I was thinking people are going to be trying to cut items without their crumb tray; and I know there’s lots of ways to calculate what height you need to bring an object within the laser target range but sometimes it’s finding something that is just the right height.
An adjustable crumb tray could be a neat thing to see. I’d buy one.
I’d be pretty happy with just a crumb tray that’s 0.5" shorter than the current one. Then you could use it for anything 0.5"–1.0" thick and the original crumb tray for anything under 0.5" thick.
Then to be fancy put a QR code on the plastic bits on the sides that the GF could use to recognize that you had it in there and automatically adjust the allowable material depth to be 0.5"–1.0" instead of 0.0"–0.5". It could automatically complain if it saw normal Proofgrade materials in there and tell you to switch trays. (Hmm. And maybe eventually we could have thick that would tell you to use the thinner crumb tray.)
User Secret_Sauce designed some 3D-printable risers for lasering thick materials without the crumb tray. They’re built at heights that make the math super easy (e.g., subtract 1" from material thickness to use the short riser).
I’ve used them a few times now, and they work great!
I like this concept. Something like shown below when flipped over to shallow side.
Would probably work for most items. Downside is slightly less square inches to work with when flipped to the Deep side.
NOTE: one inch and 1.5 are approximate to show concept only.
