Cannot run FlatCAM 8.995 with source - fixed for next version

[俊霄 余]

I was downloaded FlatCAM_beta 8.995,but I can’t run it.

In ubuntu shell,there is some err.I can’t solve it.Please help!!

“RuntimeError: Refusing to import PyQt5 because PyQt6.QtCore is already imported.“

‌

[Marius Stanciu]

Hi,

PyQt5 and PyQt6 can not coexist due of the VisPy package.
You need to uninstall PyQt5 or you need to setup an virtual environment for Python where only PyQt6 is installed.

[俊霄 余]

Another question

In windows cmd,Run with “python FlatCAM.py“ command,then nothing happend! What is wrong with it??

[Marius Stanciu]

It depends what nothing means. Have you tried to test the python installation first?

What is the output if you run:
python --version

[俊霄 余]

I had installed python 3.9 and all dependencies required by the program。

Hi,

Check the path:

C:\Users\boby jx\AppData\Roaming\FlatCAM

and post here the content in the file log.txt

Hi,There is the error message：

[Marius Stanciu]

Hi,

I think you have some leftovers from previous versions.
You need to open regedit utility and go to the following:

Computer\HKEY_CURRENT_USER\SOFTWARE\Open Source\FlatCAM

And in the key style write the value 0

‌

[Marius Stanciu]

In any case I just pushed a change that should take care of this issue.

[俊霄 余]

thanks,I have successfully run the program.

Report a BUG

In cutout. When I click on Generate Geometry button but not select any Geometry or Gerber，the programe will close without any Warning message.

‌

Report a Suggest

In cutout,I can only select 'lr', 'tb', '2lr', '2tb', 4 or 8 type of gaps.I suggest add a custom option that I can custom gaps number.

You have the manual option where you can add gaps where you want and as many as you want. In Advanced Mode.

In cutout. When I click on Generate Geometry button but not select any Geometry or Gerber，the programe will close without any Warning message.

Fixed in the latest commit. The updated Chinese translation is also added.

[俊霄 余]

There is an other BUG

There is no response from the program when use “Convert Any to Excellon” function.

The programe will close without any Warning message when use “Convert Any to Geo” function.

Hi,

Let me know what is the output in the log.txt file….

Hi 俊霄 余,

The issues with conversion are fixed.
Thank you for the reports.

Report a BUG1

In cutout.I add gaps with manual option,and I click left mouse botton,but it will crash when I try to add gaps again.

Hi 俊霄 余,

Regarding the first two bugs I would very much like to know what was that you were doing and I mean the exact steps and the shape of the geometry you were using. In any case I think I solved both issues in the latest commit.

Regarding the 3rd reported issue, it is not a bug. Simply said, the matplotlib package that is behind the 2D Legacy graphic mode does not support currently PyQt6. Until they make a new release to support PyQt6, this mode is not functional.

[俊霄 余]

In BUG1

1.Add a grb file.

2.In cutout function,click “Generate Manual Geometry“

4.click “Manual“ button,click “Manual Add Bridge Gaps“,add gaps where I want,click left mouse button.

5.click “Manual Add Bridge Gaps“,add gaps where I want.

6.Programe will shutdown.

‌

In BUG2

1.Select Geometry that cutout Generated.

2.click “Convert Multi to SingleGeo“.

3.Programe will shutdown.

[Marius Stanciu]

Hi,

New BUG

If I select two of Geometry Item and click “Edit Object“ , program will shutdown without any Warning message.

Can you please send me the project with those 2 geometries that when selected together and edited it generates a crash? Thank you!
In this case the program should edit only the last selected geometry object in the selection.

This program GUI has some diffrance between windows and ubuntu,like HUD text,plot area.In ubuntu ,look great than windows.

I have no control on how the program is rendered on different OS’s. Yet, I know that the HUD had some issues and I’ve updated the app in the latest commit such that the HUD rectangle is now updated in real time depending on the length of the coordinates text.

[Marius Stanciu]

This is how it looks in Windows 10:

‌

[俊霄 余]

In this case,you can try select whatever gbr file and use “Convert Any to Geo“ twice and select both of them and use “Edit Object“,it will reproduce the problem.

‌

[俊霄 余]

Why my GUI display like this in latest version:

‌

[Marius Stanciu]

What is the scaling value that you use in Windows Display Settings? What kind of display (resolution) do you use? A 4K one?
I can test on 2k and HD monitors and all is Ok in those.

[Marius Stanciu]

I guess your HUD font in Preferences was set too high and the app did not took into consideration the font size set in Preferences but the default one. Most likely the issue was because in Windows you changed the HUD font size.
Fixed in the latest commit.

[俊霄 余]

My resolution is 3K(surface pro 7),scaling value =175%.

It's still the same in the new version

[Marius Stanciu]

What is the size of the HUD font set in Preferences → General → App Settings → Font Size → HUD?
Try to set it at most at 20 points.

[俊霄 余]

‌

[Marius Stanciu]

Hi,

Change the HUD font size to 10. It looks like you have old values, leftovers from other versions.

[俊霄 余]

Report another BUG

In “Milling“,If I choose Excellon, then click “Generate CNCJob object“,progrme will do nothing!

[Marius Stanciu]

Hi,

In “Milling“,If I choose Excellon, then click “Generate CNCJob object“,progrme will do nothing!

This is not a bug, it is OK. This section functionality is not implemented at the moment only the GUI has been put in place to allow the future functionality. For milling holes use the Utility button in the Excellon Properties Tab.

[俊霄 余]

I would like to know how to package the program as an installation file or ask you to release the installation package so that it can be installed on other Windows computers. Although it is unstable beta, I think it is good enough and I would like to recommend it to my friends who do not know how to configure Python modules.

[Marius Stanciu]

Right now the Units changing is broken. Tools Database is broken. Excellon Milling is not implemented. The Geometry object data structure still needs to be checked in all parts of the program. Most likely many of the Tcl commands are broken.

[俊霄 余]

can not run with new version(marius_stanciu-flatcam_beta-1d1613d2d662),I can’t find qdarktheme package!

It’s a new dependency that is needed. Do:
pip install pyqtdarktheme
