Troubleshooting

Error during homing z: Eddy current sensor error

You might need to adjust your reg_drive_current, for more details: https://github.com/bigtreetech/Eddy?tab=readme-ov-file#sometimes-i-get-error-during-homing-probe-eddy-current-sensor-error

MCU Protocol Error - mcu 'eddy' Unknown command: debug_read

If you get the following error, it means that the eddy is not connected to the printer. This is either because its physically not connected, the wiring is wrong, the usb subsystem has disconnected the eddy during a restart or the serial id is wrong

So from ssh run a lsusb and make sure you can see:

If you cannot see it in lsusb, then it very likely means either the eddy is wired incorrectly, or if was working, it just means that an attempt to restart the eddy failed because the K1 refused to recognise it, there is no recourse except to restart the host via Fluidd / Mainsail (or power cycle the printer)

If you can see the eddy in lsusb, then you should try to update the serial (see next)

Manual BTT Eddy Serial Device configuration

You can run the following command to fix your serial if you forgot to plug your btt eddy in during the installation or update:

~/pellcorp/k1/installer.sh --fix-serial

Note

If you run the above and receive an error like:

```
root@K1Max-AF34 /root [#] ~/pellcorp/installer.sh --fix-serial
-sh: /root/pellcorp/installer.sh: not found
```

It means you are on an older version of Simple AF and you should instead use the old style commands:

```
/usr/data/pellcorp/k1/installer.sh --fix-serial
```
