Hi.
I have an EddyDuo sensor connected in CAN mode, and it works well.
When I try to calibrate the temperature compensation after accepting the first calibration step (before heating), I get an error: Internal error on command:“ACCEPT”
When I switch the EddyDuo to USB mode, I get the same error again.

temperature_probe btt_eddy: calibration aborted
Internal error on command:“ACCEPT”

Hello @Virtual77 !

At first you might update the Klipper version on the CB1:

Is this klippy.log an excerpt? I’m missing the startup at the beginning.

I’m attaching a new log

klippy.log (4.6 MB)

Yeah, it should be fixed soon.

Thanks,
-Timofey

Now we know that people do thermal compensation :smiley:

Fixed

5

How do I update Klipper to CB1?

6

make menuconfig

[*] Enable extra low-level configuration options
    Micro-controller Architecture (Linux process)  --->

make flash

Done.

Not strictly necessary, but it can be updated that way.

After installing version v0.13.0-515, everything on the MCU and CB1 started working. Thanks
