Wiki-Mozilla Firefox RepRap is humanity's first general-purpose self-replicating manufacturing machine. 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. RepRap was voted the most significant 3D-printed object in 2017.

Online | Arduino Meditation strikes a special chord with me as a maker because it is said to foster creativity, intuition, imagination, and fantasy. I can't think of traits better suited to making. I've tried meditation in the past, but it didn't seem to stick. When I saw that NeuroSky's Mindwave headsets had dropped to $100, I couldn't resist trying meditation again, this time with feedback. These headsets measure electrical signals from your brain and determine two main metrics: attention and meditation. My Brainwave-Controlled Zen Garden is similar to a standard desktop zen garden in that you rake sand to calm yourself. If you are at peace, though, relaxed and meditative, the rake slowly draws neat spirals. To keep from messing up the sand while focusing on operating the still camera, I had to meditate, quickly switch off the garden, then take the picture. The garden is spun at a constant rate when turned on. You can find the code for the Arduino on GitHub. See the entire series here.
G-code This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The main target is additive fabrication using FFF/FDM processes. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications, too. There are a few different ways to prepare GCode for a printer. As many different firmwares exist and their developers tend to implement new features without discussing strategies or looking what others did before them, a lot of different sub-flavours for the 3D-Printer specific codes developed over the years. Introduction A typical piece of GCode as sent to a RepRap machine might look like this: The meaning of all those symbols and numbers (and more) is explained below. To find out which specific gcode/s are implemented in any given firmware, there are little tables attached to the command descriptions, like this one: Here means: yes Fully supported. experimental automatic no
Besoin de conseils pour fraiseuse CNC-Mozilla Firefox Merci Teiva pour ces infos, Je pense faire le projet que j'ai posté au dessus finallement.Il utilise également l'arduino Gcode interpreter pour l'application sur pc.Mais pour les drivers ce sont des L293d comme le schémas du dessus. Je viens de commander 5 L293D de marque Thomson et je viens d'ailleurs peut-être de faire une erreur car les Thomson ne supportent que peu de courant...apparemment ceux de Texas Instruments, eux supportent plus... Sachant que j'ai ces moteurs : unipolar 1A bipolar Voici ce qui est noté dans la datasheet des thomson:600mA OUTPUT CURRENT CAPABILITY PER CHANNEL1.2A PEAK OUTPUT CURRENT (non repetitive) PER CHANNEL et dans celle de Texas Instruments:Output Current 1 A Per Channel (600 mA for L293D)Peak Output Current 2 A Per Channel (1.2 A for L293D) Merci
HomePage What Arduino can do Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g. Flash, Processing, MaxMSP). The boards can be built by hand or purchased preassembled; the software can be downloaded for free. Arduino received an Honorary Mention in the Digital Communities section of the 2006 Ars Electronica Prix. Buy an Arduino Board Buy an Arduino Board from the official Arduino store or from one of the authorized Arduino distributors world wide. Download the Arduino Software The Arduino Software is free, open source, and available for Windows, Mac OS, and Linux. Getting Started Pictures Support Call for Maker Faire Rome 2014
GRBL Grbl is software for controlling the motion of machines that make things. If the maker movement was an industry, Grbl would be the industry standard. Most MakerBots and open source 3D printers have Grbl in their hearts. It has been adapted for use in hundreds of projects including laser cutters, automatic hand writers, hole drillers, graffiti painters and oddball drawing machines. When we ordered our first computer controlled mill in 2007 we were stumped as to how we would control it. Choosing a controller We decided on the Arduino for several reasons. Yet it is a terrifyingly puny machine in the face of this task. What Grbl has to do in 2kb: Parse G-Code, a cryptic computer language hailing from the 50s used to describe the idealised actions of milling machines. Making it all fit Getting the Arduino to do this in a robust and timely manner felt exactly like threading your run of the mill camel through the eye of a needle.

Test the Pachube library running on Arduino Coding and the API For code and programming questions, pose them to the Xively community on Stack Overflow. Many of our engineers actively participate in responding to questions there, alongside topic experts in various programming languages and hardware platforms under the 'Xively' tag. It's a great place to troubleshoot code you’ve been working on, and look for related questions. For technical questions that don't contain code and aren't answered by the API Docs, check the FAQs under 'Using Xively'. Closed Loop Control For 3D Printers One of the bigger problems with any CNC machine or 3D printer is the issue of missed steps when moving the toolhead. If a stepper motor misses a step, the entire layer of the print – and every layer thereafter – will be off by just a tiny bit. Miss a few more steps, and that print will eventually make its way into the garbage. [Misan] has the solution to this: closed loop control of DC motors for a 3D printer. Most printer firmwares use an open loop control system for moving their motors around. [Misan]’s solution to this was a DC motor coupled to an optical encoder. The entire build is heavily derived from ServoStrap, but [Misan] has a very cool demo of his hardware: during a print, he can force the X and Y axes to either side, and the Arduino in each motor will move the print head back to where it needs to be.
start – Open Desktop CNC mill Le projet ODCNC est une aide à la conception de fraiseuse numérique pour les particuliers. Un ensemble de documentations et de résultats d'expérimentations, ainsi que des plans seront publiés sur ce site. Comme le nom du projet le laisse à penser, nous allons nous concentrer sur la fabrication de fraiseuses “de bureau” facilement transportables et utilisables avec peu d'espace. ODCNC est entièrement libre, l'ensemble du contenu est placé sous licence créative commons. Certaines parties du matériel ne sont pas libres comme la carte HobbyCNC, il y a des équivalents opensource comme les cartes du projet RepRap. Si vous souhaitez participer vous pouvez me demander un compte pour modifier le Wiki (pierre_AT_equinoxefr.org) Les articles de mon Blog traitant du sujet sont ici Fraiseuse ODCNC (EquinoxeFR) en cours de réalisation
