You most likely missing a module that you had previously installed

z_calibration is no default klipper section, therefore it's not valid. As it worked previously you most likely had a custom module installed. A quick google search brings up this project: https://github.com/protoloft/klipper_z_calibration
No idea if it's the correct one

@quartz stratus don't delete the original message. You can just click on the 3 dots top right and close it. That way the post won't be useless in futute

Whoops - sorry Mr Yel - you were correct - I installed the missing z_calibration and it got past that error - now its looking for PAM - not sure if thats built into klipper now

Here are all the official klipper sections listed:

Thanks - yeah there's no PAM in there. I'll delete it for now

The official klipper sections dont include
[mcu rpi]
serial: /tmp/klipper_host_mcu
which was in my old printer.cfg, and is where I am now stuck:
.
Klipper Log file says:
mcu 'rpi': Unable to open port: [Errno 2] No such file or directory: '/tmp/klipper_host_mcu'
Is this [mcu rpi] sectrion redundant?

[shy sage]

Looks like you were using the RPi as a secondary mcu.
