Nema 17 Stepper Motor is Noisy, or Rattling?

- If your stepper motor isn't moving smoothly, it could be that you haven't wired it up properly. Not all motors are the same, make sure you check the data sheets to see how it should be wired to the controller.
If you can't find a datasheet, then you can measure the resistance across different leads to find the coils. On all the Nema 17s I have seen, there are 6 leads, and the 2nd and 5th leads are left generally left open. Then you can measure the resistance between the other leads to find the coils. If the leads you are testing show an open loop, then those are not on the same coil.
Once you have found the coil, it doesn't matter which lead goes to where; ie A and A' can be swapped without any adverse effects.
Let me know if you have any questions. I'm happy to help.

I'll have to look into this, since my last was nice and quiet. Though I swear mine is wired correctly per the data sheet, but the proof is in the puddin here
So this was my problem, thank you!!
thanks for saving me a giant headache
Thanks for the video. I'm helping my friend with his 3d printer
saved my day
Thanks
So this is it huh… I’m having that on the rail of a 3d printed robot arm
do you know how to thoroughly test a nema 17 motor? i dont mean the basics i mean my motors seem to work but they are making weird noises when homing which is low speed i would love to know how to thoroughly test them
Is it necessary to shot grd pin and en pin of cnc shield...?
NEMA 17 is simply a form standard.
I have the same problem 🤨
dear sir , thank you for sharing the video , could you please tell me where did you get the black gear mounted on the motor from ? am trying to build flat surface to mount another stepper motor on top of it
They're just 3d printed gears.
what pins?
@Chase Madison which stepper motor you recommend for wind turbine that can produce with out put at least 14 Volts and 150 watts?? thank you God bless.
One that is not a stepper motor.
Can you give Amazon link of silent motor
a bit late - its not the problem, the problem was how it was wired
Your triggering your overcurrent with the first motor? That's a lot of current driving nothing? What driver you using?
i saw this too, confusing
Oh Thanks, do you have a code to controll this motors with a l298n and a raspberry?
Greetings Eric
I was using an Arduino and the "Stepper" Library. This looks like it might be helpful though: projectiot123.com/2019/01/29/raspberry-pi-gpio-pins-with-stepper-motor-using-l298-motor-controller/
quick tip! stepper motor drivers can be had very cheap online
ok
Isn't it said that you should not disconnect the motor while the power still ON... Doing this will damages the Stepper Driver ?
yeah, i was surprised
i am facing the same problem had tried all the solutions changing wire combination, code, pins drivers but the motor is still sometime gives a beep only or rattles with beep and the strange thing is that motor is showing continuity in all four pairs, led blew up no matter what the wire combination is it show continuity on pairing 1,2 -1,3 -1,4 and so on for all. I had tried running motor directly with arduino without motor driver and it is running, but facing issue while it is connected to CNC shield with A4988 driver.
I am using Arduino uno and motors are 4 pinned. Could you please tell me what I am doing wrong?
Without seeing the code, how it's wired and everything I can't tell you what's wrong. Make sure you have external power for the A4988 and give it at least 12v. Make sure you have a capacitor between power and ground. You can test where the coils are with a multimeter. If you test two wires and they are on the same coil then they will act like a wire with very low resistance (it is a wire, just wrapped around a bunch of times).
@@chasemadison I am sharing the code below I had checked the wires that are on same coil and then connected the same wire to the a4988 driver had checked the voltage it is around 12.63 - 12.71V. Just tried driving the motor without driver on a code pre provided in arduino examples for "Stepper One Revolution" but the motor is just vibrating and not moving at all. codes that I had tried are given below
But the strange thing is all the coils are connected with each, I had checked with the multimeter in the continuity mode and it is showing continuity in every combination idk why.
code 1:
const int stepPin = 3; //X.STEP
const int dirPin = 6; // X.DIR
void setup() {
// Sets the two pins as Outputs
pinMode(stepPin,OUTPUT);
pinMode(dirPin,OUTPUT);
}
void loop() {
digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction
// Makes 200 pulses for making one full cycle rotation
for(int x = 0; x < 200; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(1000); // One second delay
digitalWrite(dirPin,LOW); //Changes the rotations direction
// Makes 400 pulses for making two full cycle rotation
for(int x = 0; x < 400; x++) {
digitalWrite(stepPin,HIGH);
delayMicroseconds(500);
digitalWrite(stepPin,LOW);
delayMicroseconds(500);
}
delay(1000);
}
code 2:
#define EN 8
//Direction pin
#define X_DIR 3
//Step pin
#define X_STP 2
//A498
int delayTime = 30;
int stps=200;
void step(boolean dir, byte dirPin, byte stepperPin, int steps)
{
digitalWrite(dirPin, dir);
delay(100);
for (int i = 0; i< steps; i++)
{
digitalWrite(stepperPin, HIGH);
delayMicroseconds(delayTime);
digitalWrite(stepperPin, LOW);
delayMicroseconds(delayTime);
}
}
void setup()
{
pinMode(X_DIR, OUTPUT); pinMode(X_STP,OUTPUT);
pinMode(EN, OUTPUT);
digitalWrite(EN,LOW);
}
void loop()
{
step(false, X_DIR, X_STP, stps);
delay(1000);
step(true, X_DIR, X_STP, stps);
delay(1000);
}
@@hppavilion6484 Sounds like you have the wires screwed up. Or possibly the Step or dir pins mismapped. I'm sure you've looked at this: www.makerguides.com/a4988-stepper-motor-driver-arduino-tutorial/
@@chasemadison Tried these instruction but in vain. The step and directions pins are matched correctly I had tried changing step and direction pins to make sure that there is no problem with those pins but that didn't work as well. I had followed the instructions provided in the link and uploaded the code provided in the link, the result is when I power all things up after connecting, Motor gives vibration only (Shaft didn't rotates) and completes a full revolution and then a delay and again gives vibration (didn't rattles only vibrates) and shaft didn't rotates. I tried unplugging the direction and step Pin while motor is powered, after doing so the motor vibrates and rattles a-lot continuously but the shaft of motor also moves a little bit . But in the case when all the pins are connected motor only vibrates (not rattles) completes its one cycle in CW direction then a delay of 1s and again completes 2nd cycle in CCW direction without any rotation in the shaft.
Hope you understand what I am trying to explain. Thanks
Another update is that when I plug Only any two wires of motor with the driver and other two remain disconnected then in the very first Iteration when the program starts motor rattles vibrates and shaft moves, then in the upcoming loops the motor only vibrates rattles a little bit but the shaft didn't moves and when it comes back to the starting point of loop again the motor shaft moves it vibrates and rattles, same scenario happens when I connect 3 wires of motor and 1 wire remains disconnected but when the all 4 wires are connected motor only vibrates and shaft isn't rotating
@@hppavilion6484 Did you say you were able to get it working with a different sketch? Not using the stepper library? Can you upload a video or something of what your wiring looks like? Also, it's possible you burned out the controller chip. I bought 5 of these and before I knew it I blew out 3 of them just trying to figure out how to get things working properly.
hey you wanna help me build a automatic cigarette injection machine and put it up as open source for people to build and improve???
whats cigarette injection?
tip for you, learn to use camera, 60% of the video is black
and audio too
Weird. I don’t have that problem..
@@chaseroberts4775 the camera is in portrait mode, of course you have the same problem.
@@Ayce47 Yep🤣
