Mercatino CNC611 - Kit entry level per cnc Da 3 a 6 motori passo passo, una meravigliosa scheda di controllo elettronica con 5 input digitali e 2 uscite a relè, cavo di collegamento al PC & more per realizzare la CNC dei tuoi sogni fino a 6 assi. Da oggi nella nuova versione 611 che ha migliorato alcune caratteristiche elettriche (buffering e amplificazione segnali della parallela a ridosso del connettore), rende disponibili nativamente fino a 6 assi ed è di assemblaggio più facile grazie al PCB doppia faccia. Il kit è disponibile in versione De Luxe oppure Chiavi in mano (+20 euro). Con questo kit ho realizzato Rumorella, la mia CNC legnosa rumorosa in grado di incidere, fresare, tagliare e forare legno, plastica, alluminio e... basette di vetronite.
Stepper motor Animation of a simplified stepper motor (unipolar)Frame 1: The top electromagnet (1) is turned on, attracting the nearest teeth of the gear-shaped iron rotor. With the teeth aligned to electromagnet 1, they will be slightly offset from right electromagnet (2).Frame 2: The top electromagnet (1) is turned off, and the right electromagnet (2) is energized, pulling the teeth into alignment with it. This results in a rotation of 3.6° in this example.Frame 3: The bottom electromagnet (3) is energized; another 3.6° rotation occurs.Frame 4: The left electromagnet (4) is energized, rotating again by 3.6°. When the top electromagnet (1) is again enabled, the rotor will have rotated by one tooth position; since there are 25 teeth, it will take 100 steps to make a full rotation in this example. A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. Fundamentals of operation A stepper motor A bipolar hybrid stepper motor
Jones on Stepping Motors Index Abstract This tutorial covers the basic principles of stepping motors and stepping motor control systems, including both the physics of steppers, the electronics of the basic control systems, and software architectures appropriate for motor control. Introduction Stepping motors can be viewed as electric motors without commutators. Typically, all windings in the motor are part of the stator, and the rotor is either a permanent magnet or, in the case of variable reluctance motors, a toothed block of some magnetically soft material. For some applications, there is a choice between using servomotors and stepping motors. In making a choice between steppers and servos, a number of issues must be considered; which of these will matter depends on the application. Stepping motors are known in German as Schrittmotoren, in French as moteurs pas à pas, and in Spanish as motor paso a paso.

arduino meets processing - PUSHBUTTON The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites. On this website we explain how to: set up electronic circuits with various kinds of sensors, control and measure the sensors with the Arduino board, send the data to the computer, and use the received values to generate computer graphics with Processing. For all examples you need some basic electronic equipment such as a breadboard, resistors, the sensors, and some wires. The following sensors are dealt with on this website: All examples contain a list of the parts as well as the Arduino and Processing files you need. The Processing files have a DisplayItems class which paints a grid with values, a black or white background. Feel free to play around and have fun exploring the wonderful world of Arduino and Processing!
