Hello, I’ve searched but have not found a definitive answer to my question.
To perform the ‘official’ documentation for re-calibration there is mention to use proofgrade draftboard.
Proofgrade draftboard is not available but I am in need of re-calibrating.
What to do?
You can use any material that is cut to the 12 X 20 Glowforge size requirement. People have had success with cardboard, mdf, or other plywood.
I use cardboard. It MUST be perfectly flat, however.
You could get MDF cut down at the local hardware store if you don’t have anything else on-hand.
Thank you both… I wasn’t sure if it had to be a certain height to work…
I am guessing as long as it’s cut to the same size as the draftboard sold here… (12x20) it’ll be good.
