So when you select the power supply, please refer to the corresponding the motor driverвЂ™s data sheet.

Although the input voltage supports power supplies up to 36V, does not mean that you can use 36v under any circumstances, because some motor drivers supply voltage (VMOT) is less than 36V, such as A4988, its supply voltage is 8-35V, if you use 36V power supply, it will burn the motor driver. As shown in picture:ДЈ) The inputВ voltage of Arduino CNC Shield V3.0 is DC 12V-36V, do not input more than 36V voltage. In order to improve the precision of engraving, use 1/16 segment, it needs 3 jumper caps to cover M0, M1, M2. Each segment is set by the M0, M1, M2 pin header in the Arduino CNC Shield V3.0, cover the jumper cap to the pin header represents high level, do not cover the jumper cap represents low level. The picture shows the connection of A4988 motor drivers and Arduino CNC Shield V3.0.ДЄ4988 support 1 segment, 1/2 segment, 1/4 segment, 1/8 segment, 1/16 segment. When installing the hardware, please pay attention to the following points:ДЎ) Incorrect connection ofВ +/-В may destroyВ your devices, even cause fire.Дў) Please make sure to insert drivers in correct direction, or it may burn the mainboard and drivers, specific installation direction please integrating Arduino CNC Shield V3.0, refer to the data sheet of motor drive. Version 3.00 of the board added a jumpers to configure the 4th axis(Clone the other axisвЂ™s or run from Pin D12-13), Comms Header(RX+TX, I2C) and a Stepper Control Header(All Pins needed to run 4 steppers)Д¬onnect the components according to the actual situation, such as motors, limit switches, lasers, motor drives and so on. I2C can later be implemented by software to control things like spindle speed or heat control.

Serial Pins ( D0-1) and I2C Pins ( A4-5) have their own break out pins for future extensions. Spindle and coolant control has their own pins.Д®xternal GRBL Command Pins have been broken out allowing you to add buttons for Pause/Hold, Resume and Abort. (We do advice that an extra emergency button also be installed that cuts power to all machinery. This does the same as the RESET button on the Arduino board.

(For use with aВ normallyВ open switch)Д®Stop вЂ“ These pins can be connected to an emergency stop switch.

This makes it easier to install two limit switches for each axis. Limit switch pins have been doubled up so that each axis has a вЂњTop/+вЂќ and вЂњBottom/-вЂњ. In addition to have all the GRBL function pin, Arduino CNC Shield V3.0В also have some additional pins to achieve more features: After insert Arduino CNC Shield V3.0 into Arduino UNO, and installed GRBL firmware then you can quickly DIY a CNC engraving machine. ThereвЂ™re 4 slots in the board for stepper motor drive modules, can drive 4 stepper motors, and each step stepper motor only need two IO port, that is to say, 6 IO ports can quite well to manage three stepper motor, itвЂ™s very convenient to use. CNC Shield V3.0 can be used as drive expansion board for engraving machine, 3D printer and other devices.
