The Nichrome wire is held in the carriage with spring on either side. Power to the wire is fed via the stainless steel threaded rods which also act as vertical spacers between parallel wires.

The carriage runs on roller bearings with custom Delrin bushings which attach to the aluminum profiles. All the wires are contained in the frame itself and the design is modular.

The x-axis consists of two motors on each side, one on top and bottom to provide longitudinal stability. These are NEMA 17 and they run on belts on either side.

The Y-axis holds a Nema 23 motor with the belt running through the inner profile of the Aluminum extrusions. The wires from the control box are fed via a cable carrier.

The first machine was installed at an insulation profile making factory in Kozhikode. Some photos of the machine in the client’s factory.
