Anyone know whats going on here?

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.

Alignment of irregular objects (Coasters)

I got a set of slate coasters. Unfortunately slate’s a pretty analog material, and each square was very slightly different. Under normal circumstances, this would not be an issue, as the differences were very small… but these are to be a matched tiling set, and so alignment was crucial. The way I solved for it was to make a “consumable” jig. Carefully measure your coaster: length, width and height. Be sure to mark the bottom somehow so you know your orientation later. Go to your favorite S…

It’s an extra step, but it’s bulletproof and is definitely faster than wasting time and energy.

Also, all is not lost on those missed prints:

Settings for Engraving on Slate

I just found out that rescuing slate from a botched engrave is possible. I started something and realized I screwed up a setting, so thought maybe the coaster was ruined. 400 grit sandpaper and 3 minutes later, I was able to completely remove the screwed up portion, apply a tiny amount of mineral oil to darken the area and remove the stone dust, and start again. It looks perfect, actually.

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!
