6. Operating Instructions

This section outlines the basic steps for operating your Genmitsu CNC machine.

6.1 Powering On/Off

• Power On: Connect the power supply to the machine and a suitable electrical outlet. Flip the main power switch to the 'ON' position.
• Power Off: Always turn off the spindle first, then the main power switch. Disconnect from the power outlet when not in use.

6.2 Software Connection (Grbl)

The 3020-PRO MAX V2 operates on open-source Grbl V1.1 firmware. You can control the machine using a computer with compatible software (e.g., Candle, UGS) or an optional offline controller.

• Computer Connection: Connect the machine to your computer via a USB cable. Install the necessary drivers and CNC control software.
• Offline Controller: If using an offline controller, ensure it is properly connected and loaded with your G-code files.

6.3 Spindle Control

The spindle speed and operation are typically controlled via G-code commands or directly through the CNC control software/offline controller.

• Speed Adjustment: Adjust spindle speed according to the material and cutting tool.
• Tool Changes: Always power off the spindle before changing cutting tools.

6.4 Using Expanded Functionality Ports

• 3 Pin Laser Port: Connect a compatible laser module to this port for laser engraving applications. Refer to the laser module's specific instructions for setup and operation.
• Air Assistance Pump Port: Connect an air assistance pump to this port to clear debris during cutting, especially useful for laser operations or certain milling tasks.
• MPG Port: Connect a Manual Pulse Generator (MPG) for precise manual control of axis movements, allowing for fine positioning and setup.

6.5 Limit Switches and Emergency Stop

• Limit Switches: The machine is equipped with limit switches to prevent axes from moving beyond their physical limits. These are crucial for machine safety and homing procedures.
• Emergency Stop: In case of any malfunction or emergency, press the red emergency stop button immediately to cut power to the motors and spindle.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your CNC machine.

• Cleaning: After each use, clean the machine to remove dust, chips, and debris. Pay special attention to the guide rails, lead screws, and spindle area. Use compressed air or a soft brush.
