Feature Request - Klipper integration for automatic heating chamber functionality with Klipper printers (Snapmaker U1)

It would be nice to have full integration with Klipper printers to be able to automatically setup chamber temperature based on printing material (PLA/PETG/PC/ASA). Also, wait until the set temperature is reached before printing...

Start by mapping the repository’s current printer-control entry points and how material-specific settings are represented. Then determine how Klipper printers can receive chamber-temperature commands and report that the target temperature is reached. Done means documented support for the listed materials, automatic temperature setup, and waiting before printing.
