The teqc tool from UNAVCO can help with diagnosing iffy data.  Can you put
your RINEX somewhere?  With the antenna in an unobstructed area my Z12
routinely gives 1 cm-ish horizonal, few-cm 3D, using OPUS-S or OPUS-RS.

Conceivably there's some reference-clock problem with your Z12 that's
trashing the phase observables.  As another check, let the unit cool to
room temp, then power up and see if it tracks.
