G-Code from a Raster Image - Open Source CNC Toolpathing Workflow
Duration: 8:36
Description: A quick and easy technique for generating G-Code for use on a CNC router. A raster image is turned into a heightmap based on the greyscale levels of each pixel. This is a great way to get 3D forms without having to make CAD models. See more tutorials at diylilcnc.org

Duration: 12:17
Description: Help us produce more tutorials by supporting our kickstarter campaign! www.kickstarter.com An overview of free & open-source toolpathing for the DIYLILCNC. Turn a raster image into a G-Code engraving pattern with GIMP, Inkscape, Pycam and EMC2 in Ubuntu.
Description: DIY CNC kits are now within easy reach of small groups looking for fun projects. In response to a request on our forum, we'll be posting a multi-part series on modeling, toolpathing, and CNC fabricating pinewood derby designs! For more info: diylilcnc.org

Description: CNC adapter PCA is for sale! 25 Euro including shipping. Documentation links of the PCA can be found at the bottom of this description. Please send me an email when you're interested: JEWACNC@gmail.com. -------------------------------------------------------------------------------- This DIY CNC system is made out of many re-used parts and pieces. The video is a timelapse of all the work done, I don't claim the rights of the music, it is just there to block some of the noise of the machine. It is controlled with DeskCNC, has 3 (modified) UHU-servo drives and a power/safety unit mounted underneath the base plate. The electronics ensure safe operation, and also provide diagnostic information in case of errors. It is (since 1998) the forth version I made, but the first one which is able to manufacture usable parts. The earlyer versions where based on stepper motors which could not really handle the bulky mechanics. As an electronic engineer, the mechanical part is usually the most difficult piece. Luckily my uncle helped me out a lot with valuable advice and many many weekends preparing the so needed mechanical parts required to mount sensors, motors etc. The accuracy for X and Y is approx 3uM per step, and for Z 0.5uM per step. Ofcource I have to add some mechanical tolerances, but it is much more than enough to make small PCB boards, front panels, toys etc. The speed is set to a low safe value, but can be increased till 375mm/sec! Even at these speeds the amplifiers and ...
