How to output Print String into a UI Widget?

Cool, thanks! v1 and v2 are in fact my Loc1 and Loc2 variables, correct?

Seems like it works, but there’s a deviation. What should return as delta X = 3m is actually being printed as 5.196m. In the editor, block A is at X120 Y-200 Z200 and block B is at X420 Y-60 Z200, so difference of X is 300.

The “Delta X: 300” is just a static text render so I don’t forget what delta X should be.
Here’s my blueprint:

Which leads to the widgets and prints for each individual delta:

So every Delta print has a deviation by the way, factor ~1.7 for what it’s worth… what gives?
