### Basic Information: Printer Model: Voron V2 MCU / Printerboard: Octopus [klippy.log](https://klipper.discourse.group/uploads/short-url/9yC6sU5ltZrd0krZAM1Ceqn9Xau.log) (1.9 MB) I got an "Internal error during connect: ‘PrinterProbe’ object has no attribute “sample\_count” after the last update. Followed by several other errors related to the Printer Probe if I manually fix this one. Basically, auto z config cannot access the probe anymore. I suppose this is an unwanted side effect of commit ([d4bae4d](https://github.com/Klipper3d/klipper/commit/d4bae4dffe8d3996ed1b1dd8f5230a062ae3d033)) Any recommendations on how to proceed? ---

What probe are your using? If a beacon then that team knows about it and is working on a fix. If you need a working printer now then you’ll need to roll back your klipper to commit 49c0ad6. ---

You are using an unofficial Klipper modification (z\_calibration.py) that is causing issues because the underlying **official** code-base changed. Klipper does not carter for unofficial modifications since there is no official plugin system and the APIs and methods are not guaranteed to stay stable. If you want to continue using this modification, the original author would have to adapt. ---

My problem was solved by the author of z\_calibration.py. So this thread can be closed. ---
