I will let you know of anything else. What I have done is set the tools in the database to match what I had loaded in my tool changer, though, when I load the program I have to select the tools, & put in my material size. I have a unique CAM template in TCC, as I have a 48 x 48 section of my router as I cut my change over parts from half sheets (48" x 48") x 3/4" hdpe, so I always set my material size to that, for every program bigger or smaller. Simplifies things for me, :-) You can slow down the speed of the simulation also, down to a crawl by adjusting the dwell settings under the setup menu. You can run 4 views at the same time. Now I don't save the programs to run on my machine, I just check for collisions, & to make sure I don't have any fixture offsets wrong. A really nice feature is you can take a measurement of the geometry after the program has run, it has saved me a few times.
