Skew correction calculation and correction via software / Calistar / Califlower

[lord-carlos]

If you for whatever reasons won't / can't correct the skew on your 3D printer there is a way to do it with klipper.
But in order to do that you first need to know if and by how much it needs to be corrected.
For a while now there was an stl + spreadsheet you could buy for 5 bucks by that helped with that. Made by Vector3D

Cnc kitchen goes into the details:

The creator of the Califlower now made a new version that cost 10 USD per YEAR! Yes, subscription stl

Califlower Calibration Tool Mk2

Califlower is the 3D printer calibration STL and calculator tool that improves your print size and skew accuracy for better print results.

You could just pay for a single year, but then you would not get access to the calculator after your subscription ends.

Anyhow, I found an Open Source version:
It contains a .html that you can download to do all the calculations:

Calistar - Parametric, open source alternative to Califlower by dirtdigger | Download free STL model | Printables.com

Parametric skew and dimension correction tool written in Cadquery. | Download free 3D printable STL models

I have not tested it yet, but will do next time I get time.
Anyone tried one of these?

I went down this road a few years ago. Found some free tools to use but my printer was not out of Skew. Still great information to have and know.
