Hardware is a Pi4, 4GB. I've looked through the log, don't know how to upload file here for you to look through it, and it's too long for character limit. It does indicate issues with the serial port, either permission denied in the case i tried tty0 symlink, or no such file or directory when going strait to the serial/by-id.
I've tried many setups. First was following https://www.klipper3d.org/Installation.html#obtain-a-klipper-configuration-file With octopi. Next was another guide that I can't seem to find the link to again. But was a default raspbian lite x32, and installing klipper and mainsail on top with kiauh. next was this guide https://www.obico.io/blog/install-klipper-ender-3/ which I modified for the Ender5+ (what processor to compile for)
I've had varying success, initial try the USB wouldn't show in serial/by-id, I swapped cables and still had no entry. Swapped cables back and tried the next guide/OS, and that gave me the entry in serial/by-id.
also I Tried using the symlink tty0, but that didn't work either.
For the current OS/Setup I think i've messed with too many things, and just need to start over from fresh OS. But I can't think of anything different to try.
Since you mention permissions/access denied, have you given your user permissions to use serial? You can do this with:
sudo usermod -a -G dialout $USER
What is the output of:
ls -al /dev/serial/by-id/*
This is likely the problem. I'll try it when I get off work.
Thanks!!
Thank you for pointing me in the right direction.
Pi Imager lets you option for a username change. I changed it originally, and mainsail is setup for "pi" user normally.
I reflashed with pi Imager, without changing username, and it all is working now.
Awesome, I’m glad you we were able to get it solved and it get everything back working.
I forgot you will also need tty access, so you'll also need to do:
sudo usermod -a -G tty $USER
After that you will need to relogin in order for the changes to take effect. I'd say just to reboot so you know everything is reloaded with:
sudo reboot now
These are all of course assumptions based on your mentioning permissions, and without any logs to verify. If you decide to go with the nuclear option and redo the OS and setup I'd recommend looking at using https://github.com/th33xitus/kiauh. It will allow you to setup Mainsail, but also you can try other front end options as well. Just something to consider if you decide not to continue troubleshooting and opt to start over.
