We are openly discussing slicer issues with commercial software like Simplify3D, so I'd like to see more folders for CAD-CAM software like Fusion360 ( free of charge for hobbyists ) even when they are closed source.
Like VDX said, ignoring the "real world" isolates the RepRap idea until we see only hardcore users here.
As long as we make it clear that we are not the official source of support for those - providing a link to the right place if available - I have no problem with discussions of commercial products related to reprap and fabrication.
Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.
