The motor comes with four 30cm long cables connected which is compatible with the majority of electronic components, from RAMPS
These NEMA 17 have a rated power consumption of only 5W, and are specially designed for use in conventional 3D printer Z axes, as a substitute for shaft couplers
and threaded rods.
The main advantage of this system is that the special nut together with the lead screw prevent backslash, which leads to a better 3D printing quality since the thickness of the layers can be controlled with a high precision. At the same time, this permits a higher positioning speed on the Z axis.
The price is for one unit.
