Gcode export very slow

[herbk]

Hi
since a few Versions ( i don't remember since wich) Path needs very long to export a gcode file.

If i export this milling path with FC 0.19.17512 (a well working release i keep) it needs a few secounds (may be about 10).

If i export it with one of the newer AppImages the export need more then 5 Minutes.

The last version i try'd with:

OS: openSUSE Leap 15.1 (KDE//usr/share/xsessions/plasma5)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.19443 (Git) AppImage
Build type: Release
Branch: master
Hash: 74680b8a15ad37e53eee0d341e95cd32631d88a3
Python version: 3.8.1
Qt version: 5.12.5
Coin version: 4.0.0
OCC version: 7.4.0
Locale: German/Germany (de_DE)

But it's the same with the last releases before

Can you upload a file for reference with a preferably simple model?

Today evening, i'm at work atm...

OK, had time to create a liite example:

To export the Job to a gcode file FC 0.19.17512 needs less 2 secounds, FC 0.19.19443 needs 71 secounds.

Yesterday i'v had to export the milling path for the parts at the pic above (Adaptive- and Contour Ops, Contour OPs with Ramp Entry and Holding Tag Dressup). This needs not much less one hour from clicking the export button to the shown gcode...

If i use the Pocket OP instead of Adaptive the export works much faster at newer Appimages to (less 3 sec with this example at the 0.19.19433) but still longer as at FC 0.19.17512-

If I suppress the display of the code with --no-show-editor it works again in seconds.

I'm having the same problem; frustratingly slow. @chrisb: how do you invoke that argument?

- Edit Job, either during creation or doubleclick an existing
- select Output tab
- enter the parameter in the "Arguments" field.

@chrisb: Thank you! Went from an hour or more to a few seconds!

I was impressed by the time gain myself, even more so, as each editor can display it in seconds as well. I guess it's a Qt thing, where the FreeCAD developers can do probably nothing.

Hi Chris,

I was impressed by the time gain myself, even more so, as each editor can display it in seconds as well. I guess it's a Qt thing, where the FreeCAD developers can do probably nothing.

why this should be a QT thing, if one FC works fast and an other slow? Both FC versions at the same machine of course.
