S5 - Out of bounds movement Error

[UMS5_VSM 0]

I have an S5 that's been running well for about 2 years now.  Recently, the printer has messed up on two different print jobs with the same action.  After 30mins to an hour of printing, the print head appears to have traveled behind the Print Core Switch bracket and gets stuck causing a horrible noise.  Eventually, an Out of Bounds movement error is displayed which forces a reboot.  I have experienced this on two separate prints that have run flawlessly in the past.  The only new thing on the printer is the updated firmware:  7.0.2, since the last time running these files.  One strange thing that happens is that the active filament feeder grinds a spot like its stuck and then retracts it from the head.

 

I just reset the printer back to default and will try to run another test print.

 

Has anyone else experienced this and by some random chance is this a bug with firmware 7.0.2?

 

Thanks,
