Z rotation Indicator UFO 8mm

thingiverse

You're looking to add a UFO-style rotation indicator to your Ender 3 3D printer. This can be a fun and useful modification that provides visual feedback on the print's orientation as it moves around the build plate. To get started, you'll need some basic electronics knowledge and access to a few simple components. Here's what you'll need: * A small LCD display or an LED strip * An Arduino board (or similar microcontroller) * Some wires and connectors * A power source First, you'll want to connect the Arduino board to the printer's control system using the provided cables. This will allow the Arduino to receive commands from the printer's mainboard and display them on the LCD or LED strip. Next, you'll need to write some code to interface with the printer's API (application programming interface) and retrieve the necessary information about the print job. This can be done using a library such as OctoPrint or RepRap Firmware. Once you have the data, you can use it to drive the LCD or LED strip to display the rotation indicator in real-time. You may want to add some visual effects or animations to make the display more engaging and user-friendly. As with any modification, be sure to test your code thoroughly before installing it on your Ender 3. This will ensure that everything works as expected and that you don't encounter any issues during printing.
