Manta M4P + CB1 Multiple MCU?

Basic Information:

Printer Model: Sidewinder X2
MCU / Printerboard: Manta M4P + CB1

Hello everyone,
I was wondering if i need to specify the [mcu CB1]
MCU are etup like this in my config.cfg
serial: /dev/serial/by-id/usb-Klipper_stm32g0b1xx_53002B001150415833323520-if00
[mcu CB1]
serial: /tmp/klipper_host_mcu

But with putty, i can’t fin the path mentionned for the CB1 serial, i’ve searched the internet, and didn’t find any answer

Thanks in advance (44.5 KB)

Please next time include klippy.log file - it always contain your whole configuration and logs.

In your current config I didn’t found any usage of [mcu CB1] - so it’s not needed.
if I wasn’t lost in that pile of files (because you didn’t include klippy.log).

You can’t find that /tmp/klipper_host_mcu because most probably you didn’t deploy “Linux MCU” in your CB1 module.

You still can add “Linux MCU”’ if you wish to monitor some status of your CB1 module.

Hey thanks for answering, here is the klipylog, i thought it was in the file provided

How can i add linux MCU ? Still fairly new with klipper, doing my research but not getting what i’m looking for

klippy (2).log (370.3 KB)

This is only needed if you want to directly connect some non-USB hardware, e.g. an ADXL board, to the host SBC or if you want to use some of its GPIOs for whatever purpose. If you do not have such a use-case, then no need to bother with it.

See RPi microcontroller - Klipper documentation

Thank you very much
