Would a 0.9 deg/step motor still run ok off this controller? The guy that built it said he had to swap out the 100K variable resistor for a higher valued one to get the motor to rotate at 1 RPM. I'm gathering if I use a 0.9 stepper, I may have to replace the resistor with the original 100K? I'm also gathering a 0.9 stepper will take smaller steps. Is this correct L? Thanks for the scanned article BTW.
