Thanks for your reply.
Yes, twice was an exaggeration, however it takes longer than intended because of that.
Another problem that it causes is that the grinding wheel gets consumed only on one side of the radius, and not both.
I don't need anything special, just the same wizard that is already in mach3, but with no return after each roughing pass and that works with both sides of the wheel (one pass left to right/ the another one right to left and so on).
If someone is willing to help, even at a price, it would be much appreciated!
Thanks.
