Wrinkling/Waving/Rippling on large print bottom layer

[KaiborgStudios]

Currently working on a functional piece for a client, and the build plate face needs to be as smooth as possible. I seem to keep getting this effect on the first layer. Extrusion width is spot on, and vertical/horizontal beads just bairly touch on the first layer, so I'm assuming it's not an issue with extrusion or z-height? I'm stumped.

Thanks!

Changed the Global Z Offset to .02 and that did the trick! Thanks Jim!
