1509 Error: Printer is no longer printing

I have the UP300 and have been very happy with the machine.

Yesterday I had USB connection issues but was able to run a long print overnight.
Today, more connection issues so I switched to wifi. I was able to run a 2 hour print. Now I’m getting Error 1509: Printer is not longer printing, when the printer tries to start a new print, when the axis first moves.
I also sometimes receive Error: 1509 Nozzle temp too low when it first tries to start printing. At this point I cannot get a print started.

Anyone have this issue?
