Do you have a bad stepper motor? How to easily test.

#3dprinting #steppermotor #creality3d
Do you think you have a bad stepper motor? Here is the simple way to test.
Stepper motors are commonly used in many different devices and applications, from 3D printers and CNC machines to robotics and automation systems. If you suspect that your stepper motor is not functioning properly, you may need to perform some tests to confirm the issue. In this video, we'll show you how to test if you have a bad stepper motor using a few simple tools and techniques.
We'll demonstrate how to use a multimeter to test the resistance of the stepper motor's coils and check for continuity between the wires.
By the end of this video, you'll have a better understanding of how to test if you have a bad stepper motor and be equipped with the knowledge and skills to address any issues that may arise with your stepper motors. So, if you're a maker, tinkerer, or engineer who relies on stepper motors, be sure to check out this video and learn how to keep your machines running smoothly.

TIP: (this happened to me) If you see one of the pairs of pins does not have resistance, I suggest opening the motor and checking if there is resistance in both pairs of coils on the solders where the copper wires of the coils are attached. If there IS resistance on both pairs, it means the coils are OK. Now, check between the solders where the coils are attached AND the respective pin (you can follow the light green pad on the circuit board). It is possible that one of those pads (either on the pin side, or the coil side) may not be making contact (it's broken). If that happens try to re-solder the pad.

This test showed me that I don't have a stepper motor!

Sorry, but one coil does not make the shaft turn one direction and the other coil make go the other direction. Both coils are needed to make the shaft turn in both directions.

Another simple test is to grip the extruder gear while its extruding, it should be hard to stop the motor, if its easy to stop then the motor is on its way out. Ideally you need two motors so you can compare the difference in torque.

Did you just say one circuit make it go one direction and the other circuit the other way???? Not exactly true, you know....

just bought one second hand and it wasnt working 🤦🏻‍♂️, thanks your video helped.

Wow! The Hulk shows us how it's done!

thank you! i needed this badly
