Proxxon MF70 Miller CNC CONVERSION. Fundamentally this has to do two things, feed the Gcode to the miller controller and allow the miller controller to be set to a known reference point. The first thing you must do is to edit the code so that it is looking for your named serial device, if you don’t do this it will default to the last device it sees in the list which is almost guaranteed to be wrong. Next attach the Arduino controller board any command sent by the software will wait for an acknowledgment string of “ok” to be returned from the miller, if you have not got a miller attached it will appear to freeze at this point as it waits forever for the string to be returned. The printout at the bottom of the processing window shows you what serial port it is attached to as well as echoing the commands sent to the hardware. Moving and aligning the miller is handled with a jog control type of display.
When you are all set up then you need to turn on the miller and hit the “Go Mill” button. Mantis 9.1 CNC Mill - Make Your Bot! The Mantis 9.1 design is a radical departure from version 8 and earlier. Most notably, the part count has been almost halved! The current design has 13 parts, all of which can be made with a handsaw and a drill press.
Also, I've traded away my alignment free exactly-constrained design for extra stiffness. Several unsuccessful attempts to eradicate the last of the slop in the Z axis on version 8 lead me back to the world of over-constrained parallel rods. My previous attempts at an over-constrained design (versions 1-5) all failed because I was unable to make the rods sufficiently parallel to avoid jamming. What to do? The solution to this problem came to me one day in the shower— stack the two wooden endplates, and then drill the rod holes through both pieces at the same time. Once we have a precise set of holes, it's easy to slip two sliding brass bushings on each of the rods and press the rods into the endplates.
Video Build Instructions David's Original Plans Australian Plans Completed. 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. The upper right board was milled at a speed approximately 50% higher than that of the Modella. This possible in part due to the Mantis MTM's increased spindle speed, about 20,000 rpm. 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.

Ce projet a pour objectif de vous permettre de réaliser une CNC de table à un prix abordable. Nous envisageons de proposer des kits qui seront assemblés lors d’un Workshop en un temps restreint (2 ou 3 soirées) avec les personnes intéressées. Les usinages complexes (axes, vis, bois découpé à la CNC) seront réalisés avant ce qui permettra de se concentrer sur le montage de la machine, les tests et la mise en route afin que la pédagogie prime sur la technique.
Nous envisageons de procéder de la façon suivante : Réétude de Mantis pour l’adapter aux fournisseurs, unités et attentes européennesRéalisation d’un prototype fonctionnel, et mise au pointDémonstrations de la machine lors de soirées DIY dans divers lieux publics (Medialabs, collectifs d’artistes, etc..), lors desquelles nous prendrons les inscriptions pour le Workshop MantisPlanification du workshop,Achats matière première et réalisation des kitsWorkshop : probablement début 4e trimestre 2012 Projet d’origine : Variante du projet : Eagle Pair® 190-540nm Standard Laser Safety Goggles.

For the Arduino I started out writing my own software. But while searching for a good way to control movement from the serial port I stumbled upon something called "Grbl ". This is a g-code interpreter with lots of nifty functions. As I already had everything connected to the Arduino I had to ether change my connections or change the software.
Luckily it is easy to change control pins in the software. I did however have to download Winavr and then the code from github.com . I have however changed the pin-out since then and here in the instructable I use the default pin-out of Grbl. Important: The current version of Grbl (0.6b) has a bug in the queue system. Any way you choose to do it you will end up with a .hex file that you must get into the Arduino. The Arduino needs to be set up for the job. Grbl 0.6b '$' to dump current settings" If you enter $ followed by return you will get a list of options.
You must change the steps/mm for X and Y axis to 53.333 on both. Buy: Table croisée Proxxon(à coordonnées) KT 70 - Outillage - Outils électriques Proxxon - METIVIER MODELISME. Cardboard Solar CNC. Test #3 above: 1 inch/minute, letters 7/16 inch tall, kerf < 0.024 inch First, this 3 axis CNC gantry system was built on a lark, out of cardboard and mostly salvaged parts. Building it kept me sane through late December - though how sane is it to build machine tools out of cardboard? It functions; which is something short of saying it works.
It's fun as a pen plotter, but not well suited to the kind of precision positioning this Solar CNC project needs. Still, it's good enough for these first trials, and getting some real use out of it is redeeming an otherwise strange and wasted December. Mounted to the z-axis is "the cutting tool", which is the real focus of this project. The familiar part of the cutting head is a lens to focus sunlight down to the smallest burning point we can achieve. I ordered a couple bare glass lenses from Anchor Optics. To get the sunlight to the lens, in a consistent downward orientation, we need the contraption above the lens. But I think it might work. Easy to Build Desk Top 3 Axis CNC Milling Machine. PCB Milling. PCB Milling Release status: Concept One obvious goal of making a RepRap replicatable is getting it to make it's own PCBs or other electronic circuitries.
PCB milling is one of the more promising ways of Automated Circuitry Making. Recent firmwares understand a pretty standard flavour of GCode, opening the door to a lot of toolpaths already existing. Researchers have already milled out functional PCBs on the WolfStrap. (Should these be moved to Useful Software Packages ?) While a gazillion of softwares for creating and manufacturing circuits and PCBs exists, it was surprisingly difficult to find a working combination. All applications described claim to run on all major OSs: Linux, Windows, Mac OS X. gEDA gEDA is a software suite with schematic and PCB layout editor. Installation on Linux You want at least gschem, pcb and xgsch2pcb. Sudo apt-get install geda geda-utils geda-xgsch2pcb The version currently coming with Debian/Ubuntu by default is pretty old. ... or install from source: gerbv . PCB CNC.

Introduction CNCs can facilitate in the creation of PCBS: Manual etching and then using CNC to drill automatically. Cutting out the board , to have round PCBs, or similar. Automated isolation routing: From a PCB some surface parts are milled away, so that the connection copper area are left isolated. Currently, all three steps are working on the Geilomat. For the isolation, there is the normal approach, where all contours of copper areas are milled. Some results are given in the soup of the Geilomat 0805 SMD resistors work fine, although the solder locations are not visible any more. Examples A normal isolated result. A voronoi milled PCB (left), a normally milled PCB, and a traditional PCB. Time Consumption For a complete, dense EuroPCB, expect about one hour of total time: For an arduino shield, expect about 30 minutes: Pros/Cons Pros: Cons: It calls a couple of external programs: Usage Hints Links.
