Its good to know there is a satisfied user out there.I have a feeling there will be occasional requests for your stash of relevant data for years to come.I'm a little surprised that the circular transition from one part of the cut to the next came as a shock to you as this has been the common way to do it for some time,it means the machine continues cutting on the optimised trajectory instead of halting at the end of a straight move and then beginning a new move.In other words it removes a deceleration and subsequent acceleration phase from two moves as well as permitting a slightly shorter distance to be covered.It might not matter for a handful of one off items but if you had a couple of thousand items to cut,we might be looking at a saving of a few days.
