V2XT Y axis drift

[Spin]

Hello,

What could be the cause of an axis to drift?
I was drilling a 2.5 in deep hole manually on a V2XT and I notice when I backed up the drill bit to remove chips the drill was off center on the Y axis but the readout was displaying the correct position.
I then re position the axis to the correct location and finished the hole.
The same thing happened on the second hole.

Has anyone dealt with this issue?

Thanks

It may be a loose encoder coupling to the motor, the teeth worn off the Y axis drive belt, a loose taper lock, etc. Try a feedrate to the next hole instead of a rapid move.

I will check for this things.
Could it also be a poor power souce?
