My dear friends,
i have done the famous circuit for drive one stepper motor (on a breadboard)
**broken link removed**
the issue :
the motor not stable (Vibrate strongly AND random turn left and right )
but when touch any Non-insulated wire by my hand , the motor Works regularly!!!
please, what is the problem?????
i used:
* 24 volt , 500mA (printer power supply) .
* unipolar (5 wires) stepper (NMB PM55L-048-HPG9) .
* zener 8.2 volt .
* diods 1N4007 .
* MOSFET 6N60A .
* Capacitor 220 µF 35 V.
* Mach3 program.
