My CNC (ex)router

My project began just as most - from having fun of drawing

I found some material in internet and check others projects. Well, it turn to not be the breaking bone practice so i deside to order parts and to give it a try.

As you can see from the upper pictures i start with the mistake - bought ready board with toshiba chips made in RC. On theory that should work well. In practice .. no. So,if you wish to try similar, skip that one and buy proper drivers.
I took my attention on Allegro chips, in face of PCB board that Pololu offer. Absolute enough as power potential for my steppers. Then i design some small board to combine all in one, take some other parts, computer,cables and box. And finally i got what i want for first test.

And then come the first result of the tests..

Unfortunately the project wen away and was sold.. but hope one day to build new one with better materials and motors.

    By the way, those anti backlash nuts seems to work very well. Actually there aren’t backlash at all. I was suspicious about those, but for no reason.

    Same design is used in normal old turning machines but nut has been made from brass.
    In case of backlash only adjust ;)
