It sounds like your machine may have been bumped pretty hard during shipment. Please contact us directly (by e-mail or our contact form) so that we can ask some follow-up questions, and see how extensive the issue is. (There may be a simple adjustment that you can do yourself, or we may need to send you replacement parts.)
For the moment, I’d recommend disconnecting your servo motor cable, so that you don’t stress the motor until the mechanical issue is resolved.
