Hello guys and if there-s any girls :) I'm in "maybe" little problem. I've made circuit like in example for Optoisolated stepper motor controller. It looks like this and I took a stepper motor from the scanner which have this caracteristics Items M42SP-7 Rated Voltage DC 12V Working Voltage DC 10.8~13.2V Rated Current/Phase 259mA 173mA No. of Phase 4 Phase Coil DC Resistance 50Ω/phase±7% Step Angle 7.5º/step Excitation Method 2-2 Phase excitation (Unipolar driving) and have 5 wires which are> red, black, brown, yellow and orange i've readed little bit about wireing of steppers and that the phases(wires) of stepper must be in some strict order so I tryed and tryed and it doesn't work, everything that i can get out of stepper is that he vibrates or nothing. ps i have winXPpro and parallel adress is 378 checked in bios and there is something about parallel port (ECC ...) I'm sorry for my english, and I hope that someone is going to help me about it Thanks to all
