You know, I believe what I read too much and don't experiment as much as I should. I read somewhere that the minimum layer for our printer was .16 and I've never gone thinner. I'm so glad that you've opened my eyes. I need to push the limits more. I mean, for the most part what's the worst that will happen, I'll waste some plastic? I'm going to do a super nice print of something at .1mm. Glad to hear that you've even gone thinner. I'm assuming at that thinness your E-Steps need to be really, really close.
