Prepare the Machine
Make sure that there are no prints on the build surface. Remove print(s) before the procedure that follows is started. Failure to do so can cause a collision and cause damage to the machine component(s).
- Home XYZ.
- Lower the Z-axis by 300 mm.
- Open the build chamber door.
- Push the E-stop button.
- Turn the power OFF with the ON/OFF switch found behind the machine.
-
- For AON M2+ (CE) machines: Disconnect power to the machine from the local supply disconnecting device.
- For AON M2+ (R-NZ), AON M2+, AON-M2 2020 and AON-M2 machines:
Disconnect the main power cord from the receptacle.
Dangerous voltages continue to be found in the electrical panel when the ON/OFF switch is set to OFF. Disconnect the main power cord from the machine while maintenance is done. Failure to do so can cause electric shock.
- Wait until the build chamber, build platform and hot ends are at room temperature.
Remove the Z-Axis Belts
Wait until all the machine components are at room temperature before you continue. Some machine components can be hot if the machine was recently used. Failure to do so can cause injuries.
- Use the 4 mm hex key and 8 mm wrench to loosen the four screws (1). Do not remove the four screws (1).
- Use the 8 mm wrench to loosen the jam nut (2).
- Loosen the Z-axis tension nut (3) until there is no tension on the Z-axis belt.
- Remove the Z-axis belt from the machine.
- Discard the Z-axis belt.
- Make sure the Z-axis motor pulley(s) and the lead screw pulley(s) are clean and free from unwanted material and/or contaminants. Use a lint-free rag and isopropyl alcohol to clean, if necessary.
- Do steps 1 to 6 for the components on the adjacent side, if necessary.
Install the New Z-Axis Belts
Make sure that the belt teeth engage correctly with the teeth of the Z-axis motor pulley and the lead screw pulley. Make sure that the belt is installed straight, with no twists, no kinks, and/or no loops. Failure to do so will cause irregular print quality and/or will cause damage to the machine component(s).
- Put a new Z-axis belt in position around the two Z-axis motor pulleys and the lead screw pulleys.
- Adjust the Z-axis belt tension. Refer to Inspect and Adjust XYZ-Axes Belt Tension.
- Do steps 1 and 2 for the components on the adjacent side, if necessary.
Test and Return to Service
- Make sure that you remove all the tools from the build chamber.
- Close the build chamber door.
-
- For AON M2+ (CE) machines: Connect power to the machine from the local supply disconnecting device.
- For AON M2+ (R-NZ), AON M2+, AON-M2 2020 and AON-M2 machines: Connect the main power cord to the receptacle.
- Turn the power ON with the ON/OFF switch found on the rear panel of the machine.
- Release the E-stop button.
- Home XYZ.
