This work shows the development of a fiber optic taper machine by applying a controlled melting temperature, which is induced by a 30W CO2 laser. The laser is made to influence the fiber, heating it and making it malleable. Then the tension axis of the device moves, having three independent axes X, Y and Z on the laser system, it is possible to mark the fiber in order of generate gratings. The device was designed entirely with low-cost materials, which are made for process optimization, such as resources. The software implemented is designed in Arduino for an IOT card that operates with HTML interface, is controlled from a website with which different variables can be handled for the operation of the taper machine, such as distance, speed and time. The device is controlled by means of Wi-Fi, through a website generating accessibility to the free operation of the engines, which can be executed over the same network. The machine has an aluminum base on which are two endless screws, connected each to a step-by-step motor that when turning in opposite directions move each one, a Fiber Holding Blocks on which the fiber is held to be stretched. The electronic circuit is located in a box attached to the motor system.
