I received a lovely new Ender-3 for Christmas. Put it all together. printed a few things. All was well. I was very pleased.

All was fine so I moved the printer to what would be its new home and left it for a day or so. Came back to it, turned it on, clicked auto-home and ... nothing ... then 'auto home failed printer halted' appeared on the screen. I thought I must have dislodged something so checked all connections. All were good. Still the problem occurred.

What is happening? Where should I look next? Is there any way to view a system log? Does the printer need to be returned?

Help would be appreciated.
