Printing doesn't start (resolved)  

Printing doesn't start (resolved)

I'm trying to print something I made. I've made and printed a bunch of things. This particular model, sliced in Slic3r Prusa Edition, looks fine and produces perfectly normal g-code. When I try to print it it never starts, never changes the current bed state(doesn't turn heating on, doesn't turn heating off), never calibrates but the SD% moves slowly up, like it's reading the SD card & printing, but it's not doing anything. I've tried various settings in Slic3r but I always get the same result.

It's just this one model I have problems with, everything else prints fine. It is a pretty thin model, but slic3r preview shows the paths and they look fine.

Here's the initial g-code to see that it looks normal to me:
