Mini #2: 

Printed a test print fine.

Prusa:   

Printed a test print fine after cleaning a mess. 

Taz 3:   

Cleaned up chewed up filament and then found that the Z carriage was offset so I leveled it and also did a new bed leveling procedure.  It printed a test print fine.

Do not use your own slicer on this printer as the Z motors cannot handle high speed and the two motors will get out of sync which will cause the problem I found.  I slowed down the Z-rate on all the slicers in the hub.  Please use the hub's slicers and configurations.

Taz 5:   

Pulled out chewed up filament and then in printed a test print fine.
