Second MCU address for temp sensor

General Discussion
1

In my printer config I have a second MCU defined as shown below.
When I setup the first MCU’s temp I can see it in fluidd.
I can’t figure out how to point to the second MCU’s temp.

[mcu XBRD] # This is the second MCU
serial: /dev/serial/by-id/usb-Klipper_stm32g0b1xx_1C0050000250414235363020-if00

[temperature_sensor mcu_temp] # Works
sensor_type: temperature_mcu
min_temp: 20
max_temp: 70

[temperature_sensor XBRD_temp] # Does not work
sensor_type: temperature_ ???
min_temp: 20
max_temp: 70

Thanks

Please post issues and problems into General Discussion. Thank you.

Basic Information:

Printer Model:
MCU / Printerboard:
klippy.log

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed
Be sure to check our Knowledge Base and in particular this and this post

What does that mean. Error, crash… ?

Sineos, Thanks that worked.

I had read the Configuration reference [temperature_sensor] before posting but I still don’t understand what " sensor_mcu: XBRD" is. Is it a pin assignment, virtual pin assignment? I don’t see anything in the pin aliases in the config file. I notice that the first MCU doesn’t need it to work.

EddyMI3D - this is a syntax question. My printer.cfg file would not load or load and point to the wrong temp depending on what I was trying. My klippy.log was to big to attach without zipping so I just copied the pertinent part of the config file.

The [mcu] section is always Klipper’s main MCU and does not need any further mentioning in the config. This means all pins, settings etc that do not explicitly mention a MCU relate to this

Any other MCU needs to be named and referenced as such. Also pins etc need a reference to such a MCU.

Like fan1 vs XBRD fan1.
Thanks for the help.
