issue:
I have recently gotten an ender 5 plus and an skr mini e3 v2 to accompany it. i haven’t been able to get it to work and i keep getting the following error with fluidd:

mcu ‘mcu’: Unable to connect
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer

everything other then the board is stock. and the serial for the mcu is the same as the one i get from Putty.

Hello @Dusty !

Can you try again uploading the klippy.log?

You may check for the correct firmware on the printer.
Also check for proper powering of the printer.

i remade the klipper.bin and put it in the sd card as firmware.bin which was then changed to firmware.cur, which gave me the same result.

I also checked the power supply and the connections made to the board etc. i also swapped out the cord for another one which i know works, which gave me the same result again…

Any suggestions? thanks.

# This file contains common pin mappings for the BIGTREETECH SKR mini
# E3 v2.0. To use this config, the firmware should be compiled for the
# STM32F103 with a "28KiB bootloader" and USB communication. Also,
# select "Enable extra low-level configuration options" and configure
# "GPIO pins to set at micro-controller startup" to "!PA14".

# 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.

did you make to firmware with the above settings?

Did you add this to your printer.cfg file ?

serial: /dev/serial/by-id/usb-Klipper_stm32f103xe_33FFD8055641343421832043-if00

Hey, sorry for being Late with this but i found some time to go though the voron setup until the configuration and i am getting the same error message i got from last time.

Its possible that i have incorrectly set up the configuration, or that there is some kind of issue between the pi and the printer… either way not much is different from last time but i’ll post the new klippy log after this.

Thanks.
