Sanlee,
you can build up a series of operations, using the wizards. To do this you must save each operation separately, then cut & paste them together using notepad, or whatever text editor you use. The combined code must then be edited to remove unwanted operations, such as intermediate M30's ( program rewind ). If you need to have different tools for each operation, make sure that they are called at the start of each operation, along with the appropriate spindle speed.
This can all be done from within Mach, without leaving the program.
