Add E-stop & XYZ Limit switches & Offline controller

• The upgraded cnc 3018 pro machine is equipped with emergency stop button and XYZ axis limit switches.
• With GRBL offline controller,support SD card and TF card at the same time, standard capacity 1G; with this offline controller, you can directly control the CNC router without connecting it to your computer.
• After inserting the file into the SD card,the engraving file can be directly identified. You can also use the micro USB cable to connect the offline hand controller board to your computer and save the file directly.
• Manually control: manually adjust X,Y,Z axis location as engraving starting point,manually open or close spindle,manully open or close cooling fan
• File engraving: after off-line controller save file, it can connect the GRBL control board and process engraving,no need to connect PC computer
• Save file: after the off-line controller connect PC,it will be recognized as USB,large capacity storage device, can access engraving file directly.

GRBL Control Board

• Input voltage: 24V DC
• Connection: PC-USB connection
• Support software: GRBL controller/Candle/UniversalGcodeSender
• Master chip: atmel 328P (arduino nano)
• Spindle drive chip: MOSFET (recommendation 24V,current : within 10)
• The spindle supports 0-100% adjustable PWM power.
• Support stepper motor: 12V, maximum current of 2A or less is recommended within 1.5A and additional heat. (Any stepper motor Nema17/Nema23)
• Power Interface: 5.5-2.5mm DC interface
• Support PWM / TTL signal control,power 0-100% adjustable.

• Add outer shell
• Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy;
• Add the fan port to force heat dissipation;
• 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;

• 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.
• 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.
• 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.

• Add emergency stop button port, probe port and XYZ limit port.
• Add the outer casing: protect control board in transit,to avoid short circuit problem during use;
• Add the power button switch;
• Add offline recognition,can insert offline modules and computers at the same time.Offline will automatically identify if there is computer control.
• Enhanced spindle drive,can support 20000rpm spindle.support more powerful spindle.
• 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.

Features

Applicable materials

• Head can be rotated left and right to adjust focus,the smaller the focus,the better the effect.
• The module comes with an aluminum casing and is also equipped with a cooling fan, ensuring the advantage of strong heat dissipation.
• Low noise, high precision, dedicated for engraving machine.
• Equipped with a 3-pin plug, plug and play, very convenient.

Advantages

• 15W power,can be carved wood, bamboo, paper, ivory, leather, flammable plastic, PCB, ceramic/stone, metal surface paint, metal surface plating etc.
• Can not work on metal, iron, glass, 201/304 stainless steel, jewelry or silver.

Applications

1. Upgraded 3018 Pro Mini CNC machine small size, light weight, USB interface, GRBL control systems, great cnc router machine for beginers;
2. Very easy to install,stable structure.
3. Main application:can be engraved plastic, wood, acrylic, pvc, pcb, wood and the like material;
4. soft metal like copper and aluminum and other materials, but can not carve hard metal, jade or other very hard texture of the items.
5. if you change the spindle to a 15W module,also can be carved wood, bamboo, paper, ivory, leather, flammable plastic, PCB, ceramic/stone, metal surface paint, metal surface plating etc.
6. Can not work on metal, iron, glass, stainless steel, jewelry or silver.

Q&A

Q: What materials can the milling cutter generally engrave or cut?

A: Wood, acrylic (acrylic), pcb, pvb, soft metal, iron, glass, stone etc.

Q: What thickness of wood or acrylic can generally be cut by module?

A: 3-5mm wood board (acrylic), speed setting 100, power setting 1000;

Multiple cuts can cut 12mm wooden boards by spindle.

Q: The X,Y and Z axis of the machine cannot be moved,what should I do?

A: First check whether the wires are correctly connected, whether the power switch of the control board is pressed, and then check whether the coupling is off.

Q: The engraved image is reversed,what should I do?

A: Enter 3=2 or RST=*command
