Not sure about the square waves either, but it might be worth a try. Two PWMs, with "isolating" diodes maybe?

"luckily" no action shots from the party haha.. Great fun though

(Well worth the evening throwing it all togheter)

The Go survived the whole ordeal and ran flawless the entire evening, not even a glitch.

I did erase prior to reflashing just to make sure that wasn't the issue. What is strange is when I start Visual Studio, the first time I build/debug the project it works fine. If I make a minor code change, rebuild and debug, I get the error posted. If I physically unplug the Go from the USB power and re-connect, the code runs. It seems like whatever soft reboot is taking place is causing the problem.
