After updating Klipper (trough fluidd) and flashing the MCU, i get an mcu 'host': Command format mismatch: error

[olif0x]

Hey there, yesterday at around 3 am GMT+1 i've decided to update all components trough the Fluidd GUI.

1. Moonraker
2. Klipper (Errors started to happen)
3. afterwards OS Updates (to ensure that everything is up2date)

the first errors appeared, because in my pause, cancel makros it didn't accept the default_parameter_x commands: (this is out of the klippy.log - in my current makros.cfg those parts are already completely commented out as a workaround... so i dunno why the klippy.log still have these makros before the upgrade happened)

so i completely commented those macros out.

Afterwards i then got the error seen in the screenshot.

I prepared the mcuflash files for my skr-mini-e3-v2 with the following command:

pi@fluiddpi:~ $ sudo service klipper stop
[sudo] Passwort für pi:
pi@fluiddpi:~ $ cd ~/klipper
pi@fluiddpi:~/klipper $ git pull
Bereits aktuell. (already on latest version)
pi@fluiddpi:~/klipper $ make clean
pi@fluiddpi:~/klipper $ make menuconfig
  Creating symbolic link out/board
Loaded configuration '/home/pi/klipper/.config'
No changes to save (for '/home/pi/klipper/.config')
pi@fluiddpi:~/klipper $ make

And afterwards i did flash the mcu:

`pi@fluiddpi:~/klipper $ ./scripts/flash-sdcard.sh -f ~/klipper/out/klipper.bin /dev/ttyACM0 btt-skr-mini-e3-v2
Flashing /home/pi/klipper/out/klipper.bin to /dev/ttyACM0

`

And i've still got the error on the klippy GUI:

After the mcu flash i also did disconnect my 3d-printer from the power to let it completly powercycle.

(CR10s Pro v1 but with an skr-mini-e3 as the mainboard and a microSwiss Extruder)

I've attached all logfiles and my config-files maybe you could help me make my printer run again? :-) (They are all in the zip-file) I wanted to start a 2-day print :D

Should have had waited with that update :P ;-)

many thanks and best regards Olifox github_issue_klippy_log&config-files.zip

Update Klipper and MCU again. Also see https://www.klipper3d.org/FAQ.html?h=update#how-do-i-upgrade-to-the-latest-software

For the macros, replace

[gcode_macro CANCEL_PRINT]
rename_existing = BASE_CANCEL_PRINT
default_parameter_x = 0
default_parameter_y = 0
default_parameter_z = 10

by

[gcode_macro CANCEL_PRINT]
rename_existing = BASE_CANCEL_PRINT
gcode:
    {% set x = params.x|default(0)|float %}
    {% set y = params.y|default(0)|float %}
    {% set z = params.z|default(10)|float %}

Thx for your reply!

Ok, i've updated the makros and also Updated Klipper and the MCU again as in the steps mentioned (altough make flash doesn't work for me). Still no Luck :(

Why does it shop up 2 times with an host-entry? is there maybe a way to remove that fluidd entry?

• I've updated the MCU also with the KIAUH update Script and uninstalled installed Klipper, Moonraker, Fluidd, KlipperScreen multiple times....

I guess my only chance is to start from scratch :-( Logfiles: klippy (1).log

I guess u also use ur rpi as an mcu for input shaper. that also needs to be updated.

Yep, sorry, missed this one: Basically the message is quite clear: host and mcu have same version, fluiddpi is off

You need to build the linux mcu in make menuconfig

Yes that was it. I also had another friend looking at all those configs and just at the end he also mentioned it.

and now that i remember, when i first wanted to update the mcu i was wondering why linux processes where activated in make menuconfig :-D which i completely ignored and changed everything so that the printer board gets updated :D

well, lesson learned ;-) Printing works again (altough in the full end i just reinstalled fluiddpi to have a clean start and then updated the linux mcu as then came the hint in with the linux process). Then everything was working again :-)

Many thanks for the help!
