First time I ran a print on a alpha, I noticed that the display was reading a filament run out but cura was still sending it commands and it was still printing. The print was stopped and resent, this time no run out filament was detected. I noticed this is big because the connecter with the green wire is hooked up to the filament going to the E2 extruder.
Also I noticed that the console keeps displaying this message.
[14:16:39] echo:Unknown command: "M73 P56"
