[muffu]

hi,
i have a geeetech prusa i3 pro b with a mk8 extruder using a 42SHD0217-24B stepper. how much
voltage can i give the stepper? at the moment it has 1.16 volt, but sometime he loses steps.

greetings muffu

Hi,the rated voltage of this stepper motor is 3.75V and rated current is 1.5A.

hm
i am not an expert - you mean i can set the screw on the a4988 to 3,75v if i measure from the screw to gnd?
sounds very much compared to the ≈ 0,9v for the x,y,z steppers?

No,that's not what I mean.I am talking about the stepper motor.If you mean the A4988,its normal range is 0.8V to 1.2V.
