You already found the answer, but those JST connectors are widely used in Japan, and perhaps less common in Western designs. More info here [en.wikipedia.org] If you are using crimp terminals, then...

Not sure what you are asking for. In a lathe the spindle turns continuously at a set speed, so it is more like a tool head than an independent axis. A 3 or 4 axis CNC mill with a rotational axis is...

I've noticed that you can get surplus NEMA-23's cheaper than the NEMA-17's sometimes. Probably because the surplus dealers KNOW that the 17's are wanted by the reprap builders. If you can modifiy your...
