Not answering for Dan, but since this is a forum where we all help each other and I’m the only one of two (and I might add the only one giving demonstrations, such as they are) I will chime in. Posted my latest video here. Edit: [Trying to be helpful and understanding for you @ihermit2] I am still trying to understand your need for a registration mark and many others’ needs for 0,0. I can understand that to get a top edge of the material truly parallel with the gantry, there needs to be a registration mark on the honeycomb.
You are probably so accustomed to a workflow using it that the way the Glowforge operates is a different beast. Not having a CNC router or other tool, but having spent the last two years reading and designing and gathering components, the base and the squareness of the bed is crucial. Using a camera to place where you want it is different.
The honeycomb cells have to be parallel. then the whole tray needs to be perfectly registered to the bottom of a Glowforge. All of which are pretty accurate, but that is beside the point. I have got to get uploaded the screen capture of the process of placing an item. I’ll post this and then get a YouTube up for it.
You either start with a catalog design or upload a custom file (top right of screen below title bar next to trace. Your design appears on superimposed on the image of the materials that are on the bed. Then you place the image where you want. You can resize it (proportionally only as I can recall) and you can rotated it as you wish. You can zoom in to a high level and line up your graphics lines where you want.
That’s what the end result that following video demonstrates. I hope I am helping further the discussion. Stay tuned for that screen capture of the process. I put it in it’s own topic.
