3.2 Firmware Installation
The MKS Monster8 V2 supports Marlin 2.0.x and Klipper firmware. For optimal performance and compatibility, it is recommended to update the firmware from the official Makerbase GitHub repository. A Klipper host, such as a Raspberry Pi or MKS PI, is required for Klipper firmware.
For detailed instructions and firmware files, visit the Makerbase MKS-Monster8 GitHub page.
3.3 പവർ സപ്ലൈ കണക്ഷൻ
The motherboard is equipped with a TVS power supply anti-reverse and spike protection chip to prevent damage from incorrect power connections. If the positive and negative poles of the power supply are reversed, the motherboard will not function. Always double-check wiring before powering on.
Video 1: Demonstration of the power supply anti-reverse protection. The video shows that if the power supply is connected in reverse, the board will not power on, preventing damage. It also shows how to correctly connect the power supply.
The Monster8 V2 also provides a dedicated DC5.1V/3A power output for Raspberry Pi. This ensures a stable power supply, preventing common "Currently Throttled" errors that can occur with unstable power to the Raspberry Pi.

4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once the board is correctly installed and firmware is loaded, you can begin operating your 3D printer. The board supports U disk printing, allowing for convenient file transfer and printing.
4.1 ഡിസ്പ്ലേയും നിയന്ത്രണവും
Connect your preferred LCD or touch screen display to the EXP1/EXP2 interfaces. These displays provide a user interface for controlling printer movements, monitoring temperatures, and managing print jobs.
4.2 വിപുലമായ സവിശേഷതകൾ
Utilize the DFU mode button for firmware flashing. Configure driver power selection (5V or 3.3V) and set up TMC UART and SPI modes for advanced stepper motor control. The SENSORLESS_HOMING function can be configured using the Diag0-5 pins.
Figure 10: The board supports various driver modes including UART, SPI, and Normal STEP/DIR for flexible control.
5. Maintenance and Protection
The MKS Monster8 V2 is built with several protective features to ensure longevity and reliability.
5.1 Fuse Protection
The board includes plug-in fuses that provide overcurrent protection, safeguarding the motherboard wiring effectively.
Figure 11: Plug-in fuses are added to the motherboard for enhanced protection.
5.2 Back EMF Protection
A dedicated protection circuit is integrated to handle back electromotive force (EMF) generated by stepper motors, significantly reducing potential damage to the motor drivers. This is particularly important when the print head is manually moved or encounters resistance.
Video 2: Demonstration of back EMF protection. The video shows a Voron printer's print head being moved manually, generating back EMF, and the board's protection circuit preventing damage, allowing normal operation after power-on.
5.3 ESD സംരക്ഷണം
The motherboard's MOS drive circuit and temperature measurement circuit are protected by Schottky diodes to reduce damage from external static electricity spikes to the input/output (IO) pins.
Video 3: Anti-static test of the motherboard. The video demonstrates applying 4kV static electricity to the heating head interface and temperature measurement interface, showing the board continues to function normally due to its robust protection.
6. പ്രശ്നപരിഹാരം
6.1 Power-On Issues
If the motherboard does not power on, first check if the power supply wiring is reversed. Correcting the polarity should resolve the issue. Refer to Video 1 in the Setup section for a visual guide.
6.2 Raspberry Pi "Currently Throttled" Error
This error typically indicates an unstable or insufficient power supply to the Raspberry Pi. The MKS Monster8 V2 provides a dedicated 5.1V/3A output to prevent this. Ensure your Raspberry Pi is powered directly from this interface on the Monster8 V2 board.
6.3 PL08N Leveling Sensor Signal Pin Burnout
The PL08N leveling sensor signal interface is protected by Schottky diodes with a withstand voltage of 40V. This design ensures that the signal pin of the chip will not be burned out due to sensor issues or voltagഇ സ്പൈക്കുകൾ.
Video 4: Demonstration of PL08N leveling sensor signal pin protection. The video shows a 24V input applied to the PL08N signal pin, confirming that the board remains functional and the pin is not damaged, thanks to the integrated protection.
