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

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.
