In all the years I’ve owned a Glowforge laser cutter, I’ve never needed to measure my Proofgrade… until now. Building a project with my Daughter, and knowing Proofgrade materials are 20" x 12" we planned something around that. But, it turns out, the material isn’t 20" x 12"! In fact, it seems to me, it’s not even measured in inches at all! As far as I can tell, it’s exactly 52cm x 30cm (20.47" x 11.81"). Now, the fact that I’m crazy isn’t in question here… but I don’t think I’m wrong. So is this the case? Are the sheets measured in cm? Am I the only one who didn’t know until now?
And then I have to wonder… Does the software actually think in cm natively? Would I be better off, in some way, creating my artwork in cm? I mean, when it comes to precision, and I want 1/8th of an inch, does the software actually calculate 0.3175cm? Or does it round off to 0.318cm? Or, worse, 0.32cm?
Yes… These are among the things that keep me up at night…
