In trying to figure out whats wrong I did the following, I un-plugged the x -stepper and manually moved it to its home position in the initial sequence before printing a part, no vibration as it moved to through the y direction, then I plugged back up the x-stepper and unplugged the y-stepper and manually moved the it to its home position as before, no vibration as it moved to through the x direction. Any body have some ideas, I was going to order a couple of steppers and some other stuff to try and get it back up and running, what other parts would need to be ordered?
