I have started having issues with slow toolpath calculations and simulations. It takes several minutes for a toolpath to calculate and then when I run a simulation it is almost like the tool is starting and stopping. About 20 minutes to finish the simulation on a small ( 6"X6") relief. This is even happening on old job files that I have already run and were fine. I ran a job last week and everything was fine. All my other programs are working fine.
I have removed ArtCam and reinstalled it and loaded the latest Nvidia Quadro FX4500 drivers. I am running ArtCam version 7 on a Dell Precision 490 with dual monitors. Anybody have an idea of what is going on?
