Building a laser cutter using Arduino is a cost-effective and customizable way to create a DIY fabrication tool. Below is an overview of the process to create your own laser cutter.
Step 1: Assemble the X-Axis
Use a sturdy base (e.g., cardboard or acrylic) and mount two parallel rods for the X-axis using shaft supports.
Attach SC8UU bearings to the rods for smooth movement.
Mount stepper motors on opposite ends of one rod to drive the X-axis.
Step 2: Assemble the Y-Axis
Create mounts for Y-axis rods using laser-cut acrylic or similar material.
Insert bearings into the Y-axis rods and attach them to the X-axis assembly.
Ensure proper alignment for smooth operation.
Step 3: Mount the Laser and Driver
Use a laser module without an inbuilt driver for better control over intensity.
Connect the laser to a linear laser driver (e.g., FlexMod P3) and calibrate it using a multimeter.
Mount the laser securely on the Y-axis and add a cooling fan to prevent overheating.
