Z axis movement Broken?

uArm Swift (Pro) Troubleshooting
1

I am experiencing very limited y axis movement on the uARM, the arm moves along the X axis fine, however when I try to lower the uarm, it does not go nearly as far down as it is supposed to. Which servo is responsible for the up/down movement of the arm?

If i placed the uarm on the table it used to be able to lower the vacuum pump and pick up an object, now the movement only gets half way down to the table.

I cannot calibrate it either: http://pastebin.com/raw/WgU6x0Xm

As you can see servo 2 and servo 3 have issues, I cant finish the calibration either because I cannot manually move the uarm to the required position (end affector touching the left foot)

No reply after 11 days… Excellent. So can anyone at ufactory post a link of where to buy servos?

Thanks Cleo, unfortunately this did not help. Where can I get spare servos?
