Duet 2 wifi : Z stepper port max amperage

[Lamenkun]

Hello,

i need to plug 2 E3D Stepper motors to my Duet 2 Wifi Z stepper port,
the document noted that i have 2.4A Peak per stepper channel,
the two Z stepper port is in serial,
my motor needs 1.68A each,
could i plug they to this two ports ?

@Lamenkun Yes. When wired in serial, the stepper motor current is the same for both motors, while voltage is doubled. The stepper driver sets the voltage to achieve the current setting automatically.

If the motors were wired in parallel, you would need to double the current, but they are not, so don't.

@droftarts many thanks !
