I uploaded the firmware. Will let you know if I see any more spazzing.

Fair enough, thanks for the explanation.

Of course I don't get the error I want. I'll try again tonight.

It might be different on OS X/Linux. I find it easier to run pronterface on linux since it requires the least dependencies vs repetier host (python utilities vs mono and monodevelop), and its a really easy install on OS X (all the python utils are preinstalled so its just execute the .app package). Not sure how it is on windows since I only use it for gaming.
