Method & Evidence

AimTo develop a microcontroller-based system capable of translating digital graphics into physical engravings or cuts on various materials using CNC principles.
MethodExperimental design and prototyping
ProcedureThe project involved designing and assembling a CNC drawing machine. Graphics and text were converted into G-code using Inkscape. A microcontroller was programmed to interpret the G-code and send commands to stepper motors (for X and Y axis movement) and a servo motor (for Z-axis pen control). The system was then tested for its ability to engrave or draw on different materials.
