How to help. Temps from Octupus MCU and EBB36 mcu

General Discussion
1

I am trying to read the temperature from the EBB36 mcu and Control a fan for the Octopus mcu temp sensor. See comment on EBB36 sensor_mcu line. From the documentation and forum posts I am reading, this is the correct way to do this, but I cannot get it to work.

The following give me unknown pin EBB36

 [temperature_sensor EBB36]

sensor_type: temperature_mcu

sensor_mcu: EBB36 # Causes Unknown Pin and if commented out get pin ADC_TEMPERATURE used multiple times in config

min_temp: 0

max_temp: 100

This is the whole section that has the fans and temps for MCU temp reads.

[temperature_fan BTT_Octopus] # Electronics fan PWM

pin: PA8

max_power: 0.60

hardware_pwm: true

control: watermark

max_delta: 2

sensor_type: temperature_mcu

min_temp: 10

max_temp: 80

target_temp: 40

[temperature_fan Raspberry_Pi] # Electronics fan PWM

pin: PE5

max_power: 0.60

hardware_pwm: true

control: watermark

max_delta: 2

sensor_type: temperature_host

min_temp: 10

max_temp: 80

target_temp: 50

[temperature_sensor EBB36_temp] 

sensor_type: temperature_mcu

#sensor_mcu: EBB36

min_temp: 0

max_temp: 100

In what way? Error messages?

Maybe the klippy.log (it was asked for) can help.

Please attach it yo your next post.

BTW: Please try to avoid empty lines in the code snippets. :wink:

The error is in the description in 2 places. I am pretty sure I am doing something wrong with the way I wrote it, and I need someone to look it over and see if they can spot my error. Not sure what you are going to find in the klippy log, since it is a printer.cfg issue. But here it is.
klippy(1).log (6.4 MB)

# Causes Unknown Pin and if commented out get pin ADC_TEMPERATURE used multiple times in config

  • That is no error message, that is a note.
  • It only appears in the config, not in the log.
  • This macro: [temperature_sensor EBB36] does not appear in the log.
  • There is no error in the log

klippy(2).log (7.8 MB)
Here are the errors. I rolled over the logs and reproduced the errors I am getting.
This is with this is the printer.cfg

[temperature_sensor EBB36] #the EBB36 can be any name you want as long as it doesn’t match any other named device.
sensor_type: temperature_mcu
sensor_mcu: EBB36
min_temp: 0
max_temp: 100

And this it with this in the printer.cfg

[temperature_sensor EBB36] #the EBB36 can be any name you want as long as it doesn’t match any other named device.
sensor_type: temperature_mcu
sensor_mcu: EBB36

max_temp: 100

Have you searched the config for the multiple use of ADC_TEMPERATURE?

Yes no duplicates.

I just figured it out. I was giving it the wrong name. It was supposed to be EBBCan instead of EBB36. Everything I read said you could name it anything you want, but you have to name it the same name that you defined for the MCU.

[temperature_sensor EBB36] #the EBB36 can be any name you want as long as it doesn’t match any other named device.
sensor_type: temperature_mcu
sensor_mcu: EBBCan
