I've tried a couple tables, one glossy, the rest matte. The correciton step, once I do a quick scan, looks like a misformed star, and when I had four lasers operating, none of them were even similar. All were random with spikes and dips. I have no idea what I'm doi...see more »I'm having some calibration issues with this.
