- Your config file is expected to be in `/home/mayologutierrez/printer_data/config/printer.cfg`
- Always refer to the `klippy.log` to check what config is in place. It is **the only source of truth**
- Follow some guides, step by step, e.g. [Installing Klipper with KIAUH](https://klipper.discourse.group/t/installing-klipper-with-kiauh/10734/1)
