Import Dxf as Geometry Object on Linux Fedora doesn't display anything - fixed for next version

[max xam]

Hi Marius,

I have checked the Gui preferences Edit Color:

but the object selected it’s not showed on linux Fedora:

if I make a remote connection from Mac to Fedora using vnc I can see correctly:

Do you have any idea for the issue ?

If I open gerber and excellon everything it’s correct:

Hi Marius,

on the same object from Gui executing cncjob the following error:

Hi,
Attach here the Geometry object and I will look at it when there is time.

Hello,

The DXF file you attached is opening without issues with the latest commit of FlatCAM Evo (beta).
Can you share the cncjob TclCommand with the parameters that you have used and which used gave you errors?

Thanks,
Marius

[max xam]

Hello Marius,

I don’t use TclCommand, from the Gui interface I import the dxf like geometry object and after I use the Milling procedure with preprocessor GRBL_laser:

Hi Max,
The issue with not creating CNCJob objects due of the changes I made last evening, should be fixed now.

As for why plotting doesn’t work in Linux or MacOS that’s beyond me, it’s a thing of drivers or upstream bugs. You should check in that case the 2D Graphic Engine in Preferences. It’s a low performance mode but at least you should see if it works this way.

[max xam]

Where are located 2D Graphic Engine, I dont' found it in Preferences, which tab ?

[Marius Stanciu]

‌

[max xam]

Ok thanks, it fixed the problem the object has been processed with cncjob correctly

Hello Max,

I'm in a remote area in the mountains without my notebook so I will see what can be done next week.

Best regards,

Marius

[max xam]

Hello Marius,

it’s ok, after when you have time if you can explain me the funcion Paint.

Have a nice week end.

Max

[Marius Stanciu]

BTW, have you updated to the latest commit? It looks like you are using an older commit…

[max xam]

Yes, maybe I forgot to update Mac with marius_stanciu-flatcam_beta-88d9d6aeb48c.zip, now it’s working.

[Koon Wong]

I noticed one difference in the ParseDXF.py the very first line, the one without “Point” DXF does not import DXF with the circle or round drill shape.

from shapely.geometry import LineString, Point

‌

[Marius Stanciu]

Hi @Koon Wong ,

DXF does not import DXF with the circle or round drill shape.

You should create a separate “issue” where you can share the file that cannot be loaded.

[Koon Wong]

The file can not be loaded is “riferimento_x100-100.DXF” at the beginning of this issue. Commit Fix .dxf import:

https://bitbucket.org/jpcgt/flatcam/commits/2e3590182fb18f2794b53c82fd57d2e7ce5afe44

I found a Windows complied version here http://217.129.211.236/eagle/ but your site have only source code for Ver 8.994.

Now I got it working with my WinPython so I have access to the code to test. For any issue I will create it, thank for the great work, and I can also compare the result with CopperCam gcode to Mach3/Mach4.

‌

[Marius Stanciu]

Hi @Koon Wong ,

I apologize for the confusion. If you look on the Downloads section of this repository you will see some text files that hold inside the download link. The reason for this is because uploads of large files fails on Bitbucket and I had to use this solution.

More than that. I upload code to the Beta branch only when I feel that I reached a stable point in my working copy. My actual work is kept elsewhere:
https://bitbucket.org/marius_stanciu/flatcam_beta/branch/Beta_8.995
and this issue refer to that work.
Almost all the bugs fixes that I personally solved since the last release (8.994) are only in my working copy.

I know that is confusing , and those issues should be open on that repository, I hope that soon we will clear this mixup.
The reported bug in this issue is solved in my working copy.

Hello Marius,

long time I don’t contact you.

I have a new issue.

After importing a dxf like Geometry Object, I used Geometry editor to delete some parts not interesting, after exiting from editorit ask to me to save but it really don’t save.

Hi Max,

We need to dig deeper about this. What version of Flatcam are you using? Can you share the DXF file and tell what you deleted?

‌

[max xam]

  <div class="preview-container wiki-content"><!-- loaded via ajax --></div>
  <div class="mask"></div>
</div>

</div> </form>

[max xam]

The selected parts (in red) must remain, all the other parts (in blue ) must be deleted.

The installed version is : marius_stanciu-flatcam_beta-43fd141b8e2e.zip

[Marius Stanciu]

Hello Max,

Please use the latest version if you are going to use what I am working on. Meaning this: https://bitbucket.org/marius_stanciu/flatcam_beta/get/Beta_8.995.zip

With this I have no problem in deleting parts of a Geometry while in the Geometry Editor.

‌

[max xam]

I cannot run the last version:

Traceback (most recent call last):
File "/Users/max/flatcam95/FlatCAM.py", line 8, in <module>
from appMain import App
File "/Users/max/flatcam95/appMain.py", line 85, in <module>

File "/Users/max/flatcam95/appGUI/MainGUI.py", line 44, in <module>
import darkdetect
ModuleNotFoundError: No module named 'darkdetect'

‌

I try with:

Successfully installed pip-22.1
(flt) max@macMax:~$ pip install darktheme
ERROR: Could not find a version that satisfies the requirement darktheme (from versions: none)
ERROR: No matching distribution found for darktheme

‌

[Marius Stanciu]

Always look in the requirements.txt file for any packages that are required.
You need to install: pyqtdarktheme and darkdetect

pip install darkdetect pyqtdarktheme

‌

[max xam]

Now it’s working great !

Many thanks

[Marius Stanciu]

With welcome!
But Max, try not to resurrect old threads like this, if you have issues it is best to open a new one. This way we can keep track of things.
