I think it is mechanical as even though there wasn't any intentional changes I had the belts off as I cleaned out the printer, the bars and extruder.

I verified screws seem good, belts seem good, operation seems as smooth as it has been before, so not sure were I caused this issue yet.

Thanks for your reply.

One quick thought is to see where the belt tensioners on each side belt are, they should be in the middle of the belt and line up with the gantry when it is half way from the back to the front as you look down.
