I went through most of the tutorial videos for Estlcam this afternoon and I am very impressed. Trochoidal toolpaths, thread milling, 3D milling, cutting open vectors, . . .So much so that I've downloaded the demo software which is fully functional for a limited period.

It seems to offer much more than Vectric Cut2d for a quarter of the price. Only drawback is does not show a picture of the final cut part, just the toolpaths.
