General Mach Discussion / stepper motors making "weird" electronic noise
« on: January 14, 2010, 07:11:51 PM »
3 axis wood router using xylotex driver and 497 oz.in. stepper motor. When moving running a file there is sound like electronica noise (its what a whistling cyborg would sound like). The steppers were not making the noise a week ago, I am not sure what has caused this issue. Any suggestions on how to fix it. Is this a shielding issue? If so.... my cords are shielded.

I am new to Mach3 and setting up a mill. I inherited a mill and I am in the process of putting it back together. I am a little confused; frankly I do not want to make a mistake and screw anything up.   The X and Y  Acme 3/4" x 6tpi and the Z has a 1/2" at 10tpi.    The y axis is driven by dual lead screws and has to belts running from the motor to the left and the right lead screw.  I am not sure how to do calculation.  The timing pulley has a pitch of .375, 10 grooves and a belt width of .5. Attached are some photos.

If there is anyone who can help me out it would be greatly appreciated. I really want to get this machine up and running. 

Thanks so much for your time.
