Basic Information:

Printer Model:
MCU / Printerboard:
Host / SBC
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…sovols07
it is not wanting to connect to the MCU While it was in the middle of a long print it stopped and said something about an update failing and to press firmware restart well i accidentally did reboot and it ended up stuck in the boot mode but i reflashed it and it was able to connect to the mcu and as soon as i started leveling it again it lost connection to the mcu ive looked everywhere for a solution. idk what to do. heres my klipper log
klippy (1).zip (11.2 KB)

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0'

The key part is No such file or directory: '/dev/serial/by-id/usb-1a86_USB_Serial-if00-port0'
Apart from the worst case, a defect board, you will likely find your reason here: Issues flashing the printer board
