Toolpath outside print area

[Calcousin55]

What happened?

After slicing there can be seen a toolpath outside print area was detected in gcode preview.

Project file & How to reproduce

idler_bearing_cover.zip
Using the default Voron V2 300mm3 0.4mm nozzle profile with 0.10mm layer height
Using the following settings causes toolpath error
Skirt & Brim -> Draft shield -> Enable
Infill -> Sparse -> 40% Cubic

Version

2.5.59.3

Operating system

Windows 10

Printer model

Voron V2

UPDATE: I can confirm that this issue happens only when the Sliced Preview tab is opened. If it is not opened, the gcode can be exported / uploaded. If the tab is opened it will create an error.

TLDR: do NOT open the Sliced Preview tab if this error occurs.

This happens for some models and it seems like the brim goes out of the print bed instead of being under the object.

A quick workaround I got is to change a brim setting to trigger slicing and then directly go to the Sliced Preview or Gcode Preview window instead of going directly to 3D View. You can export / upload now.

It's because if you use complete_objects and brim_per_object, the brim needs to be shifted. But it shouldn't if no complete_objects.
