Bondtech Raise3D Dual Direct Adapter
The kit includes two adapter cables.
Older model Raise3D N1/N2 printers with the silver color motors have a stepper motor connection that does not fit the motors on the Dual Direct Extruder, so an adapter is required in order to connect the new Bondtech Dual Direct Extruder to your early model N1/N2 printers.
This adapter fits onto the factory extruder stepper motor cables and then plugs into the motors of the Dual Direct Extruder. One of the cable adapters has the phase shifted on one of the stepper motor coils. This phase shift is in order to change the rotation direction of that motor and is necessary in order for the extruder to feed filament in the correct direction.
