So I’m finally getting ready to tackle making a Cajone Drum on the laser! Here is the one major problem, the dimensions of the Cajone are larger than the engraving bed, but smaller than the interior of the Basic (16.5 x 18 inches for the largest piece).
My question is, How would you tackle this? We can’t rely on the overhead camera because when we rotate the material within the laser, it needs to be close to laser kerf precision, up to 1/4" off is not going to work here. We’ll only be cutting the exterior edges of the cajone out of the material, so we’ll have the maximum bed size allowable.
My current idea is to load up each “side” of the Cajone into Inkscape, put it on a 20x12 storyboard, and precisely place the edge to be cut along the bottom of the storyboard 1 inch up from the bottom and 1 inch in from the left side. I’d then put a plus sign “+” on that bottom corner where the edge will be. I’ll then run the + first with the lightest score I can to make sure I’m all aligned, then ignore the Plus and run the cut.
Before I spend hours trying to work this out, does this at least make sense to all of you? Have you been able to accurately connect cuts that had to be done in two different jobs where the material HAS to be picked up and moved?
Here are the svg files for anyone interested in taking a look at them. This is a Cajone with a 30 degree slanted front. Should be a little easier for people with achy backs to play.

Thanks everyone! (Also, let me know if this topic should be moved, I wasn’t quite sure where to put it. But there are free laser designs that work when I make the Cajone in my woodshop, just not sure how to translate them into the laser)
