Re: [CAD_CAM_EDM_DRO] DeskNC Windows version

It is rather trivial to build a stepper motor controller. Any PIC or other
good microcontroller can become a stepper controller with the addition of
just a little software. Somewhere I've got the code in C for one I did about
3 years ago to run an embedded printer motor with a PIC16C77. It would need
current limiting added to it and microstepping if you wanted to do that.

It wouldn't be very difficult to add ramping to the micro either.

Microstepping, I have no idea how to do. But if someone would explain it, I
could code it <g>.

But then comes the question of why. With the price of Gecko drives, it's
really not worth the trouble to build your own drivers.

later,
Larry E.
