Yes, with Pololu Shield works fine. I wondered if there was some secret may be with Dagu, but if you don't know the exact reason, it can be anything) Nevertheless thank you for the reply and for your project!

Hello! i have a problem, when logic power on Dagu is NOT powered from Arduino, motors rotate easily in both directions, but when i connect logic power (5V) from Arduino, motors begin to rotate harder in one particular direction. Firstly i connected logic from 5V Arduino pin which is near analog pins, then i tried to connect from ICSP pins, same result. Then I've done everything exactly like you to exclude my mistakes, but it doesn't work.

P.S. Moreover i bought two Arduinos and two Dagus, I thought i fired smth, but motors bahaves on both.
P.P.S Everything works fine with Pololu motor driver shield and Arduino - motors rotate easily in both directons.
