mcu unable to connect
I have been struggling with this for a few days now and cannot find a solution anywhere. i have tried new usb cables, tried reflashing the board a few times using both methods (usb and sd card). Firmware. bin changes to .cus after flash. Checked the mcu serial number and that is correct. Reinstalled MainsailOS on the Pi and went thru the whole setup process twice. Nothing fixes the problem. i sure hope someone has the answer to this because it is driving me nuts. Here are the files If you need anythiing else let me know.

There is a known bug in udev which leads to not enumerated /dev/serial/ devices. Maybe you are affected by that. Did you run a full systemupdate?

quartz glade
#

yes I did. any way to get around this?

Yes, but we officially don't provide the solution atm. There is a solution on the klipper Discord, pinned in the general chat and I reposted it here in a thread with the same problem once. Please look out for it yourself as I don't feel comfortable enough with that solution to repost it over and over again, as I don't understand every aspect of the command myself.

Yes that would work or you wait an day or 2. We hope that Debian cleans there mess and send an update of the udev package

Kwad also posted in the general chat that it seems like MainsailOS v1.1.0 should be fine and MainsailOS v1.1.1 makes problems.

Can you send ls /dev/serial/by-id

You messed up something inside your printer.cfg xD

#

You wrote /dev/serial/by-id/stm32f446xx_28002C001850344D30353320-if00 instead of /dev/serial/by-id/stm32f446xx_2B002C001850344D30353320-if00

#

So you wrote 8 inside your config but it should be B according to your output
