Anycubic I3 Mega Project "Diamond Hotend" - "Tutorial"

thingiverse

It appears you've documented the process of upgrading an Anycubic 3D printer with a new RUMBA PLUS board, adding a third extruder, and configuring Marlin firmware. To clarify, here are the steps: 1. **Wiring Upgrade**: * Drill holes on the X-base plate for the Diamond Hotend. * Remove the Extruder Stepper Motor and cables from the printer base. * Disconnect the Y Axis Cable and Y Endstop Cable. * Label the wires to identify their connections. 2. **RUMBA PLUS Board Installation**: * Locate the connectors for the Heatbed, PowerSupply, and Heatbed Thermistor on the Trigorilla board. * Connect these to the RUMBA PLUS board using the schematic as a reference. * Install the stepper drivers according to the schematic. 3. **FAN Configuration**: * The RUMBA has only two FAN connectors (FAN0 and FAN1), but the Anycubic uses three fans by default. * To solve this, use the HE2 connector for connecting the chassis FAN or the permanent 12V Power output. 4. **Wiring of Additional E1 and E2 and E3 Extruder Cables**: * Connect the USB cable to the Board and use a USB extension cable if needed. * Ensure all cables are securely connected, including Endstops. 5. **Marlin Firmware Configuration**: * Use version 1.1.9 of Marlin firmware for the project. * Utilize the configuration from [David Ramiro's repository](https://github.com/davidramiro/Marlin-AI3M) and customize it to fit three extruders. It seems like there might be some missing parts or instructions in the documentation, such as adding more photos or providing a final configuration for the firmware.
