Linear Components and Lead Screws Inspection for Contamination

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

Summary

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

Clean components prevent:

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

Estimated time: 30 minutes

Prepare the Machine

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

Inspect the X-Axis Linear Rail

X-Axis Inspection

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.

  1. Manually move T0 (2) and T1 to the center of the the X-axis linear rail (1).
  2. Inspect the X-axis linear rail (1) surfaces for contaminants. Look for signs of contaminants such as liquids and/or dust.
  3. Manually move T0 (2) to the left-hand side of the machine along the X-axis linear rail (1). Inspect X-axis linear rail (1) for contaminants.
  4. Manually move T1 to the right-hand side of the machine along the X-axis linear rail (1). Inspect X-axis linear rail (1) for contaminants.
  5. Remove all contaminates as necessary. Refer to Clean and lubricate the XY-axes.

Inspect the Y-Axis Linear Rails

Y-Axis Inspection

  1. Manually move the Y-axis gantry (4) to the back of the machine.
  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 push the middle of the Y-axis gantry (4) to the center of the Y-axis.
  4. Remove all contaminants as necessary. Refer to Clean and Lubricate XY-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. Release the E-stop button.
  3. Home XYZ.
  4. Lower the Z-axis bed assembly to the bottom of the build chamber.
  5. Push the E-stop button.
  6. Look for signs of contaminants such as liquids or dust.
  7. Remove all contaminants as necessary. Refer to Clean and lubricate the Z-axis.
  8. Close the build chamber door.

Test and Return to Service

  1. Release the E-stop button.
  2. Home XYZ.
