I am looking at the Pololu DRV8825 stepper motor drive rated for 1.5A without a heatsink or 2.2A with cooling. The nema 23 steppers that I've found are mostly 2.8A. Is that the coil max amp rating or what it draws when driving it (clearly I know little about steppers)? I'm guessing this will overload the DRV8825. =E2=80=8B --001a1133c16edbf04405146a2658 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
