Hey Chadd: would you be able to post A/B photos that illustrate the difference w/ heated vs not heated? It would be cool if for no other reason that it's kinda rare to see "smoking gun" diagnostic photos related to 3d printing!

The banding with the heat bed on is horrible so I know that the heat bed is causing the majority of the issues.

I am just going to go down my list of things and try to get it taken care of, too many people are having banding issues with the 12" printers so there has to be some inherent issue with the design/components used in them. I think we will find it is a combination of things that are stacking up and causing the problems.
