I haven’t used mye shapeoko for a while, and when I started it up I got prompted to update drivers on my mac.
I did that, and now I have problems with the machine.
It might be a coincidence that it happened now. It might be a hardware problem (I have moved the shapeoko since last using it ).
Does anyone recognize this?
Thanks! 
And before anyone asks. Yes, I have checked the belts. One was a bit loose, and I tightened it.
The picture was taken after the tightening. 
Looks like the x axis has some slop in it. Is it possible the x axis sprocket set screw is loose allowing for some free play?
Backlash — please check the pulley set screws: http://docs.carbide3d.com/shapeoko-faq/shapeoko-3-how-to-check-the-pulley-set-screws/
Thank you thank you thank you both!
That fixed it.
