The Mingda D3/Pro is an FDM 3D printer from Mingda with a 320 x 320 x 400 mm build volume.
Action: Start with the printer powered off. Check the frame for square, confirm both Z lead screws turn freely, inspect the dual Z rods for binding, and make sure the bed carriage travels smoothly across the full 320 × 320 mm plane without catching at the edges. Confirm that the direct-drive extruder, filament path, and toolhead wiring have no obvious rub points.
Symptoms: The first layer is perfect in one corner but too close or too far in another; mesh results differ depending on whether the machine reports a 9-point or denser mesh routine.
Likely cause: The supplied sources disagree on whether the leveling system uses 9 points or 36 points, suggesting firmware revisions or documentation drift rather than a single fixed behavior.
