Hi,

I'm new to CNC zone but for many years I have run a small company in Cyptrus producing CNC plasma and router systems, mostly custom designed.

We have designed in-house all the electronics, mechanics and software

As I will be retiring soon I would like to contribute some of our designs (electronic mechanics and software) to your community

My first contribution will be for an inexpensive uni-polar chopper stepper drive capable of up to 80v 5A with faciltiy of using with microstepping translator.

If this is of interest to anybody please contact me and I will post details within the next few weeks.
