OctoPrint won't connect to my M3D Micro

[VargurErikson]

Hello Donovan,

I've installed OctoPrint on a Raspberry Pi 3 with M33 from your Github site (because the Plugin-Repository didn't work)

When i try to connect to my Printer the follow Entry are in the Monitoring Terminal:

Changing monitoring state from 'Offline' to 'Detecting serial port' Connecting to: /dev/ttyACM0 Changing monitoring state from 'Detecting serial port' to 'Opening serial port' Connected to: Serial<id=0x6e125e30, open=True>(port='/dev/ttyACM0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=None, xonxoff=False, rtscts=False, dsrdtr=False), starting monitor Starting baud rate detection Changing monitoring state from 'Opening serial port' to 'Detecting baudrate' Trying baudrate: 115200 Send: N0 M110 N0125 Baudrate test retry: 4 Send: N0 M110 N0125 Baudrate test retry: 3 Send: N0 M110 N0125 Baudrate test retry: 2 Send: N0 M110 N0125 Baudrate test retry: 1 Send: N0 M110 N0125 Baudrate test retry: 0 Send: N0 M110 N0125 Changing monitoring state from 'Detecting baudrate' to 'Offline' Changing monitoring state from 'Offline' to 'Error: No more baudrates to test, and no suitable baudrate found.' Connection closed, closing down monitor

do you have any idea?
