What specific information does the barcode have?
Thanks
The first 3 letters seem to relate to the type of Proofgrade. The last 3 are different for every piece.
Glowforge : barcode version number : random number
The random number is not totally random (I think certain materials have the same first character), but that will likely change to be fully random.
Interesting that you went with a random number instead of just pulling from a sequence. Iâm sure there is some marketing reason or something behind that. It doesnât seem like a random number would be too friendly for GF for managing settings, and wonât really distract others from copying as a starting point.
Donât mind me, this just tweaked my interest.
Itâs just an identifier that lets us look up the material information in a table in the cloud.
Yeah, I figured that since no other reason to barcode anything. It was the randomness of using a random number A database obviously wonât care.
I suppose the random number keeps your team from overanalyzing the numberingâ scheme for different flavors of PG though so that is a plus when surrounded by scientists and engineers.
Thanks
At least itâs not a GUID But it will be fun to see when/if their random number generator spits out a dupe.
Iâm totally unfamiliar with their backend engineering, but hereâs my terrible hot take:
You donât need to generate a PG code in order to use PG settings though - thereâs a drop-down that allows you to pick a PG material to tell the machine thatâs whatâs in there. Of course, that may or may not work with what youâre using if itâs not really PG and you donât get the value of their ability to tweak the settings to the actual lot or run of material that the PG QR code gives them - from lot to lot or different manufacturers the optimum settings for something like 1/8" maple ply could be different and their database can tell the rendering engine what to us in making the waveform whereas youâd only end up with an approximation based on something that works for a possibly very specific case.
Right. I wasnât listing this as a point of complaint, rather a note that itâs âone-wayâ in the fashion of a hash.
Yep. Part fo their secret sauce
But there probably isnât anything that would stop you from generating a code to use over and over without choosing in the UI? I doubt GF is keeping track of how many square inches of material are consumed up to the standard sheet size. I have no idea if a âclonedâ code would be handy or not and I can see where guessing codes can potentially be dangerous.
I was just kind of surprised they were doing random numbers. In my little engineering mind I would have blocked out numbers for testing and improving PG eg: 1XX series gets this, 2XX that, 3XX etc. and can see where their approach could have benefits over my initial thoughts. If itâs all machine generated and read then it really doesnât matter.
