# OctoPrint Unable to Connect to Lulzbot Mini

We have a Lulzbot Mini at my office (i.e. it's not my personal printer). It's connected to an OctoPi and I've been able to get just one file to print on it (which I had to cancel due to leveling issues). Others have used it successfully in the past.

However, right now, every time I try to connect to it through OctoPrint, I just get gibberish back:

The only thing I can think of right now is refreshing the firmware, but before I do that, I figured I'd ask here. Does any one know what this gibberish is and how I can restore this printer to regular operation?
