Joining A Dog Bone Joint is a friction fit joint used to join two pieces of sheet material. Typically, dog-bone joints are made using a CNC machine. They are called dog-bone joints because the corners are rounded out and resemble a cartoon-like bone. The reason for the rounded out corners is to remove the extra material that is left by a round bit at the corners.When designing a dog-bone joint, it is important to test tolerances with scrap material. The scrap material should be the same type of material, preferably the same exact material that will be used for the final product. This is because different materials and even similar materials from different batches can produce different results.

Desktop CNC Mill Kit - Shapeoko 2 Product Details IMPORTANT NOTE REGARDING SHIPPING: Mechanical Kits have a 1 week lead time, Full Kits have an estimated lead time of 4-5 weeks Shapeoko 2 is a simple, low cost, open source CNC milling machine kit that can be built over a weekend. Assembly is required before you can use it. Pronterface - Smoothie Project Pronterface Pronterface is a host software for Reprap electronics, originally developped by Kliment. It is mostly oriented towards 3D printing, but can also be used to control laser cutters and CNC routers. Pronterface's website is at

LinuxCNC (EMC2) Instructions Once you download the .iso, this file will need to be burned to a CD or DVD. If a CD is used, the CD must have 700 MB capacity. Neat CNC Router-Made Standing Desk Requires No Fasteners - CNCCookbook CNCCookbook Before there was metal, there was wood, at least in my shop. I didn’t get into CNC at that point in my life, many years ago, but I was way into custom cabinetry. I always admired the Japanese designs that required no fasteners–everything was held together through a cunning combination of tension and pegs. Someday I hope to get a CNC Router table going in the shop and return, at least a little bit, to doing some projects in wood.

Arduino CNC Shield – 100% GRBL Compatable Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth. Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable.

Bandsaw vs CNC People keep suggesting that I should get into CNC. But I have always taken the position that CNC wouldn't save me any time for what I do. In fact, I was pretty sure I could cut out a gear faster on the bandsaw than most CNC hobby machines could. My friend Michael Grant already has a CNC machine, so I figured this would be an easy opportunity to put this to the test. So we picked some gear parameters that would be reasonably doable for both the bandsaw and the CNC machine.

KCam, EMC2, Mach3, TurboCNC,and other CNC related software links. The fall-out of the DOT-COM bust has brought CNC to the hobbyist. Couple the availability of low/no cost CNC control software, low-cost integrated circuitry, and the tons of high-end hardware now found on eBay: and for the first time in history, CNC is attainable to the hobby market. We prefer EMC2 on Linux and Ubuntu, but there are others available for those who are shy. KCAM works great in Windows 98.
