Good news and bad news.
I have the knife, and a new box of the “best” blades. The Irwin, Bi-metal, spring steel.
I have the 2’ by 8’ by .035" thick magnetic sheet, but I tested my waste board with the dial indicator, and the front is .020" higher than the center, after surfacing.
My friend has the exact same reading on his machine.
After doing some searching I found it’s an issue for the XXL.
You can not have supports 40+ inches apart and not have bad flex (talking about the feet).
The leveling feet are purely wishful thinking, and should not even be included with the kit, so people don’t get confused and try to use them.
I don’t know, maybe a leveling foot in the center? When I first got it it was high in the center.
I’m going to take the feet off and set it on some dense foam board, and hope that will get it close enough.
Like @DanoInTx talks about in this post
Oh yeah! To end with good news. I found this awesome site to get my templates started!
I’m going to make pipe fitter templates 
Mmm Hmm!
