I can complement a link constrain using move_group interface.

but when I try to complement two link constrain, I get error follow.

[ INFO] [1480650717.131249443]: Orientation constraint satisfied for link 'left_middle1_Link'. Quaternion desired: 0.784223 0.425559 -0.247735 0.377519, quaternion actual: 0.784137 0.425735 -0.248081 0.377274, error: x=0.000526, y=0.000242, z=0.000733, tolerance: x=0.001000, y=0.001000, z=0.001000

what should I do next?

advance thanks every help.
