Many thanks Gerry, much appreciated,
I am not planning on installing/running MeshCam until my DP 30 days are up then I can spend more time learning it.
One thing that comes to mind having made this is that the 70 x 70 tiger took 3 hours machine time - whereas a skilled woodcarver could, i think, have made this in considerably less time (and possibly even, done a much better job). Metalworking is probably where the major benefits of 3D CAM prove to be of greater advantage. So may try a metal object with MeshCam and use the mill instead of the router.
