Lulzbot Taz 6 upgrade Hemera stepper motor not extruding filament

A problem has arisen with the new upgraded Lulzbot Taz 6 Hemera stepper motor not extruding filament. (I.e. gearing is not rotating at the set temperature e.g. PLA at 200 0C).

 The E-steps and firmware updates have been applied successfully through the Graphical LCD - (LulzBot TAZ 6 | SE | 0.5 mm-(Aero V2).

 Filament can easily be extruded by hand, indicating that the nozzle is free from restrictions.

 All the Molex 4 / 16 / 20 two row connections appear to be sound with only the power to the stepper motor being affected.

 With the re-installation of the Taz 6 Aerostruder extruder the printer functions perfectly.

 I have checked through the E3D forum hoping that I might have found an answer.

 I am not quite sure as to what to try next?
