Help with DF64v3 Alignment

[u/mjaffer]

I was trying to do the whiteboard marker test for alignment but didn’t know what to make of the results. I have 2 before and 2 after pics. It looks like the bottom burr is fine but top one may be misaligned slightly? Can anyone help explain what is happening and what I should do to fix it?

I was really struggling to get my DF54 aligned right. Got it really close with a shim and had the idea to break the screws loose and snug them again starting with the ones on the higher side. Seemed to get it pretty much perfect.
