Rebuilt the print head using some spare parts from a Lulzbot Mini (filament was stuck in printed body of printer).  Once I got it back together it printed fine.

Brought back in today after doing a bunch of cleaning and messed with the threaded Z-rod alignment.   Leveled the bed and is able to print fine again.
