F-Engrave is a text to g-code program that is written in python and is based on the text engraving software (engrave-11) available in the LinuxCNCKnowledgeBase . The name F-Engrave is simply the predecessor programs name "engrave" with an "F" slapped on to indicate that the program can perform more formating functions like justification (left, right and center) and text on a circle. When I first released the program I had no idea I was going to add v-carving or DXF features so the name does not reflect any of those features. F-Engrave is a free open source program released under the GNU General Public License (GPL) Version 3. There is not much left of the original engrave-11 script but I needed a jumping off point. One of the things that remained intact for the most part is the CXF font reading.
From a Challenge, the Project is Born When LVL1 was discussing the purchase of a Laser Cutter, one of its members said "I could build one before you get around to buying one." And so the race began.
The plans and Solidworks files are available for free @ Thingiverse! Original Aluminium upgrades The CAD planning took about 30 hours.
This project is so far one of my favorites, one uni holidays I decided that it would be handy to have a cnc machine, so I did the logical thing and started to design one. I quickly got distracted and gave up designing and just started building the thing and this is what I ended up with. There are quite a few things I will change when I get the chance to build mk2, as I go through my build here I will do some of the rudimentary analysis that I should have done before constructing the machine, at the end of each section I will try and include some suggestions on how to make it better. Unfortunately I did not take many photos along the way so I have whipped up some basic CAD models to help me describe parts of the machine (another thing I should have done before building it).
The frame needs to be a flat base that you can mount everything on horizontally and a goose neck of some kind to hold the Z axis (the up and down part with the motor tool)firmly in place. I used one inch pipe just for fun but as it turned out it was pretty handy too. When I needed to make adjustments I could just tap it with a hammer. As you can see the post that holds the Z axis doesn't have to be in the center. It just needs to be firm and the water pipe does a good job of that.
The working area of the machine is X=450mm (approx. 17.5 inch) and Y=250mm (approx. 10 inch) and can mill parts as high as Z=110mm (approx 5 inch). The maximum milling speed on X an Y axis is 2400mm/min. and on Z axis is 1800mm/min. The resolution of each axis is 1/50 or two hundredths of an mm and one axis revolution means 4 mm of movement.
I have been trying to get my hands on a laser cutter for some time but they always seem out of reach. All the great things that can be done with a real laser cutter tickle the imagination. I feel it's time to share my latest project - a low cost laser engraver,.
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.
I crave a CNC mill for trace-isolation milling prototype PC boards and I haven’t managed to get my CupCake filament deposition machine calibrated so I can use it. (Build platform leveling and filament feed are my current showstoppers. I’ll get back to it.) I knew that someone had proposed mounting a Dremel in place of the CupCake’s extruder and that MaskedRetriever had modeled a mounting bracket ; but curiously, I haven’t heard any more about using the CupCake for milling.

Our new project contributor, Riley Porter, has a project that he’s just shared with us. It’s an Arduino Shield that plugs into an Arduino and turns it into a 3-axis CNC controller. This is very exciting hardware. For $70, you can turn your Arduino into a three-motor motion control system.
The goal of this project is to design and build a CNC wood router/engraver .This turned out to be a much larger project than I had anticipated. Bigger both in terms of dollars and hours I spent on it. It took me about 50 hours to build the mechanical portion of my CNC machine and I still have to do the electrical and software work. This posting will focus on the parts list and the mechanical systems.

La Super Spartia de bureau Désormais, plus d’excuse pour les modélistes en appartement! Voici un dossier détaillé pour se construire une CNC compacte qui se porte à la main toute montée et tient dans le coffre de la voiture! AJOUT DU 18/8/2009 : La table a été réalisée avec des moteurs 55SI de 48 pas/tours. Je ne suis pas trop satisfait des miens et je vous incite vivement à faire les modifications nécessaires pour utiliser des 96 ou 100 pas/tours. Pour trouver les moteurs, voir le site de Pierre Dradin http://www.decoupecnc.be ou poser une question sur le groupe de discussion decoupecnc sur http://fr.groups.yahoo.com/group/decoupecnc/
