Strange noise on the TAZ 5

Hello,
After leveling the X axis following the lulzbot suggested procedure I started hearing a strange grinding sound when the printer is moving diagonal.
This sound increases along with the speed. When the printer is moving only in the X or Y axis everything seems normal.
If I try to move ithe head and the bed in jog mode (even for more than 200mm) it doesn’t make any strange noise.

Any suggestion?
Thank you in advance
