Hi
I am new to cnc router. I have completed one small project but now after that i am facing noise issue from stepper motor and my Y axis is not working in correct direction as earlier. It is going to y+ and y-  coardinate with one left arrow key.
I am using Windows xp sp3.
Please advise. Thanks

You can change the direction by ticking or unticking "DirLowActive" in ports and pins | Motor output.
(see attached)

Newbie,
Drives and motor tuning need to be set properly.  The noise will go away.
Do some reading on the basics.

Could you print screen your motor-tuning page for Y-axis paste in paint save as a PNG file and upload here.
We also need to know your stepper driver model and your Break out board model and your power supply model.
