The base of the printer wobbles.
Deformation of the base is caused by transportation.
To ensure it is level, the printer base is calibrated on a marble platform prior to leaving the factory. However, deformation is inevitable during transportation, and minor deformation does not affect the printer's operation.
To achieve the best print quality and user experience, it is recommended that the base is recalibrated to restore its levelness.
4.0 mm Allen key
10 mm-high column × 2
Loosen the two screws on the two sides of the base with a 4.0 mm Allen key.
Note: Do not remove the screws.

Put a 10 mm-high column under the non-overhanging foot pad.

If A and C foot pads are overhanging, put the columns under the B and D foot pads.
If B and D foot pads are overhanging, put the columns under the A and C foot pads.

If the A and C food pads arenon-overhanging, press the A and C positions.
If the B and D food pads arenon-overhanging, press the B and D positions.

If the base is stable, tighten the screws on the two sides of the base.
If the base is still unstable, repeat Step 2 and Step 3.
