FlatCAM-on-MacOS

How to make FlatCAM (V8.994) work on MacOS (12.7.6)

Download the sources from:

https://bitbucket.org/jpcgt/flatcam/downloads/

originally from:

https://github.com/larroy/flatCAM?tab=readme-ov-file

First install python3.8 (higher than 3.11 doesn’t work)

brew install [email protected]

Then install PyQt-5 (other versions don’t work)

brew install PyQt@5

Then install all other FlatCAM dependencies with

python3.8 -m pip install -r requirements.txt

Then change the versions of vispy and shapely

pip3.8 uninstall vispy pip3.8 install vispy==0.7

pip3.8 uninstall shapely pip3.8 install shapely==1.7.0

Then change some code … :

For Error: “No module named 'ezdxf.math.vector’ ” in v8.994 BETA

In “appParsers/ParseDXF.py”

OLD: from ezdxf.math.vector import Vector as ezdxf_vector

Change to NEW: try: from ezdxf.math.vector import Vector as ezdxf_vector except ImportError: from ezdxf.math import Vec3 as ezdxf_vector

For Error no “Inf in numpy”

In files “appTools/ToolPaint” and “appTools/ToolCutOut” and “appTools/ToolDblSided” and “appObjects/ObjectCollection“

OLD: from numpy import Inf

Change to NEW: from numpy import inf as Inf

Then run it with

python3.8 FlatCAM.py

Or better even - create an Automator script (Run Shell Script):

“Shell: /bin/bash” “Pass input: to stdin”
