Sorry or the glare on the photo - devilishly hard to take a pic of.
Issue is banding in the horizontal X axis It's not the marble, not the image (sometimes there is no banding at all on this particular image). Epilog quoted $1395 for an e-laser (their in house currently used brand sold with the new machines) retrofit to my coherent tube, or $2015 for the coherent.
Does it look like a laser issue or mechanical?
BTW, I ran the image in 2 directions to see if the banding stayed in the x axis - it did.
