Bed leveling issue

I got my X-Carve built last week and I’ve done a few carves. They looked good, but then recently I did a carve that went all the way to the waste board, and it looks I have a leveling issue, but it seems somewhat more severe than I’ve seen from others.

I did a bunch of searching but didn’t find much in the way of advice to address this (if I missed a post that answers the question, I apologize). Here is a photo to show what I’m seeing.

The amount of change over a relatively short portion of the x-axis seems higher than what I’ve seen elsewhere. Can anyone give me ideas of how to adjust? If it really is just a matter of surfacing the waste board, I’ll do that but I would like to adjust if possible first, to minimize the issue.
