i have sculpfun S3o Pro Max its suddenly start noise y Axis only Side motor i check belt and baring all are ok when i move by hand its move smoothly when i take frame then the motor moves but to much noise its like some thing jam inside and when i cut round circle its cut oval shape, i update its firmware still same issue please to fix this error.
I would be checking the set screws on the y drive pully and coupler with an allen wrench. Something will be loose.

I unassembled complete machine to diagnose the issue but all screw are fixed and fully tied machine is working fine I cut 1 piece they I place 2nd piece its starting noise too much and file not cut properly. only Y Axis issue this but when i move y axis by hand its move smoothly .
Have you made changes in the GRBL parameters, perhaps to enhance performance?

no how to change parameters any guide please
what i set Y Axis value to increase the power.
Here is my machine video problem
@Dskall Here is the video that issue I faced . X axis perfect working Y axis making too much noise and cutting not perfect please have a look this video.
That appears to be intermittent mechanical resonance in the Yaxis. Otherwise, it seems to be operating fine.
There is a long metal rod that connects both ends of the gantry. Try this…
In a couple of places, not evenly spaced, wrap some masking tape around that shaft. Wrap as much as you can without it rubbing something.
If this does not stop the noise, you might have a bad, or possibly loose, bearing on one end or the other.
In any case, you are looking to solve a mechanical problem.

I think its motherboard issue when I shuffle X cable to Y cable so Y axis working perfect and X axis start noise. is there any option to reset board software.
Don’t know your machine but Y driver current may be set to low since it also doesn’t cut right and maybe missing steps.

You missed telling that you are using the xy-extension kit. Did you adjust the reference voltage on the y-axis driver by the 90° turn? If so, you might have killed the driver, that’s correct. Since those are soldered to the board, you need a new mainboard then. Next time, adjust the vref by turning the potentiometer only 45°, not 90° as the tutorial states.
