Blaze72: i've been having trouble figuring it out by reading various other guides and it confusing me
For me the H27 - Blueprints
I31 - Will
is it N24 when i fixed the calibration......or am i not even close?
It's a co-ordinate grid of letter x number. There's an origin point that starts on M20. So, you want to recalibrate it so that it has a new origin point that's the difference between the co-ordinates of the will and the blueprint.
Will is on I31. The difference from that to the blueprint (H27) is -1 letter and -4 number. Apply that to the origin point. Spoiler: L16.
