Homebrew driver schematics?

[Konstantin]

Hi everybody.
I kinda sorta wondering about making my own driver boards, it sorta happens sometimes, I think I just fantasy about it.
Since I have never done any electronic project successfuly I probably should stay away form that kind of job.

So having edited my original posting I will better spend my time on finding the right driver board for me future project.
Thanks all.

I build my home made driver and power cards yesterday. I get the plans from http://www.otocoup.com/CarteL6208_e.htm prepared by a French man called Pierre.
there are some photographs about my home made card at http://gunol.otocamlibel.com/cnc (this page is my own page)
please check these pages. I beleive that you can build your own cards easily. Good luck

nice design; bit low on amps for my project; but I might make the controler board

Wow, that is so far the best looking homebrew controller board I have seen. ? Thanks for sharing gcamlibel.

I see on your web site that you have made 1 axis board then 2 axis board and then 3 axis board. Have you encountered any problems?
Is that design protected from the voltage coming back from the steppers to the driver board?

Edit:
I just found this modular design http://www.hans-w.com/modular.htm , have anyone tried it ?

Try this it's a better design I think, 3amps and up to 55volts. The nice thing is it is a microstepping chopper driver board. Software is open source and the design works great. Very smooth at 8 microsteps.

And if you need unipolar driving but beefy amperes (success with 5A/winding, capable of more) maybe this can be useful:
