### Basic Information:

Printer Model: CR-10 Smart (modifyed)  
 MCU / Printerboard: SKR TUrbo 1.4  
 Host / SBC: Raspberry Pi 4b  
 klippy.log

### Describe your issue:

The follow documentation is wrong/incomplete:

> **[Axis Twist Compensation - Klipper documentation](https://www.klipper3d.org/Axis_Twist_Compensation.html#axis_twist_compensation-setup-and-commands)**

The first issue is the documentation don’t tell about the installation proccess. Also, I can’t find the last stable version. I used the 6149 branch to test:

`git fetch origin pull/6149/head:x-twist-compensation-simple`

After configure all params in printer.cfg, I received the error  
calibrate\_end\_y is not part of [axis\_twist\_compensation] section.

After remove it, tried again using:

`AXIS_TWIST_COMPENSATION_CALIBRATE AUTO=True`

But I just see a last update (2 weeks ago) the auto calibration was removed.

Well, not sure if I’m missing something but the documentation is too simple and incomplete and not all describet is working property.

Could someone give some help?

Hello @tiagomaricate !

What installation process?  
`[axis_twist_compensation]` is part of Klipper. There is no need for installation.

If you use a random commit from a random branch you can’t expect the official documentation to match that commit’s behaviour.

There _is_ a proposed change to remove the `auto` parameter: [axis\_twist\_compensation: remove auto parameter from axis\_twist\_compensation by yochiwarez · Pull Request #6739 · Klipper3d/klipper · GitHub](https://github.com/Klipper3d/klipper/pull/6739), but that has not been merged so the published documentation is accurate for the current state of the code. If that PR is merged, the published documentation will update shortly afterward with the changes from that PR.
