Tutorial sobre Motores Paso a Paso (Stepper motors) Los motores paso a paso son ideales para la construcción de mecanismos en donde se requieren movimientos muy precisos.

Tutorial sobre Motores Paso a Paso

La característica principal de estos motores es el hecho de poder moverlos un paso a la vez por cada pulso que se le aplique. Este paso puede variar desde 90° hasta pequeños movimientos de tan solo 1.8°, es decir, que se necesitarán 4 pasos en el primer caso (90°) y 200 para el segundo caso (1.8°), para completar un giro completo de 360°. Estos motores poseen la habilidad de poder quedar enclavados en una posición o bien totalmente libres.

Si una o más de sus bobinas está energizada, el motor estará enclavado en la posición correspondiente y por el contrario quedará completamente libre si no circula corriente por ninguna de sus bobinas. En este capítulo trataremos solamente los motores P-P del tipo de imán permanente, ya que estos son los mas usados en robótica. Imagen del rotor. FurnLab open source CNC. Kickstarter campaign to make production local again According to Jeffrey Matthias, founder of FurnLab, precision manufacturing is something we should all have access to.

FurnLab open source CNC

As a part of their recently launched KickStarter campaign, the FurnLab team are unveiling plans to release a unique production-ready open source CNC machine. This device will complement the existing range of DIY CNC offerings, while taking manufacturing capabilities to the next level in terms of both scale and speed. Check out this early incarnation (version 2) of the FurnLab design: Jeffrey tells how the journey began when they discovered the prohibitive costs involved in setting up a DIY device with a full-size cutting area.

I also want to reduce dependence on doodads that are made in one land only to be shipped way over to another land. So how big is this thing going to be? RepRapWiki. Edit is restricted to the sysop group (set from the "protect" tab)move is restricted to the sysop group (set from the "protect" tab) RepRap is humanity's first general-purpose self-replicating manufacturing machine.

RepRapWiki

RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...

RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. Make Your Own DIY CNC. This instructable outlines the assembly process of my 2nd generation CNC machine which I designed to be simple to build and quiet enough to be apartment friendly.

Make Your Own DIY CNC

I have included example projects that I have made in the first two weeks of using the machine to demonstrate its capabilities. This is the second CNC machine that I have designed and built. My first machine was based off of oomlout’s instructable “How to make a Three Axis CNC Machine (Cheaply and Easily)” (by far my favorite instructable and the one that got me hooked on the site).

It was moderately successful, cutting a number of parts from foam (a summary of parts made can be found on my abandoned blog here along with some build photos). The lack of overall stiffness and play in the linear mechanisms meant that plywood and plastics could not be cut effectively. 1) All of the drive mechanics are exposed. 2) The design has a low number of fabricated components and allows for low build tolerances. 3) Low operational noise. Txapu-CNC: Software. Actualmente existen varios métodos de control de sistemas libres CNC: Es un sistema linux específico para CNC, de tiempo real y preparado para controlar motores paso a paso por el puerto serie.

Txapu-CNC: Software

Disponible como CD-Live. Dispone del sistema de visualización y control. Es el ordenador el que realiza todas las tareas de control de los motores, y conectando en el puerto paralelo unos drivers de potencia podremos controlar los motores paso a paso. Es un sistema técnicamente muy bueno, pero está pensado para tener un PC dedicado al control de la fresadora (si actualizas linux puede dejar de funcionar) , y además controla directamente los motores paso a paso a través del puerto paralelo, puerto que se va quedando obsoleto hoy en día. Es un sistema de impresión 3D preparado para funcionar en Windows, Linux y Mac, ya que está realizado en Java. Este sistema tambien permite utilizar ReplicatorG para enviar datos al microprocesador. 2.3 Contraptor CNC 2.4 TxapuCNC Los componentes necesarios son:
