Help w/ Diagnosis!

Howdy! I have lots of noise and vibration in my y axis movement. Can i please get some help diagnosing?

Notes:

OG model x-carve with dewalt 611.

Noise is a recent phenomenon.

It is localized to the nearest side (in the video).

The machine still carves but has developed a few errant cuts here and there. I assume this will get worse.

Thanks in advance!

It looks like only your left Y motor is working and pulling the other side along.

Check your wiring first.
