My first layer seems to be off

[AlmondPA 1]

I have a UM2 and am printing with Matterhackers 3mm PLA. My first layer seems to be consistently off. I have tried to re-calibrate the print bed and there is a little effect but not a big difference. My concern is that I seem to get 'pillowing' or what I assume to be some sort of pillowing at the top but seems to be pervasive throught the layers of the print.

Being new to 3D printing, I am happy to post whatever information would be helpful in sorting this out. Thanks in advance for helping, I do appreciate it.

Does quality of the PLA make a difference. I just loaded some ColorFabb and the print looks solid. Think this might be coincidence or PLA quality does make a difference?

Your bed isn't perfectly calibrated. Try to check https://ultimaker.com/en/resources/18769-calibration

It looks like your bed is a little bit too low.

Mostly noticeable in surface finish, white PLA is not the most forgiving material to print with. The added pigment to make it white can influence its behavior.

Neotko and SandervG thank you for your help. This morning I re-calibrated and the prints are much better. I really appreciate the help
