Author: PeterS242

State: open

Getting the following errors during the "Exporting GCODE file..." phase.

```
Use of uninitialized value in subtraction (-) at Slic3r/lib/Slic3r/Geometry.pm line 109.
Can't call method "isa" on an undefined value at Slic3r/lib/Slic3r/Point.pm line 12.
```

Command-line being used:

```
./slic3r.pl --fill-pattern concentric
```

All settings are default.

Some models that will (or are large enough to) produce the error are as follows.
