I have been trying to slice some lithophanes, which are quite high res.
Some times these slice and some times they dont. I attach one here that is avalibale free on thingverse https://www.thingiverse.com/thing:3223309
I know they are big files but it generaly crashes on adding supports. I know ita a large file but I am working on a CAD machine so plenty of resorces. Its a pity we are not able to slice these :(
