[Help with lithophane]

I have done all that.  I just used bed to take picture.  But I appreciate your response, thank you.  It bothers me because everything else i print comes out really good, except lithophanes

[Help with lithophane]

So recently I have upgraded to direct drive on my Ender 3 v2.   I have been printing lithophane before the upgrade with pretty good results.  Now that I've switched to DD i haven't had any luck with it.  I have done many calibrations and i am still having problems.   Maybe someone out there can help guide me or let me know what the issue can be.  I have included the old unit print and DD unit print as you can see the difference in quality.
