shrink/warp printing multiple parts simultaneously

[airscapes]

So.. what does the part look like.. does it have pointy corners? If so try and add a fillet to round the corner if you designed the part. What PLA are you using.. if it is the stuff MakerGrear gave you with the printer and it is black, toss it in the trash and buy some eSun pla+. If you are using .1mm layer height, try .3 and see if things improve..
I don't use much PLA any more, I prefer PETG or ABS with a home made enclosure for my MakerGear M2. I printed a part in eSun PLA what was designed by a family member which had sharp corners and they warped as I expected as I used .1mm layer to makes some angled areas look less stepped..
