Can´t connect to printer: "Detecting serial port" to "Error: Failed to autodetect serial port, please set it manually."

What is the problem?
I had a break in printing for a while now (3 month). Now i started again and want to move my printer in my "lab" and build an enclosure. Three month ago printer worked well. Now after moving it (and changing one buck converter) for the raspi, octopi does not recoginze the printer.

What did you already try to solve it?

  1. Checked cable stuff twice

  2. replaced the new buck converter with a 5.x volt adapter -> no change

  3. Updated OctoPi to 1.3.11 (had some assumption about corrupt setting- but was not)

  4. Tested in safe mode

  5. searched different forums and found stuff, but did not really help (e.g. https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=110164 whre i was not sure about how to detect a hardware issue). Tried to set serial port manualy (change baud rate, can´t change port. There is only "auto available). Topic Failed to detect serial port seems identical, but no solution/answer there)

  6. Changed USB Port for the connector cable to printer

  7. Tried with printer off/on to see if different error messages occur (found no diff). So assumption is, it is something around the raspi and not the printer.

  8. Played with voltage regulation 5.1/5.4V - no change

  9. Changed connector cable...no change..

  10. now writing this entry in hope for some tipps what i can look into...

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ...)

Printer is an ender pro 3 with THD firmware. Raspi is V 3.b

The underlying operating system isn't even seeing your printer. You need to figure why that is and fix it first before you can expect OctoPrint to be able to connect to it.

Search this forum for "failed to autodetect" and "dmesg". Also

Hi foosel,
dmesg gives me that output:
I just checked the input voltage again..my voltmeter says 5.10 V on the output of the buck converter. And only some 10cm in between it and the raspi.
Adjusted it now to 4.8 V, but still the same dmesg outcome "over current"
Removed usb cable from raspy to printer - no change.


OctoPrint version : 1.3.12rc1
OctoPi version : 0.16.0

The Raspberry Pi does not supply enough current to power the 3D printer through USB. You either need to get a USB cable that does not have a power lead (data only), or leave the USB cable between the power supply and printer disconnected until both raspberry pi and the printer power up completely. This will take care of the USB over current messages listed by dmesg.

If the server still starts in safe mode, try disabling all the plugins. If that restores functionality, re-enable the plugins one at a time until you find the offending one.

Hi Snargaloo,
sadly that´s not the prob. I have those messages even, when the raspi is running without any usb cable pluged in or like you said, both powered up and then do the connection.. And also plugins are not the cause. I currently suppose the hardware (raspi) to have the prob, but i don´t know how to check it by measuring it. Anyway, thank´s for replying !

Do you have anything connected to the GPIO pins on the RPi? If so, please list.

Following this as I'm having a very similar issue after not printing at my office for a month or two. Nothing changed and I couldent even get my Pi online so I rebuilt it and now I cant get it to connect... :frowning:

I see you are running an older kernel. Are you still on stretch, or have you updated to buster? If you updated, did you update the firmware too? If not try: sudo rpi-update

No. Don't do that.

sudo apt-get update
sudo apt-get -y upgrade

The one you recommended pulls from the devel branch and the one I just have shown pulls from the master branch.

Yes, i checked rpi and decided against it and did the update/upgrade.
That worked fine.
But still dmesg gives the errormessages.
Currently i cant access octopi from browser as i cannot start the service. I am investigating it, but i doubt the upgrade solved the prob. [solved prob with running server, but still no connection->tested next rc2 prob still there.--> i will now go to hardware level again to check it volt on pins..lets see.]
cu

GPIO PINs are unused.

Did you make any change that would get rid of those over-current log entries? Because that to me seems like it's not a good situation to allow in your system.

If i could find the origin of that messages, i would do so.
Powersupply seems not to be the cause.

When I upgraded from stretch to buster, I was having trouble with the USB ports, after switching the kernel to the proposed branch, USB functionality was restored.

If you boot the RPi from power off and nothing connected to USB ports or any of the header pins, do you still get over current messages? It would seem you have something connected that is drawing too much current. A webcam, fan, display, ...

I solved some similar problems by using a 3 ampere power supply.
Did you measure your power supply voltage when the Pi was using power? The voltage can be higher with no load.

Hi,
after some more installationtest with "beta" and new release and config stuff, i tried with hardware. I bought a new pi, connected to same powersupply and with same sdcard (OS). No errormessage about voltage no more. So the root cause was a defect rasp board in my case.

Due to all installation stuff webservice is currently not running and some more error messages occur..i need to check, if i would like to fix them manually, or do a fresh reinstall of all. Thank you here for replying and giving advice on that topic.
