Does anyone know the formula for Triffid Hunters Alignment and Calibration Cube?

I've spent the day trying to open it using Parallels/Windows10 and it still states "still loading"
As you may have guessed, I don't have any Microsoft devices.

@Dizzwold one for @mrehorstdmd !

@Dizzwold what formula are you referring to?
-
What I'm referring to is what are the calculations done, from inputting the measurements from the printed cube, to getting the results to set the X, Y and Z?
As I can't open it, I can't tell
Is it the same as when calculating and setting Esteps/per mm, except your doing it on the X, Y and Z ? -
@Dizzwold No, it uses the diagonal measures of the cube in each plane to calculate the mechanical displacement of the ends of the guide rails required to put the axes into a square relationship.
The spreadsheet opens in LibreOffice Calc.
error angle in degrees: =DEGREES(ASIN((B16^2-B13^2-B14^2)/(2B13B14)))
B13 is the X dimension of the square, B14 is the measured Y dimension of the square, and B16 is the length of the longest diagonal. (if the diagonals are equal, the axes in question are square).
Error angle in mm/m is : =B20/3602000PI() where B20 is the error angle in degrees
Error in the end of the X axis guide rail position: =B22B10/1000 where B22 is the error angle in mm/m and B10 is the X length of the square.
Error in the end of the Y axis guide rail position is : =B22B11/1000 where B11 is the Y length of the square. -
Thank you for quoting LibreOffice, I've got it up and running now (on my Mac).
