    We’ve seen a number of homemade CNC machines throughout the years, but Tuenhidiy’s build — made from some discarded materials — is no less impressive. This unique CNC plotter features a frame cleverly constructed out of two wooden wine boxes, which appear to be the perfect size with space for an Y-axis bed and an upright structure that actuates X movements. For the Z component, a pen is lifted using parts from a recycled CD player drive.

    Electronics-wise, the project is also quite interesting as it employs servos rather than steppers for its X and Y axes. Actuation is handled by an Arduino Uno with pre-installed GRBL firmware and a CNC shield, which sends commands to an Arduino Mega running custom firmware. The Mega — plus a custom adapter board and an L293D shield — takes care of PID control for the motors.

    More details on the machine can be found in Tuenhidiy’s write-up, and you can see it demonstrated in the video below.

    Arduino boards running GRBL software have long been used for CNC machine control, but usually you need to choose between having a router or laser cutter. This project, however, is specifically designed to accommodate both with a modular carriage system.

    Build-wise, it’s a fairly standard XYZ gantry CNC — with a frame made out of V-slot aluminum extrusions from OpenBuilds cut to length by a circular saw. The X and Y axes are controlled via NEMA 17 stepper motor and belt drive assemblies, while height adjustment is accomplished with a NEMA 23 motor and screw drive.

    The electronics are all hidden away in a separate enclosure, including the Arduino Uno/CNC shield that serves as the brains of the operation and a cooling fan to keep the temperature inside in check. 

    If you’ve been considering doing this type of build, this looks like a great place to start, and you can see a demos of it in laser and spindle modes in the videos below.
