I am going through the motions prior to getting up and running but one thing stumps me.
I open Pronterface then click "settings" to open Slic3r settings. If I then, for example, select 0.1 for layer height (default is 0.4) and save it as, say, "test", it will do so. But if I load an STL file in to pronterface and select the "test" config, the machine will still start the (simulated) print but still uses a 0.4 layer height. Even if I change that parameter immediately prior to a test print it still defaults to 0.4. What am I missing here?
