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

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. Open the build chamber door.
  8. Push the E-stop button.
  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.
