Cannot get to work - Githubissues

I have built the hex file (with a few modifications to how the m2u8 library builds) and I can upload it successfully through an arduino board using the stk500v1 programmer. When I plug it in and turn it on, it homes the motors and shows the FreeExpression text on the LCD, but none of the buttons work and I can't get it to do anything when I try to send it InkScape commands.

@ellisgl Do you have any idea on what could be the issue or how I could debug what the issue may be. Are there any ways I can look at the startup logs using the arduino? I'm hesitant to plug the arduino into my computer while also feeding AC power to the device.

Any thoughts would be helpful! Thank you!
