The installation of other equipment (such as limit switch, laser head) should be installed according to the actual situation.ġ) Install the grblmain library file and burn programĭownload and unzip grblmain.zip, and then replace config.h in grblmain folder, the new config.h: You can reference for the following picture: As shown in picture:Īfter finished the above steps, you need to plug A4988 and Arduino NANO into CNC Shield V4.0, please ensure it’s the correct direction of A4988 and Arduino NANO, or it may burn your devices. In order to improve the precision of engraving, use 1/16 segment, it needs 3 jumper caps to cover MS0、MS1、MS2. Each segment is set by the MS0、MS1、MS2 pin header in the CNC Shield V4.0, cover the jumper cap to the pin header represents high level, do not cover the jumper cap represents low level.Įach segment is specified set as shown in the following table: MS1 We use A4988 as the motor driver, A4988 support 1 segment, 1/2 segment, 1/4 segment, 1/8 segment, 1/16 segment. The input voltage of CNC Shield V4.0 is DC 7.5V-12V, do not higher than 12V. Also, CNC Shield V4.0 also has I2C interface, you can connect LCD screen which has the I2C interface. There’re 3 slots in the board for stepper motor drive modules, can drive 3 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, it’s very convenient to use.ĬNC Shield V4.0 has some GPIO of Arduino NANO, it’s convenient for connect other modules, like limit switch. It is also selectable between 3.3Volts and 5 Volts.CNC Shield V4.0 can be used as a drive expansion board for engraving machines and need to be used with Arduino NANO. Now use female jumpers to connect the berg headers to power up other components and microcontroller units. To power peripheralsĬonnect similarly as previously explained. ![]() The left and right jumpers are two independent channels and can provide different voltages simultaneously. If you want the bread power rails of 5 volts, adjust the jumper accordingly. Adjust the jumper to the desired output voltage. If the module is energized, the LED lights up. Connect the input power supply either regulated or unregulated to the DC input jack. It should be placed in such a way that the left and right jumpers of the module coincide with the power rails of the breadboard. To power the breadboard through the BBPS module, mount it on to the breadboard. This helpful BBPS module comes in handy in a vast number of projects. This schematic diagram becomes handy when any of the components got damaged and we want to replace that component. The schematic is provided for the visual and describes the circuitry of the breadboard based power supply module.
