Arduino Uno and L298N motor driver

[okodesign]

Hi. I am trying to fix a problem, where when using the L298N motor driver with Arduino Uno makes a horrible loud noise. I have a laser burner XY axis rig which when operated using the built-in board does not make any strange noises. The above issue occurs when I try to connect its stepper motors via my combination of Arduino UNO and two L298N motor drivers. For details please see the images and diagram. Any suggestions on how to fix this,

please? Thank you!

I need a microscope to read the diagram.
Do you think you could make it a little bigger?

Hi Jim_p, sorry if you know this feature.
If you click on the image it appears highlighted and then click on it again it appears in full size.

This way you can clearly see the OP's schematic.

Again, I'm sorry if I'm being bothersome.

@okodesign
Are you powering the module's logic using the jumper on it?

Using the appropriate tags, I suggest you post your project code.

What stepper motors are you using? Please show their technical specs.
Most steppers cannot be driven with the ancient L298 driver.

Thank you for all your replies. The stepper motor that came with the 'rig' is marked with the following: 42bygh34hy27d

The schematic looks nice in miniature but there is not much there. The two grounds of the Arduino are connected, nothing else. The schematic needs to be completed before it has any value in solving the OPs problem.

A 42BYGH34 is listed as 2.8volt/1.33Amp.
The L298 is the wrong choice for this motor. It will try to draw ~4Amp per coil from a 12volt supply. You will either burn the supply, the driver, or the motor with this combo.

A CNC shield with current controlled DRV8825 drivers could be a solution.

Thank you for the suggestion. I'll go ahead and try the DRV8825 . Also, I plan to connect a servo to the 'head'- the ultimate plan is to make this into a scribing/ drawing machine. Any suggestions on how to go about that? Would the servo need another controller- what kind and where would it connect to Arduino (and also what kind of servo? I am sorry for all the questions- learning as I go along.
