Solved Robo3D won't respond/home

I've had my printer for a couple of years, been working well until this morning. I did the usual turn on, connect to Repetier, Home, but it won't Home. I've plugged and unplugged the usb, turned everything one and off, rebooted the computer etc. Nothing. Worked fine yesterday, today nothing.

Thanks.

 

Does it move at all or is it just sitting there?

 

It's just sitting there, no movement. It shows '1 Command Waiting' at the top.

How do I export the terminal log?

Thanks.

 

Have you tried another slicer just to rule that out? Do you have an LCD?

 

Thanks very much for the suggestions, I rebooted, unplugged, etc. and it started working again.

Cheer.
