Hello how do you connect to an ender3 pro?
We don’t have specific integration instructions for the ender3 pro. However, the Discov3ry is compatible with most open source 3D printers. You would just have to figure out the proper order for the stepper motor wires (the integration kit terminates to a standard plug ready for the Ultimaker 2+). You may have to make a simple adapter plug to connect to the ender3 pro. From that point, you can have a look at our post for connecting to the Felix 3.0/3.1 to get an idea of adjusting the eeprom and slic3r settings. You will also have to make your own nozzle adapter, but this can be as simple (like a zip tie) or fancy (custom 3d printed mount) as you like.
