Has anyone had problems with the SS and running extremely long nc files?  I try to run a long nc file and the SS will lose data at the very begining of the program. I cut the NC file in half and it is running fine.  Does anyone have any idea why this would happen? I does not happen on shorter files.

Thanks,
Tom

Really large files can give Mach fits. You can turn off the toolpath display to free up some processor resources. Also, don't try to run a file off a network drive. Brian has moved the graphics to its own thread in Mach 4 so everyone shoudl see a dramatic improvmetn with large file but it will be months before V4 is out.

Thank you Jeff, that seems to work, Looking forward to Mach 4
