Pixel Width of Noir

Hello Peopoly,

I would like to figure out the best angle for a surface print with this method:

But for that I need to know the pixel width of the phenom noir. On your website you say it’s 77um, in your setup guide it says 79 and matterhackers says it’s 72 um…

The exact pixel should be 76.5um…Can be calculated in the chitubox software
