I have been working on Heeks2 CAD/CAM software to replace HeeksCNC.
It is still a work in progress. I am trying to make it more hackable by having all the user interface written in wxPython for python3.
The functionality shouldn't be any different than HeeksCNC, but its architecture is different.
I have made a .zip file which can be downloaded and extracted on an Ubuntu 64-bit PC. ( I checked it on Ubuntu 20.04 and Ubuntu 18.04 )
I would appreciate someone trying it and help me develop it by finding problems with it.
This download includes all the binaries needed; for wxPython and for OpenCASCADE, so will work on a new install of Ubuntu.
