Solved Print failure analysis anyone?

Would appreciate ideas on what went wrong here. After finally having a few relative successes with smaller parts of the R1 from Mike Kelley's Thingiverse posting (examples included), I decided to print a 5 hour "monster" overnight, the X axis motor mount.

I'm using a stock R1 (non plus). I am printing this on a "medium setting / PLA" settings with the current version of the Robo version of the Matter Hacker software . The only changes I made were to accommodate the Z-axis, and to add a raft and change the infill to 75%.

The raft and initial layers seemed to get started OK, although that's harder to see, so after 10 minutes I walked away. But I'm guessing about 20 minutes after I walked away it all went south. You can see there is a middle portion that looked normal, but then it all falls apart again.

As a side note, I'm printing this direct from the SD card, so not a PC communications issue.

 

Meant to close out thread earlier, Cleared up major problems after completely resetting the matter control settings. No longer getting prints that look like winter snowscape scenes, must have been a settings glitch.
