Problem(s) Encountered:

The guide probe stopped responding and would not leave it''s current location.

I followed the instructions here and reset the system:

I did not get a chance to check if it solved the problem as high humidity

caused me to close up.

Solutions:

Tested out the guide probe this morning and still found it to not be functioning properly.  Tried closing the GUI and power cycling the MIS.  After this, I was able to move the guide probe again, but it would not travel all the way to the demanded values.  Thankfully, OSMOS allows for access to the guide probe so I checked and found that the probe was in a very odd position.  While the GUI registered that it was at the origin, it was actually so far north that I could not reach the motor mic.  It was clearly lost.  On the xmis2 GUI, I reset the MIS by 2.4m Setup>Reset MIS which drove the guide probe back to its home position.  It now appears to function as expected.
