So been working on some round boxes & been noticing the pattern to the 3D Roughing algorithm. It tends to follow a Contour/Raster pattern which makes sense for large areas to hog out. But for channels that are just a little bit wider then the bit diameter it tends to waste a lot of time due to all the material being cleared out by the Contour path - there’s nothing for the Raster pattern to do. However, then at some depth it will change the pattern to Raster/Contour which doesn’t seem to make any sense.
Anyway, just wanted to suggest optimizations for the 3D Roughing so it would remain consistent & maybe not do Raster passes that it doesn’t need to - they take quite a bit of extra time compared to a Contour pass that cleans everything out.
Here’s a link to a video of what I was seeing(this is while it’s doing Contour/Raster pattern) :
