As long it does not appear here: [https://www.klipper3d.org/Config\_Reference.html](https://www.klipper3d.org/Config_Reference.html) it’s not valid. What do you want to achieve with that command? What is it supposed to do? Where have you got that information from? ---

Hi, Sorry for not explaining it well. I am getting this error in klipper after updating all the software, it’s preventing printer from operating. I’m guessing that phrase is no longer used because ![IMG_0375](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/0/3/03789039fdd1eb80f976c1279f19189110ab443f.jpeg) ![IMG_0377](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/a/f/af2bdfb49eb6300316073a13c83a8bb9b53212cf.jpeg) I don’t see in printer config. The last time I used printer was a couple of years ago. Thanks for replying ---

As you noticed yourself: This is due to an (unsupported) 3rd party modification - [GitHub - protoloft/klipper\_z\_calibration: Klipper plugin for self-calibrating z-offset](https://github.com/protoloft/klipper_z_calibration) Likely, this is no longer properly installed due to the Klipper update. So, either reinstall it according to the relevant instructions or remove it. ---

Hi, thanks for your help. Put file in extras folder and it’s good. Probably opening a can of worms now I have this ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/9/7/9753c0d8463cb37310ca214732123b515ab71544.jpeg) ---

I commented that out in config and the can of worms blow open 😁 looks like the mcu software needs updating as well. ---

I decided to do a fresh install of everything being it’s been a few years. I’m doing my V0.1 first to get familiar with the process again. Klipper error is looking for Heatsoak.cfg in printer\_data/config. I’m glad I’m retired now at least I have more time. I think I remember why I haven’t touched them for a while. it would be nice to actually print something it’s a little bit frustrating. Thanks for the help so far. ---
