Need Help!- Stepper Motor doesn't spin but makes noise

[Finder]

Hello everyone,

I am trying to connect stepper motor to the driver.
For some reason instead of turning it makes noise.
When I increase voltage the noise becomes louder but motor still doesn't move.
I am wondering what could be wrong.

What kind of noise does it make; buzzing or screaming?

The noise maybe the motor moving but very slowly, try jogging at high speed.

Ок, I was afraid to raise voltage more but curiosity was stronger then fear.
I increased the voltage at ohhh yes it is turning!

[Oldmanandhistoy]

Increasing voltage will only give you more torque at higher rpm’s. If it is turning very slowly and makes a buzzing sound you need to increase the step pulse to increase speed.

What kind of driver? What kind of motor? What is the power supply voltage?

I'm having the same problem.
using EMC2, 24v supply, which is the rating for the steppers, and is within spec for the driver board (12v-36v).
the noise coming out of it is just like the noise it would make if it were running, and holding it, it feels and sounds like it's trying to move, but the shaft doesn't actually move. stepper is not seized. brand new, and can turn with hand. when powering up the computer, the steppers all "hold" well, then release when the boot up is finished. Not sure if it makes any sense, but it almost seems to me like the steppers are trying to move, but are being held or something. The frequency of the noise is coordinated to what it's being told to do, with accelleration, microstepping etc. it all sounds like it's running, but the shaft won't spin. tried multiple (identical) steppers, all teh same, and on all 3 axis I'm using. triple checked wiring, and I think i have the pin layouts correct. i did notice my driver pin laoyouts have seperate pins for XYZ permission and XYZ Pulse, and the Permission ones make it actually do somthing, while the pulse pins dont' seem to. i know i probably don't have enough information, but this is a start in case anybody happens to fix "Finder"s problem, the solution will probably fix mine too.

Turn down your velocity and acceleration to very low values and atart there. Make sure you have the correct number of steps per unit configured. i.e. TPI - step size. For example a single start 10tpi at half step would be 4000 steps per inch.

ESTOP!!!
mine works now. the X "permission" is really an estop out. I'm relatively new to cnc, so i didn't put two and two together... at least not in the right order. so i just kept trying different pin definitions until it finally worked. if at first you don't succeed... part of my problem was my ignorance, and part was due to my pin descriptions being translated by someone from chinese that isn't familiar with the concepts of cnc, just a literal language translation. anyhow, this was my first post and i intend to get more involved in the future. Thanks again!!!

Estop won't keep the motors locked........

[nka3850]

yeah. like i said, I'm relatively new.
what i did worked, but I'm sure this is probably a case of two wrongs making a right.

[pminmo]

You got it working that is what is important. Doubt there is two wrongs as Estop doesn't work like that.
