All the sketches so far have made use of the Arduino library calls to read and write to the Arduino pins. ... // control pin for servo motor int minPulse = 500; // minimum servo position int maxPulse ...

That’s where the servo motor comes in. ... You can drive them directly from an Arduino or similar microcontroller using a library that converts an angle into a PWM signal on one of the output pins.

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 VDC, 38 VDC (E-type).
