No job running but overheating and they not move. For quotes, and questions please message me at S My stepper motors definitely get hot during prints, and I know there is a way to calibrate the voltages to make them run cooler, but what really counts as "too hot"? I can leave my finger on the motor for 5ish seconds but after that it starts to hurt. So I made a control system where I can control the stepper motor to turn in certain angles through an Adafruit LCD Shield buttons input. 4 posts • Page 1 So design engineers (and motor end users) must find ways to maximize motor torque while avoiding motor overheating. The motor is rated at 0. Ok so here's where I think I wasn't clear and caused the misunderstanding: the driver provides full current both when the motor is moving and when it is idle; if the motor sits in a fixed position for a long enough time (idle, or like in the case of the Z motor, for most of the layer height) it will heat up more. We’ve compiled a list of things you can do before you replace the motor. Hi I was wondering if it was normal for the motor component of a stepper to get quite hot? I'm running 5v direct from a 12v -> 5v 30amp dropper with ground from there too. If @hitman47 calibrated his e-steps with the gear ratio then he cannot. DRV8711 drives the stepper motor to generate severe heat.
