The problem I solved. there is a option called "tool dispaly". I cancle the check mark on it, and regenerated toolpath, the computer done perfectly. But how comes my teach did not know that option....

Thank you for your replying. but you know what, this situation happens in the lab of my college. There are almost 50computers sit here. mastercam autocad and inventor are installed in these computer. So I think it's not a computer hardware issue. Anyway, if you find something please tell me BTY, I have a Cam test next week, my CAM teacher told us that be very careful when setting up depth cuts because the computer will play with itself and out of your contorl. If you set 10+ levels for z depth, just xxxx of computer and do it again. Do you think it's a nice way to learn mastercam? Thanks

hi, roger I am thinking about one possibility. Maybe, educational version can not creat toolpath very quickly， the tool must touch each path level because its not a real mastercam for commercial purpose?

the situation happened in the lab of my school. There are 50 computer which installed mastercam X3. parameters of toolpath display during creation are not special. Is there any possibility such as educational version can not creat toolpath very quickly， the tool must touch each path level because its not a commercial version?

in other way, there is something diferent in "toolpath display during creation"

does anybody who study in the school meet same situation like me? is there any possibility due to educational edition mastercam?

hi guys. I am doing some exercises in my college's lab with mastercam X3. There is a problem I met. When I finished setting up several parameters for my toolpath, then press ok, I have to take long time to wait mastercam finish its preview toolpath creation. The tool will go through every path carefully which I set up. If I set 10 levels for Z depth cutting, I have to wait 10minutes and see the tool touch every level. So, you can image that, if I make a mistake like set 100 levels for cutting a stuff, the only thing I　can do is shut down my computer because during the computer working, any menu is locked up. do you have any same experience with that? How can I change it? I saw another guy play with mastercam in his laptop. After he set up toolpath, the computer will creat preview toolpath at a very short time and automatically. I am so confuse about that. I hope someone could help me out. Thanks a lot
