#c_lang Klipper is a special software for 3D printers that uses a computer to help the printer work better. It makes prints faster and more precise by controlling the printer's movements very accurately. This means you get better quality prints with less vibration and fewer mistakes. Klipper also helps reduce issues like nozzle oozing, which can ruin prints. It's free and easy to set up, making it a great choice for anyone looking to improve their 3D printing experience. https://github.com/Klipper3d/klipper

How #Django knows to #UPDATE vs. #INSERT when you call #save (), #Django follows this algorithm: If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.
