Help!Calibration uArm

Hi, seema. Could you please tell us more information so that we can find the problem.
which is your uArm version? Metal,Metal alpha or acrylic?
Which version of Arduino code did you use?especially where did you get code?(Paste the website)
we also need to know how the problem occurred? Please describe the details. thanks a lot!

Also having problems with calibrating metal v1.
Tried to follow instructions but in power up the arm violently snaps back toward udiono dislocating arm. Right hand servo remains on and makes a sound like its still on when everything had stopped. Has the servo blown or has it been installed incorrectly?
