I am new to RP stuff and yesterday everything was working fine on my 4b. I have it set up to run my 3d printer, Artillery Sidewinder x2. The problem has risen that when i connect Octoprint to the printer, it does identify that 'serial port cannot be found'. I was able to move the printer with Octoprint, but not now. Any guidance would be appreciated to help fix this.
RP returns this in Terminal on Octoprint.
Changing monitoring state from "Offline" to "Detecting serial connection"
Performing autodetection with 0 port/baudrate candidates:
Changing monitoring state from "Detecting serial connection" to "Error"
Changing monitoring state from "Error" to "Offline after error"
What did you already try to solve it?
Tried the suggestion too increase timeout etc in Octoprint
Have you tried running in safe mode?
Did running in safe mode solve the problem?
You can download this in OctoPrint's System Information dialog ... no bundle, no support!) octoprint.log (151.6 KB)
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
Check that your Pi can see the printer with some of the troubleshooting steps above, and that it is powered on & the cable works properly. Every time you try and connect there is no serial port available for it to connect to, the OS is not giving it any candidates to try.
Charlie definitely the RPi as i have tried 3 new serial cables today and none work. I linked the printer through pronterface and the serial port works on port 115200 on my Mac and it recognises the printer. I can home it with pronterface. i have ssh dmesg -w into the RPi and this what i get back:
To confirm, did you plug the printer in after you sent dmesg -w?
Can you check with another USB device that you can see something, to confirm the USB ports are working properly? Any USB device, a mouse, keyboard, webcam, etc. You should get some output appearing if you leave the dmesg -w command running while testing everything.
checked the ports with a USB mouse and still nothing happens. The mouse flashes momentarily and then goes off. Nothing appears in dmesg -w. I ran the command and and connected the printer.
Also plugged a card reader in and that lit up but no movement on dmesg -w.
What was strange that AutomaticShutdown was giving errors for indentation, but the latest release of the plugin lists that being fixed by @kantlivelong. Looking back at your log you provided you were one version behind at 0.1.4.
