Path regression: Missing output operations

[Gauthier]

Oh! Great gurus of Path development!

Im troubled by the last milling Path I made from FreeCAD...
In the final output, it miss the "Fixture op" and the "1st tool operation" (I have only one tool in my job).
They are not send to the post processor!?!?
So, the G5X (coordinate system selection) and the spindle start order are missing in the final GCode file.
During the last real machining that I carried out in February, it still worked...

When it worked fine:

Code: Select all

N100 (Exported by FreeCAD)
N110 (Post Processor: grbl_post)
N120 (Output Time:2020-01-28 17:55:00.041375)
N130 (Begin preamble)
N140 G17 G90
N150 G21
N160 (Begin operation: Fixture)
N170 (Path: Fixture)
N180 G54
N190 G0 Z5.000
N200 (Finish operation: Fixture)
N210 (Begin operation: T2: Fraise D3x7)
N220 (Path: T2: Fraise D3x7)
N230 (T2: Fraise D3x7)
N240 (Begin toolchange)
N250 (M6 T2.0)
N260 M3 S12000.0
N270 (Finish operation: T2: Fraise D3x7)
N280 (Begin operation: Profile_Faces)
N290 (Path: Profile_Faces)
N300 (Profile_Faces)
N310 (Compensated Tool Path. Diameter: 3.0)
N320 G0 Z5.000
(...)

Now, the lines from 160 to 270 are missing.
Should I do open a bug ?

Thanks for your work and your replies,

Hi all,

This is the same problem than this one:
https://forum.freecadweb.org/viewtopic.php?f=15&t=44681

As I have good knowledge of the Grbl post-pro, I will try to correct it...
