I am running on a Prusa i3 and at higher speed settings only one of my motors runs. When I lowered my steps per mm in marlin the issue went away. Do you guys think it could be a current issue or a motor issue?

Thanks

What do you consider higher speed settings? I can run ~100mm feedrate if I want without motor issues. Have you tuned the step drivers? are you using GT belts? Have you unhooked the belts and made sure the slides are smooth and not binding? Are you using the small nema 17 motors or the larger torque ones? Marlin itself with the arduino ive run 150mm rapids no problem, but im also using the larger 17 motors.
