Executing Tool changes when moving to the next operation

How does MM allow for a tool change when it moves to the next operation?

My project has 2 operations. Operation 1 uses a V-bit and operation 2 uses an End-Mill.

When I ran the Job, it ran through both operations without pausing to change tools.

you need to add a tool change in custom g code , it will depend on your machine as to how it is written

this is mine

M0 is the normal command for pause but it wouldnt work for me MM video on you tube shows to use @P
