Thanks for the advise. I wondering if may be a problem with the RAMPS board or Arduino. The Y tower is the one I am having problems with. The X and Z work fine. I can switch the Y and X tower's motor and driver and still have the same problem. The motor and driver that works fine in the X tower will make the same sparatic movements and loud noises when installed in the Y tower. The Y tower motor and driver will work fine in the X tower. No changes were made to the pots on the driver chips.
To eliminate the chance of the belt hanging up and being cause of the problems on the Y tower, I removed the belt and unscrewed the motor from the tower. The same lound noises and sparatic movement happens no matter which motor and driver are plugged into the Y location of the RAMPS board.
