My CAM software is outputting a g-code of M6 T1 for tool changes within my program.  I think this is really messing me up because I don't have a toolchanger so when I put a new bit in the spindle it throws my coordinates off.

How can I set up Mach3 to go to do something like this when a M6 T1 is called: turn off the spindle, go to a preset position in absolute machine coordinates, then let me put in a new bit, let me move around with the keyboard to go to a new z-zero, and then let me set a new z-zero (only, not x & y), and then let me move the spindle somewhere safe to start, and then let me continue with the program so that it doesn't forget where it's local coordinate system is?

Option in General Config, Stop Spindle and Wait for Start.
Your G Code will have to move you to your toolchange position if that is what you want.

The other option would be to choose Auto Tool Changer, if you use that then you will have to write your M6Start macro to do as you want.
