Brian, thanks for your reply.
As far as what is slow, i think mach 3 just runs the 2 different tap files at differenr speeds, this is in simulation mode.
I created one file in sheetcam, the other in Lazycam. The sheetcam tap file runs very quickly on simulation mode. I think this is just from the post processor in sheetcam vs the default post processor in Lazycam. Of coarse, I could be wrong. Remember, that I am new to these programs and without knowing the proper procedures it is hard to know what is really happening. I will wait for the videos and documentation to come out.
Thanks for your time.
