hi, after a quick look your dev id looks weird, normally it looks like that or similar: serial: /dev/serial/by-id/usb-Klipper_Klipper_firmware_12345-if00

Try to reflash the board again with the settings described in the config for the skr mini e3.

The firmware should be compiled for the STM32F103 with a "28KiB bootloader". Also, select "Enable extra low-level configuration options" and configure "GPIO pins to set at micro-controller startup" to "!PC13".

The "make flash" command does not work on the SKR mini E3. Instead, after running "make", copy the generated "out/klipper.bin" file to a file named "firmware.bin" on an SD card and then restart the SKR mini E3 with that SD card.

i think my id is right. [mcu] serial = /dev/serial/by-id/usb-Klipper_stm32f103xe_35FFDB053043553524770651-if00 restart_method = command

it works sometimes, but something i have this connection errors.

that's exactly how I installed it

I'm having the exact same issue with the SKR Mini E3 V1.2. Applied the same method several times, with different sdcards and usb cables...

I recommend you upgrade to the latest version of Klipper (see the FAQ for upgrade instructions), then add restart_method: cheetah to the mcu section of the config, then do a full power restart of both printer and rpi. If the problem persists after that, please attach the Klipper log file from that attempt.

EDIT: Strike out wrong advice.

KevinOConnor commented 4 years ago

Sorry, I got the printers mixed up. My previous advice would only be for a cheetah board, not the skr boards.

I've seen reports of USB reconnect failures on the mini-e3 and similar boards. It is not known the root cause of the issue - my best guess is problems on the bootloader that comes with the board. The only known work around is to reset again (possibly via manually resetting power to the board) until it comes back up.

I'm going to close this as it looks like the conversation has concluded.
