Power changes when doing 3d Engrave on PG acrylic (banding)

Hello All, Wondering if anyone else has this issue, I did a 3D engrave on PG medium white acrylic and I got some banding that happened. I had seen this before but not as pronounced. I fixed this by scraping the bands down with a tool, however you can still see the banding. What is strange is it happened like 3 inches up into the print for about an inch and a half and then again near the end of the print in the text at the top. The text was all the same color (so the same depth). [20200129_0…
