HI
here is a clip OF stepper driver with L297+7409+IRF520.
I hope to take pleasure.

A very good effort.

Hi Nasr1,

Do you know any open source stepper motor project by which i can control my old cnc machine having steppers on it and using mosfet's

what volts and amps you need for your steppers. I have slightly changed a current chopping pminmo design for 100V 8amps per phase for unipolar motors. If interested drop me a pm.

Hi Nasr1.

Have you actually made the board you posted a schematic of..???? I am inetersted in finding out how did the irf's peformed and what kind of performance did you get out of it ...
