Compared with the old version

1. Add the function of X/Y/Z axis limit switches,optimized the XYZ limit port and the port connected to the device,making wiring and operation easier.After installing the limit switch, when the XYZ axis moves beyond the travel of the engraving machine, the limit switch will trigger the machine to automatically stop the movement.
2. Add the function of emergency stop button,this function can be used when an emergency stop is required at work, making our work safer and more efficient.
3. Add the power button switch and move the power switch button from the bottom to the side,simple operation,more safety in the process of using the machine.

Support two engraving methods

• The control board support two engraving methods,our package comes with a spindle motor but without the module in the picture above.

Advantages

1. Add emergency stop button port, probe port and XYZ limit port.
2. Add the outer casing: protect control board in transit,to avoid short circuit problem during use;
3. Add the power button switch;
4. Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy;
5. Add the fan port to force heat dissipation;
6. Add offline recognition,can insert offline modules and computers at the same time.Offline will automatically identify if there is computer control.
7. Enhanced spindle drive,can support 20000rpm spindle.support more powerful spindle.
8. Improved USB interface: The original USB interface is patch soldering, transport collision and improper use, easy to drop, now changed to plug-in, very strong;
9. The spindle drive increases the optocoupler isolation, which makes the control board generate less heat, and the spindle speed adjustment is more linear and safer.

Applications

• CNC 3018 Mini CNC machine small size, light weight, USB interface, GRBL control systems, great cnc router machine for beginers;3018 PRO cnc machine is very easy to install,stable structure.
• Main application:can be engraved plastic, wood, acrylic, pvc, pcb, wood and the like material.soft metal like copper and aluminum and other materials, but can not carve hard metal, jade or other very hard texture of the items.

More applications

If you change the spindle to a module,then also can carve the kraft paper, wood, leather(wallet), bamboo, rubber.

GRBL software

• Our parcel include a 4G USB flash drive,you can download the english user manual and GRBL software from the flash drive.
• File formats supported by the software: *.nc, *.ncc, *.ngc, *.tap, *.cnc.
• Software used to create Gcode: Carbide Create, Artcam, MeshCam, Fusion360, Inkscape etc.
•
