I put a print on yesterday evening, and left it running for a while - it looked to be ok when I left. When I came in this afternoon there was a horrible mess on the print bed. Thanks to whoever stopped the print at 38% done.
I'm guessing this was caused by the low temperature in the main space, but it would be good if someone else could look over the printer before we try to use it again.
I'll investigate getting a new cover.
