Not really. I’m generally working in a relatively narrow range of materials when I’m doing this - 3mm to 3/8". The 0,0 point I’ve created is always going to be the same - the camera’s perception of material aligned with it is what is affected by the material thickness.
So my 20x12" artboard defines (effectively speaking) the 0,0 offset for my actual project. If I’m an inch up & over from the lower left corner in Corel, then the GFUI has it an inch up & over as well and every design I do will show up there as well.
The trick is getting the camera view to align close enough to drop it at the inch up & over point on the material. That’s where everyone’s challenges are coming from. GF says that we can expect what I’d now call the 1,1 location on the artboard might be .75-1.25 in either up or across position - a quarter inch off but it could be a quarter left or right so actually up to 1/2". (I’m assuming the 1/4" stated potential margin of error is + or - but it could be they mean it is really + - 1/8"…I set my expectations conservatively and have been pleasantly surprised as I achieve better accuracy ️ ).
So when I want precision I place a targeting reticle at the upper or lower left corner of the artboard. Then I set the GFUI to 200% magnification (after setting the material height if needed) and move the drawing so the reticle lines up with the 0,0 on the GFUI’s ruler (for an upper left reticle). I’m always pretty close - one or two clicks and that’s entirely based on whether I drop the blue artwork bounding box (Ctrl-A in the GFUI) exactly on top of the ruler line or if there’s a hair of ruler showing.
Of course once it cuts the resulting red (magenta?) lines are not precisely aligned with the cut image on the physical material. That’s when you trust your instruments and not your seat of the pants sensibilities of what it “should” be because your eyes (camera) are fooling you.
