how I got FlatCAM 8.1 working on OS X [a long time ago — see comment thread for lots of good tips from others!]

install_flatcam.sh

brew update
brew install pyqt geos spatialindex
easy_install pip
pip install virtualenv

cd Development/Others\'/
mkdir FlatCAM
cd FlatCAM
virtualenv env
source env/bin/activate
pip install numpy matplotlib rtree scipy shapely simplejson
# copy contents of FlatCAM_8.1.zip into FlatCAM folder
python FlatCAM.py

After that I get the error ModuleNotFoundError: No module named 'ezdxf.math.vector'

This was fixed on the Beta branch in this commit

I'm currently in the process of getting FlatCAM build with MacPorts.

I finally got it all working, but it will still take some time until I got all newly created port files for flatcams dependencies into shape to get them into the upstream macports repo.

One thing I wanted to share here, though: The problem with

AttributeError: module 'vispy.visuals.markers' has no attribute '_marker_dict' error

is due to a "patch" in appGui/VisPyPatches.py, which has long been available in upstream VisPy. So lines 16-34 in this file can safely be removed and then flatcam also runs with newer (i.e., > 0.9.0) vispy versions.

anyone know about this error ?

I presume you are trying to run flatcam with python 3.12, because FileFinder.find_module, which has been deprecated since python 3.4 and removed in 3.12 (see https://docs.python.org/3.11/library/importlib.html#importlib.abc.PathEntryFinder.find_module).

So you can either switch to python < 3.12 or try to fix that line by using load_spec instead.

Did someone manage to pack flatcam in a standalone app with py2app or pyInstaller? I'm trying to get flatcam work on my Mac (OSX 16.x) but I have no luck. I tried with different python versions but had no luck. I would super grateful if someone could compile flatcam to a standalone application. There is also an icon in .icns format I made from the png logo. Feel free to contact me, I'll share it with you.

Has anyone fixed this? the original code line is module = loader.find_module(name).load_module(name)
i've changed to module = loader.find_spec(name).create_module(name) but it triggers the ModuleSpec Object has no attribute 'create_module'

It likes the find_spec change but not the create_module one

On the off-chance people don't know this:

brew tap tomoyanonymous/flatcam
brew install flatcam-beta

Help me###

i've installed beta successfully, but after import gerber file, there is nothing on plot area even properties record the board dimension

brew tap tomoyanonymous/flatcam
brew install flatcam-beta

This ^^^^

I did manage to get it working manually under Sequoia using previous instructions, but had a lot of crashes. Terminal was showing a lot of package related errors.

Then I saw thomergil's comment and installed under hombrew.

Works like a charm.

Thanks @thomergil and of course big thanks to @tomoyanonymous

@DeeEmm glad it helped. I stopped using FlatCam. Too buggy and crashy. Depending on what you're trying to do... https://github.com/thomergil/pcb-nomad3

I'm just returning to it to try and overcome some quality issues with making PCBs using my laser.

Burning the mask by converting a raster image in lightburn is not great quality as the image is broken up into scan lines which appear as aliasing in the track outlines. So I figured I'd try using an isolation milling toolpath instead. The only issue is that EasyEDA does not export milling tool paths so I need to convert the gerbers using something like flatcam. I did look at pcb2gcode but I'm on a mac, so options are somewhat limited.

I run pcb2gcode on a Mac. 👍🏻
