OK so I’ve threatened a video for a while so if you want to be bored for 8 mins and 37 secs then here you go. And yes I know my name isn’t Fred Bloggs but don’t tell Youtube
I used inspire and downloaded the STL from the web, selected all paths (Ctrl-a) and just selected vcarve and then vbit, speed etc. Should be the same in estclam. If your carvings are inverted then add another circle to the outside of the workpiece so select the outer circle and choose offset to add another circle, odd I know but it works.
