NEMA 17 stepper motors for RepRap

Description:


 

High torque (36 Ncm) NEMA17 stepper motors for RepRap 3D printers - such as Prusa, MendelMax, Wallace, Mendel90 - or other CNC projects/robots. The four 70cm long wires are ideal for connecting to Sanguinololu or other electronics. The extra length means no time-consuming wire extensions (I know from experience with motors with standard 30cm wires that this isn't long enough for most RepRaps) - these will fit even on printers up to 30x30cm build area no problem! 

These motors also have crimp connectors for connection to Sanguinololu (or similar) electronics pre-attached. This will potentially save you a lot of time if you have never attached such connectors before (it literally took me hours to do all the connections on my first RepRap). The ordering of the connectors are either Black, Green, Red, Blue, or the reverse (for forward and reverse directions). If you know the number of each configuration you'd like, let me know, otherwise, I'll send out a selection suitable for a Prusa, or whatever I have available (direction can be changed in firmware, x and y endstops can be moved to the opposite ends of the axes, or wires chopped and soldered in reverse, if necessary; each of these is easier than crimping in my opinion).

Select the number of motors you want in the quantity box below - normally Repraps use 5 motors (x, y, dual-z & extruder).
