The issue is most likely that the temperature was not set to 0 when preparing the print file in the Slic3r software. To fix this do the following:

  1. Open up the STL-file in the Slic3r software.
  2. Under the “Filament Settings” tab, check that:
  • The extrusion temperature is set to 0 for both first layer and other layers.
  • The bed temperature is set to 0 for both first layer and other layers.
