I actually bought 5 Japan servo co. NEMA17 steppers for my build. They are KH42JM2B-140G. They say on them DC5. 16V 1.2A 1.8degree /step. After getting the printer fired up, everything seems to work, however I'm just not so sure how fast everything is supposed to move. I'm using an ATX 300w psu, only connected the 5A 12v to my RAMPS.
The motors do get pretty warm only after maybe 5min of testing in pronterface. Should I be worried that these are 16v steppers? Anyone know if there's a way to compensate? After actually finishing my reprap I read its recommended to use 3.5v steppers. Of rather not buy new steppers right now maybe later on when I get some cash flow, but for now I hope I can use these.
