Electronic Equipment Description

A4988 Stepper Motor Driver

The A4988 is a complete micro-stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4988 driver has a total of 16 pins that connect it to the outside world. The connections are as follows:

• VDD & GND pins: are used to drive the internal logic circuitry which can range from 3V to 5.5V.

• VMOT & GND pins: are used to supply power for the motor which can be from 8V to 35V.

• MS1 & MS2 & MS3 pins: are step size (resolution) selector inputs, they are pulled LOW by internal pull-down resistors, hence if you leave them unconnected the motor will operate in full step mode. On the other hand, if you connect them then you may change the motor to one of five step resolutions shown in the table attached below:

• Step pin: input controls the microsteps of the motor. Each HIGH pulse sent to this pin drives the motor according to the number of microsteps determined by the microstep selection pins. The faster the pulse, the faster the motor will spin.

• DIR pin: input controls the spinning direction of the motor. Pulling it HIGH drives the motor clockwise and pulling it LOW drives the motor counterclockwise.

• EN pin: is an active low input. When this pin is pulled LOW the A4988 driver is enabled. By default this pin is pulled low so the driver is always enabled unless you pull it high.

• SLP pin is an active low input. Pulling this pin LOW puts the driver into sleep mode, minimizing power consumption. You can use this especially when the motor is not in use to save power.

• RST pin: is also an active low input. When this pin is pulled LOW, all STEP inputs are ignored. It also resets the driver by setting the internal translator to a predefined home state. Home state is basically the initial position from where the motor starts and it varies depending on the microstep resolution.

• 1B, 1A, 2A & 2B pins: are the output channels of the A4988 motor driver. Each output pin on the module can deliver up to 2A to the motor. The amount of current supplied to the motor, however, depends on the system’s power supply, cooling system, and current limiting setting.

Heat Sink

Even though the A4988 driver IC has a maximum current rating of 2A per coil, the chip can only supply about 1A per coil without overheating. To get more than 1A per coil, a heat sink is required.

It is placed above the stepper motor driver as follows:

Stepper Motor

An electrical device when it is supplies with current and voltage, it produces motion/velocity. It contains four pins: V+ (Power), PWM (servo control signal), and GND (Ground).

Arduino Uno

One of the most popular microcontroller that consist of 4 digital input/output pins, power jack, 6 analog inputs, reset button,16 MHz ceramic resonator, USB connection, and ICSP header. Throughout the pervious years a lot of successful projects were developed upon it.

Air Pump

Is a device that for exhausting air from a closed space or for compressing air or forcing it through other apparatus.

Bread Board

A breadboard, or protoboard, is a construction base for prototyping of electronics. A breadboard allows for easy and quick creation of temporary electronic circuits or to carry out experiments with circuit design. Breadboards enable developers to easily connect components or wires thanks to the rows and columns of internally connected spring clips underneath the perforated plastic enclosure.

Relay Module

2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. It uses a low level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts. It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to control a high-current circuit with a low-current signal.5V relay signal input voltage range, 0-5V. VCC power to the system. JD-VCC relay in the power supply. JD-VCC and VCC can be a shorted.

Electronic Connections

Motors

As an initial step, I started connecting the motors to the A4988 stepper motor drivers and testing them. After doing a research the connections was conducted as following:

Please note that the following diagram is essential to set each motor on either the y-axis or the x-axis:

To connect the stepper motor wire to the breadboard we used a ‘connector’ component as follows:

Then, we used the multimeter to make sure that all the wires are placed accurately in the connector in a way that they can pass voltage as shown below:

Testing Phase

We have learnt that we need to use only one 100 microfarad capacitor, because when two were used one of the have burnt as shown here:

After setting the power supply to 12 volts and confirm all the connections, the motors have successfully run:

The following code was used for testing the motors functionality:

void setup() {

  pinMode(12, OUTPUT);
  digitalWrite(12, LOW);  
}

void loop() {

  delay(3000);
  digitalWrite(12, HIGH);
  delay(30000)2;
  digitalWrite(12, LOW);
}

Relay & Air Pump

Testing Phase

With the help of the instructor the following dough pump was created using the laser cutter machine.

However the dough’s tube was not running smooth with this pump. Hence, we decided to buy an air pump and implemented it in the machine system. After buying it we first tested if the air pump can push the dough as shown here:

Final Results

Since everything went smooth, we decided to add a relay to control the release the dough release from the pump. Hence, the following steps was achieved:

First we cut out the plug of the air pump as shown below:

After that a new plug was cut to extract the brown live wire and blue neutral wire from it. Then, we have twisted the plug’s blue neutral wire and the pump blue neutral wire together as shown in the video below:

Note: Make sure to cover the twisted wires with tape to prevent yourself from any electrical shock.

Finally, the relay and the pump was connected to the Arduino:

The following diagram illustrate clearly the connections occurred:

! Caution !

Make sure to cover the area shown in the figure below to prevent any electrical shocks. Because, if the relay was placed on a metal surface (as table) the electrical pulses can travel through the pins placed at the buttom of the relay.

Flashing GRBL

The first version of GRBL was released in 2009 by Simen Svale Skogsrud. GRBL is free, open source software for controlling the motion of machines that move, that make things, or that make things move, and runs on wide variety of microcontrollers. GRBL is used to power thousands of different CNC routers, lathes, mills, lasers and more. It is essentially the standard for open source CNC machines.

​The grbl v1.1 files were downloaded through the official github link.

Then, the (GRBL) folder was added to Arduino IDE library through Sketch > Include Library > Add .ZIP Library:

The GRBL was after that flashed through File > Examples > grbl > grblUpload as follows:

Motor’s Step Calibration

Calibration of stepper motors involves determining the relationships between steps and distance. In order to calibrate the extruder, the following steps were accomplished:

Firstly, the Vernier Caliper was used to mark the distance from the starting point till 100mm away, as shown below:

Universal G-Code Sender is a Java based, cross platform G-Code sender, compatible with GRBL, TinyG, g2core and Smoothieware. This software was installed to control the movement of motors as follows:

Click on the “connect” button to create a connection between the Arduino and software:

Before moving the motors, we went on and used the online Stepper Motors Calculator, to find the best travel resolution for the type of motor used:

As shown in the above figure, the results were “4”. Hence, this value was set for both the y-axis and x-axis:

Then, the y-axis motor was moved by typing “G0 Y100” command in the software. Note: “f100” was used to control the feed rate:

As shown in the video below the extruder have moved 100mm and stopped after moving 77.32 with a difference of 22.68 from the expected movements:

The following pictures elaborate more on the actual distance the motor have move:

We used the actual distance to find the new steps. At first we missed use the formula and got 3.26. Therefore, when the new step rate was set (as shown in the figure below) the motors were still not calibrated correctly:

To find the precise new steps, the following calculations were made:

Again the x-axis & y-axis travel resolution were then set to 5.173 as follows:

The y-axis motor was moved 100mm as shown here:

Then, we did several movements to test the x-axis travel resolution as follows:

Note: To control the Spindle Relay in the GRBL the following command can be used: m4 = to turn on and m3 = to turn off.

Current Limit

When we added two motor, we tried to move the motors but the were lagging in their place as showing in the video below:

Therefore, the following calculations were made to determine the new current limit value:

The following video shows the technique of changing the current rate to 0.68:

Thus, this video shows that after changing the current both motors have stopped lagging:

Motors’ Feed Rate and Movements

As an initial step, the feed rate of the motors was tested using the following commands:

To increase the feed rate, as mentioned above we tried using “f100” as shown here:

However, the motors were still slow as shown here:

Therefore, we then increases both the “maximum rate” and “axis acceleration” through inserting the following commands:

Testing#1:

Testing#2:

Finally, we moved both the a-xis and y-axis at the feed rate desired:

Command Used in Universal G-Code Sender

The following commands were achieved to control and adjust the motors. It also includes all the trials to achieve our goals:

Wires Solidarity

After connecting all wires and with the movement of motors, the wires were always disconnecting. This issue would always effect the movement of motors as follows:

Therefore, we decided to solider the wires using the following solider wire:

The following video illustrate the technique achieved to solider all the wires:

Beauty Sprinkles

To enhance the machine finishing look, we decided to put all the electronics in a wood box as follows:

LaserGRBL (G-code Generator)

LaserGRBL is one of the best Windows software for image Laser Engraving. LaserGRBL is able to load any image, pictures and logo and send to your laser engrave with few click. Hence, this software was used to convert any image to a g-code that can be read by the grbl.

The following steps were made to convert any image to a g-code:

First, make sure to connect the Arduino to PC. When it is successfully connected to the PC “COM8” will be appeared in the area labeled ‘1’ shown in the figure below. Then, make sure to press the “connect” button labled ‘2’.

Then, click on file > open file > select the photo/logo to convert them to g-code as follows:

You can then select the type of filignment and press next.

Finally, after the g-code generated you can go on and upload it to the Arduino. For instance, the following video demonestrate one of our trials to convert “F” letter to g-code. As shown, the motors have moved and accomplished the desired letter as follows:

Pizza Dough Ratio

Finding the best pizza dough ratio is very critical. It plays a major role in the quality of the pizza outputted.

The term “Best Ratio” can be presented when the dough is liquid in a way that can be pushed using the ‘air pump’ and hard that cannot be released unless it is required.

Therefore, we went on and try many ratios as shown below:

Also, the following video illustrates one of the failed ratios:

After many testing trails we found that the best ratio is 85% of water compared to the flour (and any solid components).
