The top metal strip shocks me every time i touch it. Is this a plug issue? Should it not be in a regular outlet? Is it my table? Or is it my machine?

The experience you’ve described indicates a build-up of static electricity or an issue with the wiring to which your Glowforge is connected. Please make sure that your wiring is properly grounded and that it meets your local electrical code.
