Delta value calculation

Recommended Posts

The Delta Value is a measurement of how much the Coordinate System has shifted from one measurement of the Base Alignment to the next.
Delta is the accumulation of the X,Y,Z,X-Y Rotation and X-Y Tilt.
The shift is the result of the data points being taken in slightly different locations each time the alignment is looped.
Exact formula, I have no idea 😕

Ok, I think it might be the length of the position vector from one coordinate system to the previous.

valueA=(rad((arctan(baseSystem().y/baseSystem().x)-baseSystem().rot.asDEG)).cos*(sqrt(squared(baseSystem().x)+squared(baseSystem().y))))+(rad((arctan(baseSystem().y/baseSystem().x)-baseSystem().rot.asDEG)).sin*(sqrt(squared(baseSystem().x)+squared(baseSystem().y))))+(baseSystem().z)+(((baseSystem().rot.sin+baseSystem().rot.cos)-1)*2)

Hello,

Thanks for the formula ! I was looking for this since long time.
Does anyone know why this formula was chosen ?
For example, in my plan, I often use the break condition "baseSystem().valueA<0.01" but I don't really know why I put 0.01...
