I chose to run my e3v2 today, but Klipper crashed, so I’m reinstalling it. Everything seems set up right, but it’s showing ‘mcu’ can’t connect and asking for printer configuration help.

Find the MCU details in your printer.cfg file. The serial interface for your MCU is listed as [mcu] serial: /dev/serial/by-id/usb-Klipper_stm32g0b1xx_35004A0011504B4633373520-if00. This is specific to your setup; others will differ. From the SSH terminal on your Pi, run ls /dev/serial/by-id and enter your Klipper address.
