Depth problems

I am having issues with my x-carve carving my designs at different depths. Example in pics attached the “bottom” of the design is cutting at correct depth but the “top” is not cutting deep enough and at some points not even touching the material. At first I thought it was due to uneven material surface so I planed the wood on both sides to ensure level surface but still having the same issue!

Did you ‘surface’ your base material (waste board)?

It just started doing it. I haven’t had this problem with previous carves. Could ther be another issue?

Where did you set your z axis in relation to the problem area? You wasteboard could be the cause

Z axis was set at zero “bottom left”

And from the photo the bottom looks good and the top is off. Correct??

Correct

Do it in two carves or correct the wasteboard

Thanks I’ll try that
