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:
- Open up the STL-file in the Slic3r software.
- 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.
