For easy print removal, get a pei sheet. For PLA, use the smooth side, and TPU/PETG on the textured side.

If you pick one up. And push your finger against the middel. It should not separate. Then it's good.

only one from the corner separates the rest are very strong

​

On the bottom side, you should see the bed structure, not the line structure. As you see in the pictures. So i guess the nossle. could be placed a little bit closer to the bed.

i cant really see anything besides the lines on the bottom but i do feel the rough texture of my build plate.

For a magnetic bed, you can also put the initial layer height 0.1mm higher than its base settings. It's more a bed is not 100% flat and straight and nossle hight callibration is not perfect bandaid. But it works.
