one camera losing calibration

What electrical network are you connecting, and how?

Sorry for the delay. As far as I know all our gear is on the same power line which is old (220V 10A). The gear consists of two computers, audio interfaces, a teleo processor with two small motors and the hubs. I've been using the system just taking into account this issue and it worked relatively OK. However, when I turn an object up to 180 degrees (or 179.9 to be exact) the angles start to jump to wrong values since the quaternions are incorrect at this point (any idea why?). This is an issue I sent before directly by email and I'm still waiting for an answer.

It's possible that poor power quality could interfere with the hub's operation. Stabilizing this may help.

With reference to the quaternion issue, as stated through email we have made some minor changes since version 2.3.0, however, it is possible that the issue is caused by your transformation matrix. You can find conversion information used in Tracking Tools here.
