All that time lost, you would probably be happier with a solid jig technique. There are lots of methods, the easiest is probably to put tape on the bed, score circles where you want your coasters to go, then carefully align them on it, ignore the camera and go.
I also like corner jigs for coasters.
It’s an extra step, but it’s bulletproof and is definitely faster than wasting time and energy.
Since this problem is being seen on materials that were purchased from another company, we can’t offer support for prints that don’t come out as expected. Materials may vary widely from piece to piece, even if they’re created by the same manufacturer. I’m going to move it to Beyond the Manual so other folks here can help. Should this happen with a print on Proofgrade materials, please open a new ticket in Problems and Support and we’ll help you right away!
