Trung,
Good to hear.
Just to provide and example of some Simulators that can show stock correctly.
Predator CNC Editor V9 is one for example, however you have to specify a number of lines with X/Y/Z and A values, the shapes that you want the stock to look like. This program at the time it was available was another cost you would not need to pay.
Today to do the task you would need to purchase Predator Virtual CNC V11 and that is very expensive, also other Simulator programs that are out there are not cheap, some of which are $2k.
So with madCAM Joakim has produced a good alternative that now provides a very good output in Simulation and is part of one program. I am sure more refinements are to come.
Also a thing to remember madCAM is a CPU resource engine program rather then a GPU one.
At present the madCAM program can access up to 8 Core, an improvement would be to have say 12 or 18 Cores to speed up the process depending on what CPU processor users have.
Regards,
Mauri.
