Hello, I need to do some CNC cuts on a 11x19 piece of 3/4" wood before I put it in the laser. I know that I’ll need to remove the crumb tray which I’ve done before using these tricks: Tutorial: How to cut without the Crumb Tray (Honeycomb) and I love the idea of doing the alignment setup per this: Perfect Alignment with the Glowforge from @john11.
But has anyone had success doing both, i.e. doing perfect alignment on a piece that has the crumb tray removed?
My only idea is to a.) take out the crumb tray and put in another board that is thinner per the first link, then b.) do the paper method from @john11 even though the focus will be way off (because the paper now will be way beyond the 0.4 or so max focus range and then c.) put my piece on the paper and thinner “crumb tray” piece. The only concern here is whether the laser on the paper will be so wildly off because it is outside the 0.4 or so focus max but maybe that doesn’t matter?
