Stepper shield and AI noise

Hi Wawa

Sorry for that, here is links from parts:

I thought that the stepper motor coud not be powered with a 24V supply to the shield.
Do you think that I can supply the shield and motor with 24V?

Why.
The shield shows 8-35volt and the DRV8825 is 45volt max.

Don't know why you have choosen a 2.5A stepper motor for a 1.5A max driver board.

Hi Wawa

Thanks for your teachments.
I will try today powering everything with 24V without the stepdown.

Hi

After removing the stepdown regulator, and powering stepper and laser with 24V DC, the noise is the same. Without powering the stepper shield the noise is almos nothing...

Ok, not that, but use without buck converter anyway.

Did you already try a different ground for the sensor.

Hi Wawa

I try in different places for ground but is the same.
I will try powering the shield but disconnet the motor, to see if the noise comes from the motor or the shield.

Dear all

I am still trying to resolve this issue
Can someone suggest a better stepper driver that could eliminate/reduce the noise from the stepper motor into arduino signals?

Best regards
