Are you still worried about what gifts are best suited for your friends? Do you want to choose something creative to express your sincere wishes? With the advancement of the economy, higher requirements on presents become more necessary. Gifts with innovative ideas are coming into our sights.
Some people want to print their favourite pictures or cartoon characters on some small ornaments. People who are keen about DIY wish to make pcb at home to make their own electronic works. Based on these requirements, I sprouted the idea of making a laser-engraving machine. The machine is made from discarded materials, which saves the money and put the concept of “recycling resources ” into practice as well. However, the first generation of laser-engraving machine can only satisfy the want of printing pictures. Thus, I expand the framework in my second version and propose the innovative method of circuit-board-etching in order to broaden the uses of the machine.
The machine is basically made from unwanted materials that you can easily find in second-hand markets. I use the old CD driver and printer to make this machine and it is shown later in my article.
Step 1: Demo Video
This is a demonstration of the process of carving
Step 2: (first generation) Using the CD-ROM production -- get laser and stepper motor
I took two wasted CD-drives apart because we need the steppers and lasers from them.
Step 3: (first generation) Assemble the circuits and the drive frames
This is my first-generation product, using the wasted CD drives and Arduino.
Let’s start assembling! This is the specific making process: solder the circuit board by Arduino Nano and a4988 stepper driver; use the waste wood slats and the disassembled drives’ stepping motors. Wood is not only easy for making changes, even with a saw or utility knife, but also environment-friendly. Always remember to keep the stepping motors on the x and y axes perpendicular to avoid printing crooked or skewed pictures.
Step 4: (first generation) The design and improvement of machine frame
Here is the process of designing and optimizing the machine frame, though many of my attempts failed. But these trials were to let more people make simple and interesting laser engraving machines using their discarded CD drives more conveniently and economically. I will attach a design sheet in the next section.
