[CorvusOculum]

Version

Version 2.3.55.2

Operating system type + version

Windows 10 Pro 64bit Ver 2004 OS Build 19041.630

3D printer brand / version + firmware version (if known)

Modified CR-10 S4 runing Duet Boards and RepRap firmware version 3.1.1 Stable

Behavior

1. Calibration menu >> Filament Flow Calibration
2. Click the "Generate 10% intervals..." Button
3. Generates the five test objects and slices, but it creates a duplicate centred at 0,0,0 and throws an error "Toolpath outside the print area"

4. Switching back to the 3d Editor view, the duplicate object at 0,0,0 vanishes. (See attached)

5. Simply can't create properly sliced file.

Found an other bug, maybe that's that or maybe not, but with the fix it's okay.
problem was when brim_width < brim_offset
