Well, yesterday i was cleaning the basement of one of my friend's house when i found this:

A very good looking box with a lot of interesting stuff in! Motors, mechanics, gears, belts...and whatever people can drem up! Perfect for some cool robotic projects! So i brought everything in my house and i started testing it. I have no idea of where all this stuff came from, it seems a sort of photocophy machine, or something like that. All the guesses are welcomed!

Hi all,

I've been working on the driver for the next CNC, V3.

This one should be able to drive bigger motors up to about 2.5 Amps per coil, while providing current limiting.

It's features shold be the following:

- wave, full and halfstepping selectable in software

- I2C and step/dir/enable interface available on board

- home sensors connectors

Below is an iamge of the PCB I layed out:

I ripped apart a couple of flat bed scanners looking for gears. So I have two stepper motors in my kit box that takes up valuable space. If anybody got inspired by this and want to give stepper motors a shot, just give me your adress and I'll send one your way for free in about two weeks (vacation atm).

Edit: BOTH STEPPERS ARE GIVEN AWAY NOW
