Stuck at Status "Detecting Baudrate"


-Setting Up OctoPi (First Timer) (Linux Noob)
-Got past the "Unable to connect to serial port" error by adding the AMA* Glob
-First and subsequent tries after getting through Serial Port connection, the Auto Baudrate attempt fails - well it doesn't really fail just says "Detecting Baudrate" as the status until I disconnect

No idea what to do next.

OctoPi image used today Ver 0.15.1 on a Pi 3B
OctoPrint Ver: 1.3.10
Server notified me there was an update and I did that install

The webcam is working on the server

/dev/ttyAMA0 is most probably wrong, that's the Pi's own serial interface, not your printer. If OctoPrint doesn't see your printer it means it either registers a non standard USB device or is not detected by the underlying OS at all.

Take a look here and provide some more logs, in this case the contents of /var/log/syslog or simply calling dmesg before and after connecting your printer might go a long way.


The device should most probably be "/dev/ttyUSB0". Find out existing devices with "ls -l /dev/ttyUSB*".
