Basic Information: Printer Model: Voron v0.1 MCU / Printerboard: MKS SGEN L v1.0 Host / SBC : Linux Debian 12.10 AMD A4-7300 dmesg.txt (428 Bytes) lsusb.txt (1.7 KB) Describe your issue: I’ve got an older MKS SGENL v1 Board from a friend, but I’m unable to obtain the mcu id of the device. After flashing the klipper firmware id doesn’t show up under /dev/serial/by-id/ so I tried different USB ports, different USB Cables and even another PC. Output of dmesg and lsusb is always the same. I also tried the firmware from the makerbase github: [Klipper-for-MKS-Boards]/[MKS Sgen l V1]/firmware v0.10.0-557.bin flash via SDCard seems to work: firmware.bin is always renamed to firmware.cur but it is still not detected. What could I do next?

Hello @violentstorm ! Have you tried ls /dev/serial/by-id/* ?

Hi @EddyMI3D, thanks for your advice, but there is no such path: root@cubic:/mnt# ls /dev/serial/by-id/* ls: cannot access '/dev/serial/by-id/*': No such file or directory

Then either the MCU is not properly flashed or the connection from the host to the MCU is not working.

So what could be the problem during the flash process?
