Steps
Step 1: DVD driver stepping mechanism
For this project, we need two DVD burner mechanisms. One for the X-axis and the other for the Y axis. You can find the DVD burner from a corrupted CPU or your local hardware store. You can also buy a local hardware store to buy very cheap prices. Removal DVD Recorder Steps:
Use the Philips head screwdriver to remove all screws.
Unplug all connectors and cables from the DVD drive
Turn on the disk bracket and loosen the sliding mechanism.
Slide the slide mechanism.
Stepping motor is a 4-pin bipolar stepper motor.
Step 2: Find the stepper motor
Stepping motor is a 4-pin bipolar stepper motor. It is an electromechanical device that converts a series of electrical pulses into discrete angular displacements, which means it can advance a series of steps based on its control input. The behavior of the stepper motor is the same as the digital-to-ate (D / A) converter, and can be driven by the pulse of the logic system. Its main application includes variable frequency motor, brushless DC motor
Step 3: Stepper motor wiring
Using the continuity pattern of the multimeter, determine the two coils, coils A and coil B.
I have made two pairs of wires by color, one pair for coil A, second pair for coil B.
Step 4: X-axis and Y axis coordinate connection
Use glue to connect the slider of the X and Y axis to each other. And add a cut wood piece above it as a work bed.
Step 5: Assemble the laser bracket
Step 6: Laser assembly
I am using a 200-250MW 650nm laser module, which has a focus on which is used to adjust the laser point. The required heat sink must be connected to achieve longer performance. You can purchase a new heat sink from the Internet, or use the old motherboard heat sink like I use strong glue to connect the heat sink to the X-axis, connect the laser to the bracket.
Step 7: Motor assembly fixation
Connect the motor and laser line to the CNC shield
Step 8: Download and install the Benbox laser engraving machine 3.7.99
1. Download and decompress Benbox
2. Select Benbox and run the installation wizard
3. Download and install Arduino IDE. https://www.Arduino.cc/en/main/software
4. Click and install the CH340 driver.
5. Restart your computer
6. Connect the USB cable between the computer and the engraving machine.
Step 9: Install Arduino nano firmware
To install the firmware, click the lightning symbol (the rightmost icon) on top of the menu.
1. Select the appropriate COM port.
2. Select NANO (328P).
3. Select and install the LX.HEX firmware.
4. Click Install. After successfully installing the firmware, you will see a green pair next to the top update firmware title.
Step 10: Set the Benbox laser engraver parameter
The final step is to set the parameters of the engraving machine.
1. Click the blue menu icon in the upper right corner of the software.
2. Click the right arrow below the menu icon to access the parameter list.
3. As shown in the figure, enter the parameter value.
Step 11: Make the first carving
This starting point will be correlated with a red arc at (0,0) position (see the image). Draw a simple image using the drawing tool on the left. Press the green start button to start printing. Click the round-shaped laser button with adjustment until the beam is clear.
Finally: Congratulations to your successful production of the first engraving machine
