Inspect Linear Components and Lead Screws for Contamination

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

Summary

The procedure that follows gives instructions on how to look for contamination and unwanted material on the linear rails, linear shafts and lead screws.

Clean components prevent:

  • X, Y, and/or Z-axes binding.
  • Loud noises when the axes are in motion.
  • Unsatisfactory print layers.

Estimated time: 15 minutes

Tools

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).

  1. Home XYZ.
  2. Lower the Z-axis by 300 mm.
  3. Push the E-stop button.
  4. Open the build chamber door.
  5. Wait until the build chamber, build platform and hot ends are at room temperature.

Inspect the X-Axis Linear Rail

Allow all machine components to reach room temperature prior to proceeding further. Failure to allow components to cool down will result in thermal injury (burns) to personnel.

X-Axis Inspection

  1. Manually move T0 (2) to the center of the the X-axis linear rail (1).
  2. Inspect the X-axis linear rail (1) surfaces for contaminants.
  3. Manually move T0 (2) to the left-hand side of the X-axis linear rail (1). Inspect X-axis linear rail (1) for contaminants.
  4. Manually move T1 to the center of the the X-axis linear rail (1).
  5. Inspect the X-axis linear rail (1) surfaces for contaminants.
  6. Manually move T1 to the right-hand side of the X-axis linear rail (1). Inspect X-axis linear rail (1) for contaminants.
  7. Remove all contaminates as necessary. Refer to Clean and Lubricate X/Y-Axes.

Inspect the Y-Axis Linear Rails

Y-Axis Inspection

  1. Manually move the Y-axis gantry (4) to the rear of the build platform.
  2. Inspect the two Y-axis linear rail (3) surfaces for contaminants. Look for signs of contaminants such as liquids and/or dust.
  3. Manually pull the center of the X-axis gantry (4) to the center of the Y-axis.
  4. Remove all contaminates as necessary. Refer to Clean and Lubricate X/Y-Axes.

Inspect the Z-Axis Linear Shafts and Lead Screws

Z-Axis Inspection

  1. Inspect the Z-axis linear shafts (5) and both lead screws (6) for contaminants.
  2. Close the build chamber door.
  3. Release the E-stop button.
  4. Home XYZ.
  5. Lower the Z-axis bed assembly to the bottom of the build chamber.
  6. Raise the Z-axis by 150 mm.
  7. Push the E-stop button.
  8. Open the build chamber door.
  9. Look for signs of contaminants.
  10. Remove all contaminants as necessary:

Test and Return to Service

  1. Close the build chamber door.
  2. Release the E-stop button.
  3. Home XYZ.
