A problem has arisen with my 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 of the Molex 4 / 16 / 20 two row connections appear to be sound with only the power to the stepper motor being affected.
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 and would appreciate any advice?
