Serial Port Issue

Get Help
1

In Octoprint the only serial port drop down is auto. Supposedly i'm supposed to get /dev/ttyUSB0.

**I've tried different USB ports and used a web cam successfully in all ports and also tried just the printer plugged in without the web cam but still nothing will show up. I have used two different cables with no luck and today even bought a brand new cable with same result.

I tried to manually use /dev/ttyAMA0 and that actually says connected but then tries to auto detect the Baudrate but just freezes so i tried 115200 baudrate and that just fails. been googling all sorts of things and trying but no cigar.**

running RasPI 3 B+ and attempting to set it up with a CR10. (OctoPrint version 1.3.10, OctoPi version0.15.1,

Disconnect the USB-based webcam. I'm guessing that you're trying to make OctoPrint think that it's talking to a printer when it's talking to a webcam instead.

ls -l /dev
# unplug the webcam
ls -l /dev
# note what's now missing

# now unplug the printer's serial
ls -l /dev
# note what's now missing

Im actually wondering if it is to do with FTDI drivers ?
so i tried this guys fix but doesn't seem to work.

"pi@octopi:~  $ sudo modprobe ftdi-sio
  pi@octopi:~ $ sudo chmod 666 /sys/bus/usb-serial/drivers/ftdi_sio/new_id
  pi@octopi:~ $ nano /sys/bus/usb-serial/drivers/ftdi_sio/new_id

and insert "0403 8a8a" without the quotes, hit ctrl+x and save
Plug out your printer, and plug it back in.

pi@octopi:~ $ ls /dev "
9

Okay, so your webcam appears to present itself as /dev/video0 then. In theory, it looks like the second serial device /dev/ttyAMA0 is likely the printer... or is it? It still shows up after you've pulled the printer.

An alternate approach is to disconnect the printer's serial, boot up the Raspi and do a dmesg. Plug in the printer's serial cable and repeat the dmesg, noting what new messages appear. This might help to confirm/deny the rumor that ttyAMA0 is your printer.

after it is pluged in
12

apparently the same i believe, i also tried to plug printer into PC and i still can't pick anything up because i think it is also needing the FT232R USB drivers ect.

13

Plug in the printer and try for an lsusb command.

Yeah, that's what I was worried about. The Raspi definitely cannot talk to the printer. At this point, I think I'd hit up the CR10 support forum to find out what this is going to take. Maybe something's not setup correctly on the controller board or there's a jumper missing or something I wouldn't know.

17

ok thanks for your help mate.
