Creating our own Proofgrade labels?

[dan]

@BSheremeto

Hopefully glowforge are going all the way with proof grade and giving each lot of a material they receive a unique qr code so that material setting can be specific to each lot to account foranufacturing variance (thickness on wood, ect)

Actually, each piece of material - not just each lot - has a unique identifier. When we assign the identifier to the material, we also record what kind of material it is.
