Error Message "The value 'fan2' is not valid for FAN"

Sovol SV08
1

Printer was working great, had about 100 hours on it. Upgraded to the Sovol Eddy Sensor kit following all the instructions and even watching a few videos first.

After rebooting and trying to start a print (any print) I get the following error and then the job cancels “The value ‘fan2’ is not valid for FAN”

I’ve done searches throughout the config but cannot see any reference to a fan2. Where should I be looking to correct this issue as I haven’t found anyone with the same problem and a solution.

The actual configuration used at print time has any [include] spliced in. In your case I think you need to look in macro.cfg to find the “fan2” reference.

The simplest way to debug is to download klippy.log from your printer and run it through
https://sineos.github.io/Klipper-Advanced-Log-Inspector/#configs

Having the entire configuration in one chunk simplifies finding errors. The downside is you’ll still have to open xxx.cfg to edit.

Thanks. I didn’t see any reference to FAN2 in macro.cfg however I found fan1 and fan3 in printer.cfg. I tried a few edits and what finally worked was changing “fan3” to “fan2” and then I no longer received the error and was able to resume printing.

I still don’t know where the reference to fan2 is coming from.

Appreciate the assist.

Assuming you are using Orca Slicer, try this:

Edit Printer settings

On the Basic Information tab, scroll down to Accessory and make sure “Auxiliary part cooling fan” is not checked.

I hope that helps.

I think it is an error in the update manual. The motherboard fan is fan1. I have just added the sovol eddy and used fan1 for the motherboard fan. Working fine.
