DIY csCNC – 2 (Linistepper driver and testing with Bus Pirate)

via Dangerous Prototypes

diy-linistepper-4

Oakkar7 has a nice build log on his DIY csCNC, he writes:

Since I started building DIY CNC, I checked the free, opensource motor controller. There are several alternatives. I chose linisteppr controller.
– Simple and cheap (my first priority :) ) and I can source required parts locally
–  microstepping, open design (Especially, it’s PIC16F628A based. I’m PIC guy and a lot 16F628A in my stock)
Build log is fast, simple and straight. I used a simple perfboard for faster development.

After building the driver, I tested it with my buspirate using PWM function for generating stepping pulse. I started with 1kHz and increased to 4 kHz.

MM - 3D EDM 1Take any 3D printer, throw on this modular head, and use it as an EDM machine to do precise metal carving. Exciting stuff! What’s EDM? Electro-Discharge Machining or “spark erosion” is a fairly specialized field that not many hobbyists are familiar with. The technique flips traditional electrical design upside down […]

MakeSmith CNC

via WyoLum Blog

The rest of the WyoLum crew get to have fun with laser cutters and 3D printers to build cool and interesting Open Source goodies for everyone. I figured I needed to get in on some construction action too, so I recently purchased a MakeSmith DIY CNC machine (www.makesmithtech.com) from their recently completed Kickstarter Campaign (I love Kickstarter…;-). It’s a very low cost entry into a small scale CNC set up (work area approx 9 inch square) for hobbies etc. and I couldn’t resist the idea of trying it out. Over the next few months I thought it would be interesting to post some updates to the blog detailing how I get on with putting it together and what I end up using it for..
