Issues when generating excellion cnc job object

[Bnjamn]

Hello,

First of all, thank you for keeping this Flatcam project up to date !

I tried it recently but I got this error when I try to make a cnc job object on an excellion file :

"Couldn't build proto file into descriptor pool: Invalid default '0.5' for field operations_research.sat.SatParameters.clause_cleanup_ratio of type 1"

It seems to be related to "ortools" or "protobuf".
I cannot find a way to fix it :-(

I run the program on Ubuntu 22.04 with python 3.10.12
ortools version is : 9.11.4210
protobuf version is : 5.26.1

Any help would be welcome !

Cheers,
Benjamin.

I just found a workaround by uninstalling ortools.
Not sure if it is okay to work without it ?

I saw in the "requirements.txt" file that ortools is optional.
