Having issues getting input shaping setup. I cannot get passed serial mcu must be specified. spent the last few hours going through the below linked klipper docs.

klippy attatched. thanks to any and all that take the time to look at this!

It looks like you deleted the [mcu] line from your config by mistake. The lines below are what Klipper is seeing in your config file.

[fan]
pin = PA0
serial = /dev/serial/by-path/platform-5200000.usb-usb-0:1.3:1.0-port0
restart_method = command

Change it to this:

[fan]
pin = PA0

[mcu]
serial = /dev/serial/by-path/platform-5200000.usb-usb-0:1.3:1.0-port0
restart_method = command

You nailed it! Thank you! If 3d printer firmware configuration has taught me anything its that any errors or problems are always my fault…(he says after wiping the tears of disgrace and frustration off of his face)
