This is a stock motor that has a 5mm diameter shaft. It's also great for all kinds of mechanical projects, robotics, and projects. It's fully compatible with the Generation 3, and Generation 4 MakerBot® Stepper Driver electronics. 1.

What is TinyG – and why? – Synthetos
TinyG is a many-axis motion control system. TinyG components execute G code directly without the need for a general-purpose microcomputer. TinyG is meant to be a complete embedded solution for small motor control. The design goals are to build a board that can handle most motors up thru NEMA23 and be networked for multi-axis motion control well beyond just 3 or 4 axes.
Grbl development log
First complete job … completed I finished a little Air-app to stream complete jobs to the Grbl and render the result. This is the first “full scale test” running some 7000 lines of sample G-code I scrounged from this thread on CncForum . The Air-app feeds g-code to the microcontroller one line at a time, while the microcontroller generates the steps and feeds them back to be simulated in the Air-app.
Building a drawer slide CNC machine for under $200!
Drawer Slide CNC Machine for under $200 Like many of us interested in this hobby, I wanted my own machine. But I didn’t want to dive into it, spend $2k plus and have a large paperweight out in my shop. The idea was born for a simple, cheap, somewhat accurate CNC machine that I could modify as I gained knowledge (and funds). The first step in the process was deciding what hardware I was going to use.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.

Are you using an optical mouse right now? Ever wanted to see your desktop through the eye on the bottom of it? Me neither, I already know I have to clean my desktop :-)
OK, so I finally decided to get my hands on the Arduino platform and see what all the buzz is really about. And I must say, I'm impressed. This is by far the most developer-friendly development platform I've ever seen. It's main advantages : It's simple.

Friday, November 19, 2010 Amateur CNC mill show and tell Thought I’d have a go at something a bit mechanical for a change.
howie m » Amateur CNC mill show and tell
While I have understood the basics concept of CNC machining–and have utilized it in my work–I never fully appreciated how complex a system a CNC machine is until I set about designing and building one. There are many software and hardware layers are involved in the process, and each of these layers offers nearly endless options to choose from… CAM software, controller software, steppers vs. servos and their torque specs, power supplies, motor controllers, breakout boards, encoders, etc. not to mention the mechanical modifications to the manual mill. So as a first step in converting my milling machine to CNC I looked at a lot of other people’s conversions with this and similar machines, especially in the copious posts on CNCzone.com and specifically the great work that “Hoss” has done .
