Hi,

I got hit by a badly heating extruder stepper motor. On the default current of 500 mA the temperature rose to over 90°C, and even when reducing the current to 100 mA, the temperature remained high. Since I have to run the axis steppers in microstepping mode 8 to avoid noise, I might as well switch all of them to more compatible ones.

Question: which steppers should I get? My only specs would be NEMA 17, probably 1.8° per step. Should be suitably powerful to run a delta printer with decent speed and acceleration. Maybe we could compile a list of recommended steppers in the wiki?

I use these steppers on my printer. Plenty of power.

Depending on where you are, I got my delta kit from http://www.builda3dprinter.eu and his motors don’t heat up at all. My drivers heat up more than the motors, running at .5 or even .7A on my reduced stepper for the extruder.
