Since completing assembly, I have been struggling with inconsistent response from the device. When I use RepetierHost to try to talk to the printer, it does connect but printer type reports "Unknown" and no commands from Manual Control have ever received any response. All commands are still in a "waiting" state. The extruder position shows in red, meaning that it is unknown.
I fear that my main board is dead on arrival, but I'm way past the 7 days when IAP will replace it.
