mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/btt-octopus-11: [Errno 2]
So, i have a octopus pro 446 board that i've reflashed using the RatOS configure a couple of times but this error keeps popping up.
the weird thing is, I can home my printer, heat up the bed, hotend and everything. but when i start a print it goes through all the steps (leveling etc) but when it wants to actually start pritning it moves to the outer edge of the bed for the purge line and then it just throws the error ''Lost communication with MCU 'mcu''' this is -consistantly- repeatable

It is, most likely, solved.
I tried everything, different PI, usb cables, rewiring etc.
What was the cause? The power brick that is in the wall socket that supplies power to the printer. I changed that one out and was able to do some test prints.
