Naturally, an Arduino ... gear diameter and number of teeth. The stepper rotates the correct number of degrees and another stepper lowers the cutting head which is spinning with a common DC motor.

The build relies on an Arduino Uno as the brains. It’s equipped with an L293D motor driver shield to run two DC gear motors which drive the walking assemblies. Power is courtesy of a 3-cell ...

An interesting Arduino project has been published ... My CNC is built from 2 DC servo motors for X, Y axis and 1 stepper motor for Z axis.” Watch this video on YouTube. “Motor voltage: 24 ...
