"Error during homing z: Eddy current sensor error" after updating to mainline klipper

I saw that Eddy is now supported in mainline klipper so figured I'd update everything with the hopes of it resolving some of my z-offset issues.

After rebuilding and flashing klipper for all of my devices (BTT Manta M8P V2.0, BTT EBB SB2209 CAN (RP2040) with Knomi and SB toolhead, and Eddy) and going through configuration steps 1-21 then trying to home for steps 27-29 I receive the following errors:

4:04 PM Error during homing z: Eddy current sensor error
4:04 PM Error during homing z: Eddy current sensor error

Here's my updated [printer.cfg](https://gist.github.com/cjhmdm/d26374865b635cb2fdd06b007634cb93) and [eddy.cfg](https://gist.github.com/cjhmdm/acd87ccfaac0bf66ba23cdc790e788aa)

Review the linked printer.cfg and eddy.cfg, then reproduce Z homing after configuration steps 1–21 and homing steps 27–29. Compare the resulting logs with the reported “Eddy current sensor error”; done means identifying a reproducible configuration or firmware cause and confirming that Z homing succeeds.
