Driving a DC motor as a stepper is not possible. I believe the original
poster wanted to operate a machine, and could not afford stepper motors
in his country. The alternative is to use DC motors, and *something*
in between the computer and these motors, to make it all work.

The Gecko servo drives accept step and direction pulses, so the computer
thinks it is driving a stepper motor.

So, the computer thinks it is driving a stepper, and the machine moves.
I think this is what the original poster was looking for, even if he didn't
phrase
his request in exactly those terms.

If he really wanted to warm up a soldering iron and convert a DC brush
motor into a stepper, it is just about impossible. A 'DC' brushless motor
is closer, but it would be a very coarse stepper.
