Hi friends,First of all I am newbie in electronics, In my project i need 2 stepper motors and 3 servos. At present I have successfully made working 2 steppers and 1 servo, however when I added 2nd servo, my main stepper(stepper motor no 1) started fumbling i.e. i need to give a push to make it move. But when I removed 2nd servo it works fine. That is 2 steppers and 1 servo works fine.
I think my transformer/power supply is short of capacity. My transformer is of 1 amp, 12 volts, my servos are Acoms IC AS2. I don't have any identification for my steppers. All steppers and servos are given individual power supply. Can you suggest me how to overcome this situation. Let me know if you want further information.
Thanks in advance.
Without knowing the draw of all the devices it's impossible to say. Have you hooked up the multimeter to see what the current draw is? Have you tried a power supply with more current capacity?
