Strange print issue

It was about 9ish hours into a print this morning when I happened to notice the nozzle seemed to be stalled on top of the print.  It struggled for a moment then raised about 10mm and continued to try to print in mod air.  The reported Z height on the display was correct for the model but not accurate to current position.  Printer has 52 days of print time and I have not seen this issue prior. 

where should I start with this? 

thanks!

RE: Strange print issue

Did you have any power issues?  That would be my first thought.  You might want to check your connections, the Z axis may not be getting proper signals.

Cheers

No power issues as far as I can tell.  I did order new nuts for the z axis just in case it slipped though it seems okay.  It has not done it again since this incident.  One really strange thing I noticed today was it now shows 104 days 17h 57m print time in statistics.  This just can’t be correct or even in the ballpark.
