The LCD screen reads “Heater Error!”, which can be fixed by heating up through software. Press any button at the right hand and you’ll see the message changes on the LCD, which means the machine is ok.

 

  By default the firmware assumes there is a Heated Bed. As there is not you get the error.

Simply use the LCD screen menu and navigate as follows:

Info and Settings -> General Settings -> Change “Heat Plate” to NO
