### Basic Information:

Printer Model: RMS Core XY  
 MCU / Printerboard: MKS PI  
 Host / SBC Klipper 0.12  
 klippy.log

_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_  
_ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _

### Describe your issue:

All of a sudden my machine spits out a error that the probe is somehow undefined.  
I use Beacon instead of probe and set up configuration according to the reference manual.

After updating my system somehow this error came up and I’m not able yet to resolve it myself.

I suspect that maybe Klipper changed and now this section is unvalid?

Help appreciated! Thank you!

The beacon does not run a s probe, but as beacon.

```auto

This doesn’t work either.  
Renamed it despite the instructions directly from Beacon Homepage.

My configuration worked fine many month.  
This error is coming up just now after I updated Klipper.  
BTW I also pressed hard recovery button for Klipper because system said it was corrupt.  
Maybe here lies an explanation?

Solution:

Beacon repo was somehow not installed at all.  
Githubbing into it solved this one.

But also other previous installed packages where lost. Like Shaketune etc…

Strange!  
Something horrible happened. I don’t know hat happened but I think I have to start from scratch.

Everytime I solve a piece a new problem comes up. Now MCU is undefined…

Question:

What could cause my installation to become “corrupt” all of a sudden?  
It started with a problem where the heater\_bed was running out of its corridor.  
And not klippy.log was generated.

Crazy no?
