X and Y Axes Perpendicularity Inspection

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

Summary

This procedure gives the instructions on how to do an adjustment of the X and Y axes. Perpendicular axes prevent:

  • X-axis and/or Y-axis binding.
  • Loud noises when the axes move.
  • Layers not equal.

Tools

Qty Description Specification
1 Machinist Block N/A
1 Cloth Lint-free
1 Hex key 2.5 mm
1 Hex key 4 mm

Personal Protective Equipment

Qty Description Specification
1 Safety Glasses N/A

Prepare the Machine

  1. Home XYZ.
  2. Lower the Z-axis by 200 mm.
  3. Push the E-stop button.
  4. Wait until the build chamber, build plate and hot ends are at room temperature.

Inspect X-Y Axes Perpendicularity

  1. Put the machinist block (1) so that the sides are in contact with the Y-axis rail (2) and the mounting plate under the X-axis assembly (5). Machinist Block References
  2. Make sure that there is no space between the machinist tool and the components.
  3. Do the steps 1 and 2 again on the other side.
  4. If you see a space between the tool and the components, adjust the perpendicularity of the axes.

Adjust XY Axes Perpendicularity

  1. Remove the X-axis assembly from the mounting plates:
    1. On the left side of the machine, loosen the four screws (4) from under the X-axis assembly (5). Left Screws Removal
    2. On the right side of the machine, loosen the four screws (6) from under the X-axis assembly (5). Right Screws Removal
    3. Carefully remove the X-axis assembly and place it on the build table.

      The X-axis assembly has multiple wires and tubes attached to it. Do not twist or pull the assembly too much. Failure to do so may result in damage to the components of the machine.

  2. Adjust the mounting plates:
    1. With the 2.5 mm hex key, loosen the four screws (7) that hold the mounting plate (3) in position. Adujstment Screws for Mounting Plate
    2. Place the machinist block (1) so that the sides are in contact with the Y-axis rail (2) and the mounting plate (3). Hold the machinist block in this position. Machinist Block References
    3. Push the mounting plate (3) against the machinist block (1).
    4. Tighten the four screws (7) by hand, in a criss-cross manner, to lock the mounting plate in position.
    5. Put the machinist block (1) in the same position as step 2.b. and make sure there are no gaps between the machinist block and the components (2) and (3).
    6. Repeat steps 2.a. to 2.e. on the other side of the machine.
  3. Clean the contact points of the X-axis assembly:
    1. With a cloth, clean the two holding plates (3).
    2. Clean the underside of the X-axis assembly fixation points (7).
  4. Install the X-axis assembly:
    1. Carefully put the Y-axis assembly back in position on the two plates.
    2. Install the four screws (4) not fully in the left-side holding plate. Left Screws Install
    3. Install the four screws (5) not fully in the right-side holding plate.

      Do not over-tighten the screws. This can cause damage to the machine, and fasteners. Only tighten the screws until they are not loose.

    4. With the 4 mm hex key, tighten the screws (4) and (5) by hand, in a criss-cross pattern.

Return to Service

  1. Release the E-stop button.
  2. Home XYZ.
  3. Lower the Z-axis by 200 mm.
  4. For T0, move the X and Y axes approximately 300 mm.
  5. Home XYZ.
  6. Make sure there is not more noise or vibration than usual.
  7. Do the steps 3 to 6 two times more.
  8. Do the steps 3 to 7 with T1.
