4. Impostazione

4.1. Stepper Driver Installation (TMC2208 UART Mode)

1. Identify Driver Slots: Locate the five stepper driver slots (X, Y, Z, E0, E1) on the MKS Gen_L 2.1 board.
2. Insert Drivers: Carefully insert the TMC2208 stepper drivers into their respective slots, ensuring correct orientation (refer to the silkscreen on the board for pin alignment).
3. Configure Jumpers: For UART mode, specific jumpers need to be set. Consult the MKS Gen_L 2.1 schematic or official documentation for the exact jumper configuration for TMC2208 in UART mode. Typically, this involves setting jumpers to enable the UART communication pins.
4. Collegare i motori: Connect your stepper motors to the corresponding X, Y, Z, E0, E1 motor output headers. Ensure correct wiring for each motor phase.

4.2. Collegamenti elettrici

• Potenza in ingresso: Connect your 12V/24V DC power supply to the main power input terminal block (H-BED +12/24V). Observe polarity.
• Letto riscaldato: Connect your heated bed to the H-BED terminals.
• Hotends: Connect your hotend heaters to the HE0 and HE1 terminals.
• Tifosi: Connect cooling fans to the FAN terminals.
• Finecorsa: Connect X, Y, Z, E0, E1 endstops to their respective signal pins. Ensure correct wiring for normally open (NO) or normally closed (NC) configurations as per your firmware settings.
• Display: Connect your LCD display (e.g., 12864 LCD) to the EXP1 and EXP2 headers.
• Termistori: Connect thermistors for the heated bed and hotends to the T0, T1, TB terminals.

4.3. Firmware Configuration and Upload

1. Download Marlin: Obtain the latest stable version of Marlin firmware from the official Marlin GitHub repository.
2. Configure Marlin: Modifica il Configuration.h E Configuration_adv.h files to match your printer's specific hardware, including:
   • Board type (e.g., BOARD_MKS_GEN_L).
   • Stepper driver type (TMC2208_STANDALONE or TMC2208_UART, depending on your jumper settings).
   • Motor steps per millimeter (steps/mm).
   • Thermistors and heated bed settings.
   • Endstop logic.
   • Enable UART communication for TMC2208 if configured.
3. Compile and Upload: Use an IDE like PlatformIO (recommended) or Arduino IDE to compile the firmware. Connect the MKS Gen_L 2.1 board to your computer via the USB cable and upload the compiled firmware.

5. Operativo

Once the MKS Gen_L 2.1 board is correctly installed and firmware is uploaded, you can begin operating your 3D printer.

• Accensione: Connect the power supply and turn on your 3D printer. The display should initialize, and the board will perform its startup sequence.
• Ritorno a casa: Use the printer's control interface (LCD or host software) to home all axes (X, Y, Z). This calibrates the printer's position.
• Controllo della temperatura: Monitor and set the hotend and heated bed temperatures. Ensure they reach and maintain the desired temperatures.
• Stampa: Carica il tuo codice G file via SD card or a connected host computer. Initiate the print job from the printer's interface.
• Monitoraggio: During printing, observe the printer's movements, temperature stability, and print quality.
