The printed circular structure is measured with calipers, and it is found that the circumferential roundness deviates too much.

1. The belt in the X or Y direction is loose in the running component.

2. The screws of the pulley and synchronous pulley are loose.

3.XY components are not parallel

Print the circular model and mark it as shown in the image above. (the above image is the top face of the print model, the red line “3” white part is directly in front of the printer, and the black part is directly behind the printer).

Measuring the diameter of a circle with a Vernier caliper

1. When the red line “1” direction diameter is minimum, the sliding sprinkler assembly checks whether the X direction is smooth, if smooth, the X belt can be tightened.

2. When the diameter of the red line “3” is the smallest, the sliding sprinkler assembly checks whether the Y direction is smooth and the Y direction belt is too loose, and tighten the Y motor belt if normal.

3. When the diameter of the red line in the “2” direction is the smallest and the diameter in the “4” direction is the largest, it may be that the Y direction is not horizontal, then you need to loosen the two screws in the position shown by the arrow in the following picture, and manually adjust the two aluminum profiles in the red circle to move slightly to the right, and then tighten the two screws. This is shown in the following figure.

4. When the diameter of the red line “4” is the smallest, and the diameter of the “2” direction is the largest, it may be that the Y direction is not horizontal, so it is necessary to loosen the two screws at the position shown by the arrow in the following picture, and manually adjust the two aluminum profiles in the red circle to move slightly to the left. Tighten two more screws. This is shown in the following figure.
