coolant reservoir (1) until approximately 2.5 cm (one inch) from the top.
    • If coolant overflows, clean with lint-free rag(s).
  5. Install the coolant reservoir plug (2) into the coolant reservoir (1).
  6. Use the large flathead screwdriver to tighten the coolant reservoir plug (2). Do not tighten too much.

Test and Return to Service

  1. Release the E-stop button.
  2. Home XYZ.
  3. Make sure that coolant does not leak on the outside of the machine while the cooling system is in operation.
