    CNC hot wire cutter moves with four axes

    When working with Styrofoam, a conventional CNC machine like a router or laser cutter just won’t do. However, as shown in Michael Rechtin’s excellent video below, a hot wire can carve foam like butter, creating custom wings for RC aircraft or whatever else you can dream up.

    Rechtin’s build uses a double gantry system to pull the wire in a horizontal and vertical directions. As each is mechanically independent of the other, they can move in tandem, or in a skewed orientation for cutting across both the horizontal and vertical planes.

    Control is via an Arduino Mega running Grbl, with a RAMPS 1.4 shield.

    You may have a 3D printer or other “digital” tools like a laser engraver or CNC router, but what if you want to work with Styrofoam? As How To Mechatronics demonstrates in his latest project, many of the same techniques used there can be implemented to make your own Arduino-powered hot wire cutter.

    This build is constructed with 20x20mm aluminum extrusion and 3D-printed parts, and uses an Uno board and CNC shield to drive three stepper motors. Two of these motors manipulate the wire in the horizontal and vertical directions, while the third controls a turntable that rotates the foam as needed.

    As seen in the video below, it’s a brilliant design. Written instructions can be found in How To Mechatronics’ blog post, which walks you through the entire process from assembling the machine and connecting its components to preparing shapes and generate the G-code.
