Bambu Suite cutting plotter

Hey, I can’t seem to get my knife cutting plotter to work. I’ve printed some stickers, for example. I place them on the table. I upload a DXF file containing the cutting paths to Suite. I take a picture of the table with the camera. I can’t seem to get the cuts right. There’s always some offset. I suspect the camera is taking the picture at an angle. I’ve adjusted the graphics and then the cutting paths to the registration marks, but the cutting path is still offset. Can anyone help me solve this problem?
