Big thanks to @trashpanda for finding this tool that can convert an STL into a depth map (either SVG or PNG): https://kbralten.github.io/STL_PNG_Depth/index.html

The black acrylic worked the best I think. Will be fun to test more deep engraving when I get some more (which should be tomorrow). Also need to figure out how to stop discolouration on the wood, especially on the deeper one.

Most likely a support visit from this type of company runs 500-100€ before work even starts. I've seen this even with a running service contract in the 1000s / month.

Chokepoint capitalism, baby.

But not as much as the StrataSys J-35 resin 3D printer we also have but never use because it's also wildly expensive to run 😝 so if anyone wants to buy a slightly used industrial-grade 3D printer...

That is absolutely a huge ammount of money.

Something that expensive should come with a support contract.

Aren't those like, really expensive?

Meanwhile, I can't get our Epilog laser at work to run at all right now... 😬😝
