Valkyrie: $100 Arduino based CNC Apparently this CNC machine can be made in about 30 hours for approximately $100. It’s powered by an Arduino which interprets the code sent to it via Python. The Arduino then sends the data to the custom motor controllers that are based on the ATtiny 2313 and l298. This is the second version of a homemade CNC machine build using mostly off the shelve parts. The first one aka “The beast” had a lot of precision issues due to play in most parts which in turn was caused by mostly bad cutting. Also one of the biggest problems was that when I have build it I did not think to allow later adjustments to be done.

How to Make a Three Axis CNC Machine (Cheaply and Easily) A salute to those who have laboured through to this point (and to demonstrate that it is reproducable) Here are some pictures of other peoples machines. Photo 1 - Chris and his friend put together this unit; laser cutting the parts out of half inch acrylic. Not only does it look super it must weigh a ton. Photo 2 - Sam McCaskill has finished his desktop CNC machine and it's looking really really nice. Photo 3 - Angry Monk's - With MDF pieces cut on a laser cutter and drive converted from toothed belts to threaded rod Photo 4 - Bret Golab's - Bret has completed his and gone through the extra step of getting it setup to work with Linux CNC (a task I attempted and was foiled by complexity). (If you have built one and would like it featured here, please send me a PM and we can arrange for the sending of photos)
MAS 863 - David Carr My final project is a 3-axis CNC milling machine that costs less than $100 (currently $87) to build. It can mill PCBs, wood, and even mild steel. These PCBs were milled using the machine. The traces are 10-15 mils. The left and lower right boards were milled at approximately the same speed as the Modela. Some more test pieces: MDO and mild steel with a 1/32 inch mill on the left, wax with a 1/8 mill on the right. Design My design was heavily influnced by Johnathan Ward's MTM-AZ, although it shares no common parts with his machine. Machine drawings (DXF) Bill of materials Brute force stepper driver The brute force stepper driver is a simple 3 axis stepper driver for use with EMC2. Here are the files for milling the board: Bottom (PNG) Holes (PNG) Mill the first/bottom layer with a 1/64 inch mill first.

MOTORES PASO A PASO - FUNCIONAMIENTO Y CONTROL POR COMPUTADORA Veamos cómo podemos realizar determinadas rutinas para el movimiento del motor desde la PC utilizando la interfaz sugerida: Haciéndolo girar en ambos sentidos: El mostrado en la figura 13 es un programa realizado en Qbasic y muy fácil de interpretar, en donde podemos ver como se puede hacer rotar el motor una vuelta en un sentido y luego otra en el sentido contrario. Puede visualizar o bajar directamente el ejecutable, llamado stepper. exe directamente desde la página de TodoRobot. Agregando dos botones para controlar el giro: en el programa de la figura 14 se ha sofisticado aún más el uso de la interfaz mediante el agregado de dos botones en el puerto de entrada TTL para indicar cuando girar hacia un lado o hacia el otro, o bien permanecer inmóvil hasta tanto no se presione ningún botón. En la figura 15 se puede apreciar el conexionado de los botones y el motor con la interfaz. El funcionamiento es muy simple.
New Arduino Mega CNC machine......(UPDATED) My new machine, the other one was a prototype, now this one will use all the electronics.... Made with MDF, bigger than the prototype...... Almost done... My new control box, X, Y, Z axis, DB9 conector for the limit switches, and usb conection to computer. Better cable arrangement..... How to make a mini milling machine- manual or CNC! I think one of the best things about tools is that they can be used to make more tools! I decided to build a miniature milling machine for machining plastic parts, creating wax patterns and for drilling really small precise holes. I also wanted to design it so that I could convert it to CNC for machining circuit boards and for doing repetitive work. The finished mill has a 11" x 18" footprint and is about 19" tall. The X axis travel is 6 1/8" The Y axis travel is 6 1/4" The Z axis travel is 2 1/4" If there are any questions about any of the drawings or something just doesn't make sense just ask! Follow along and build one for yourself!

Crea tu Mini Maquina de CNC con Arduino, Easy Driver y Ubuntu (Basada en Contraptor) Esta entrada esta dedicada a mis queridos compañeros de FIME En muchas otras Universidades le llaman tambien Robot Cartesiano, o demas nombres. Primero, si desean saber que es una maquina de CNC, o especificamente lo que haremos aqui es una fresadora de CNC, aqui explico un poco: La idea principal de este proyecto, es facilitar al lector la construccion de una sencilla pero poderosa fresadora de CNC de licencia GPL, por tanto Open Source, debido a que se necesitan bastantes conocimientos previos de muchas ramas para asi poder llegar a una conclusion final de como en realidad se puede crear esta maquina, aqui facilito toda la informacion necesaria para llevarla a cabo, y te ahorro mas o menos 15 horas de investigaciones y pruebas ya que usaremos Circuitos que son mas faciles de conseguir si no estas en EUA. Puntos IMPORTANTES: 1. 2. 3. 4. En esta INTRODUCCION nos ocuparemos de tener las piezas electronicas que necesitamos, así como Ubuntu en nuestra maquina.
LuxRender - home Arduino Controlled CNC / 3D Printer Hybrid Repetier or Marlin Firmware for Arduino Mega implement G2 an G3 circular interpolation so they are good to use for CNC and 3D Printing. However they have limitations regarding pure CNC instructions such as pecking an other GCode's.

howie m » Amateur CNC mill show and tell Friday, November 19, 2010 Amateur CNC mill show and tell Thought I’d have a go at something a bit mechanical for a change. I bought a cheapy pillar drill from Screwfix a while back - around £50 if I remember right. Mmm… precision drilling… mmm… OK, back to me: CNC mills are all the rage at the moment - loads of people seem to be building them, from huge ones through to tiny little ones you can knock up for very little money. I’ve got loads of electronic junk in boxes, so I had a dig around. It’s a scanner - a disco/nightclub light that can change colour and, using a motorised mirror, shine the beam around the room in carefully choreographed patterns. These things are the heart of a CNC machine - you can control precisely how much its shaft rotates, unlike a normal motor that spins freely when you give it power. I managed to scavenge a load of bearings and rods from old printers. I bought a few lengths of leadscrew from Marchant Dice (yay! Drill a hole in it: First: X-axis stuff Y-Axis stuff
