Unable to connect to printer, no serial port found. Printer was used for about 2 weeks(new), then sat unplugged for a few months. Now unable to connect to printer. Getting 'No working connection parameters could be found'.
What did you already try to solve it?
Reinstalling fresh Octopi
3 different USB cables
running dmesg
From what I could understand from the help guide on the issue, no. I can reply with the readout later as currently at work.
After initial post I also updated firmware to mriscoc’s most recent build. And tried plugging into computer to see if USB device was recognized, no luck.
I am thinking it’s a faulty port. I’ve seen a couple ideas of wiring directly from the main board to the Pi via gpio/serial. Could this be a solution instead of buying an all new mb?
Yeah for sure. If the board doesn't have dedicated serial pins, you can most of the time use the ones for the serial to usb converter.
Here is an example
sounds weird - running latest Octo on RPi4 on a stock 3S1Pro so the host commands are not enabled as discussed in so many forum posts - but everything works fine. Auto connect, load to SD or Pi and run jobs etc.
I am not a techie so no skills when it comes to doing anything other than plug it in and run.
