i dont know what the problem is and how to fix. please help. im using CR-10s Pro.

Hi mykyubi9, welcome to the forum. Could you post a top down image of the model in Cura?

like this?

My suspicion is that it is the model. If the thin, diamond cross-sectioned segments are stacked in the original model, make sure the vertices are fused. In addition, you can use smoothing to hide the triangles in your print.

Maybe rotateing the model would help.
Is it online available ?
