So, I was perusing this old thread - https://www.practicalmachinist.com/...tips-tricks-294512/index2.html?highlight=tips
And came across the below process to vertically align the wire after changing guides.
I have used it a few times and it works damn good, but I have been using the rule of thumb adjustment in the below quote.
My trignometry is pretty bad, does anyone know the actual formula to figure the adjustments out? Assume a Z change of +8.0.

Another method for squaring up a head. We essentially stole the Charmilles method of the auto squaring procedure, but just do it manually. We made a block, (any of you with Charmilles, at least older ones, will probably recognize it) .75" wide by 3" long, with a little "loop" made out of some carbide, about 1/16" thick, screwed onto the end of it. You simply pick up the center of this loop with the wire at, say, Z 1", then bring the head up 6 or 8 inches and pick it up again. If the wire is vertical the pickup will repeat, if it's off the angle changes and you get a different center. If it's off, you can either just trig out how much to shift the U and V, or just do what we do, shift the U or V double the amount the X or Y is showing to be off, it's generally close enough to get it on one shot as long as the head isn't out a mile. We've adopted this method on all our machines, Sodick, Fanuc, Charmilles, Mits, Chmer, and it works great on all of them.
The block is about 3/4" thick. It really doesn't matter much though, the important part is getting a good Z distance between the two pickups to establish your trig triangle, if that makes any sense. Attached a picture of said tool.
