Hello, just returned from a weeks holiday today so sorry for the delay but jgroom certainly has my +1 for the problem. Seems to me like the trimmer on the pololu driver needs setting... Have you tried to increase the current to the motor coils using the trimmer (little black thing bottom of the above picture) If not, be very careful with it, if you wack it up too much it`ll toast the driver. AND it is STUPIDLY sensitive. Turn it all the way anticlockwise and then slowly slowly turn in back around until both motors move comfortably. To set your other motor currents, push against the axis and you have the current right when you can`t quite stop the motors with your hands. I`ve tried to do the calculations and set it using the little voltage reference point but the method above works out better and is 100% easier. |

Thanks for the continued thoughts but my wife wanted to kit out the room for a second child which is on the way... and with the porch build and recently knocking out the fire place, we were running out of money and there was only one option.... I think you will figure out the ending |
