5. Instruccions de funcionament
The Genmitsu 3018-PRO can be operated via a computer connection or using the included offline controller.
5.1 Offline Controller Operation
The offline controller allows for manual adjustment of the X, Y, and Z axes and direct execution of G-code files without a computer connection.
- Encès: Ensure all connections are secure, then switch on the power.
- Carrega File: Insert a micro SD card (not included) with your G-code files into the offline controller. Use the controller's interface to select and load the desired file.
- Control manual: Use the directional buttons on the offline controller to move the X, Y, and Z axes. This is useful for setting the workpiece origin (zero point).
- Inicia la feina: Once the workpiece is secured and the origin is set, initiate the carving process from the offline controller.
5.2 Computer Control (GRBL Software)
For advanced control and real-time monitoring, connect the CNC machine to a computer running compatible GRBL control software (e.g., Candle, UGS).
- Instal·lació de programari: Install a GRBL-compatible CNC control software on your computer.
- Connectar: Connecteu la màquina CNC a l'ordinador mitjançant el cable USB.
- Selecció de ports: In the software, select the correct COM port for the CNC machine.
- Carrega el codi G: Carrega el teu codi G file al programari.
- Set Origin: Manually or via software commands, set the X, Y, Z origin for your workpiece.
- Inicia la feina: Initiate the carving process from the software interface.
5.3 Material Compatibility and Tooling
The Genmitsu 3018-PRO is versatile and can work with various materials. Always select the appropriate milling bit and adjust cutting parameters (feed rate, depth of cut, spindle speed) based on the material.
- Materials suaus: Plastics, Acrylics, PVC, Woods (soft and hard).
- PCB: Per a la creació de prototips de plaques de circuits.
