Quoted from DeejayDara:That's what Stern have suggested is the problem. I tightened it. Still triggering from vibration. The T-Rex head has also shit the bed now. Ball goes in, mouth closes and ball doesn't come out. They suggest I remove the head and tighten that opto also. Correct me if I'm wrong, as this is my first NIB machine (and only my second ever machine) but shouldn't they be responsible for having a technician fix these issues? I have no idea how to remove the T-Rex head and don't feel comfortable taking apart a machine that's a week old and potentially messing it up even more.
Good luck!
