Model [X] AON-M2 [X] AON-M2 2020
Category [X] Preventive [ ] Corrective [ ] Troubleshooting

Summary

The procedure that follows explains how to inspect the Y-axis idlers.

Y-axis idlers in good condition prevent:

  • Rough belt operation that cause belt damage.
  • Inconsistent print layers.
  • Unwanted loud noises and vibrations during movement.

Tools

None required.

Parts Information

None required.

If the machine is presently equipped with the older version of the Y-idlers, AON3D recommends upgrading to the Y-Idler Field Upgrade Kit (K-0302-003). This kit includes two Y-idler assemblies that will greatly improve the print quality and overall machine reliability. The Y-Idler Field Upgrade Kit (K-0302-003) is offered to all AON-M2 and AON-M2 2020 owners at no additional cost as a one-time upgrade when upgrading from the original Y-idler assembly only. Please reach out to our Customer Success team at help@aon3d.com with your company name and machine serial number (identification plate is found at the back of the machine).
