First print issues (noob)

I would recommend leveling your print plate then re-slicing the files in Chitubox rotated 45 degrees on the X and Y axis then add supports. You can download the rook file here: https://www.thingiverse.com/thing:3962430
Rotating 45 degrees on the X and Y axis is a thing I always do and it greatly improves print quality.
