With planning you can minimize waste.
Right now the width of the accessible material to process is bigger than what goes in the workspace. So the wide ends of the ProofGrade may get used last. I have used up the centers on some pieces to be able to cut the material in half and then used the ends, which aren’t too big, but make up a lot of material overall. I have found that in the six weeks I have had a Glowforge that the accessible bed has gotten a bit bigger for this pre-release unit. Either that or I am getting better at noticing these things.
The camera positioning allows for pretty precise placement to use up material efficiently. I can always find uses. It may take a while but I could just keep accumulating Scrabble tiles as I use up the odds and ends. On the other hand you can also design to use the whole workspace in one print.
In the following image, I cut it a bit too close at the top. I’m using a utility knife to score and cut bigger sheets. The side got a little splintery. I could have left a little bit more room for positioning. It would have fit but I needed to pay more attention to how square the material was. That’s where a jig or hard stops might be handy. Otherwise you just give a 1/4 inch leeway around the perimeter and you can do the whole piece and allow for fuzzy placement enough.
Layout in workspace before printing:
Results. It actually is a complete cut on the underside of the material. Here are the edges of that would have been at the top edge of the cut. The one bottom one in the picture displays the char of a complete cut through the thickness of the wood except for a slight triangle on the left side. The upper one in the picture displays char through about 1/2 of the thickness of the wood across the whole edge. Would have made it fine if I had put the material in a little straighter.
