Simple example, two cubes, two processes, one at 0.2, one at 0.3. Prepare print with both processes, applying one process per cube and then print.
Does this work?
It didn't complain when I tried, but the layer display seemed to keep the two models in step, so I didn't bother printing it...
Re: Can two different layer heights print at the same time?
It does work, if you look at the finished preview of them, you'll notice the cube with .2 probably has a noticable amount of more layers than the .3 cube will have. And if you look through the G-Code, it will probably step down the Z slightly at some points
