The gcode you need is G28. This takes the machine to s predefined position, which could be your tool change position. You set the position (using machine coordinates) in one of the Mach3 configuration screens, although I can't remember which one off the top of my head. As m_c says, you can then incorporate this code into your M6start macro so that as part of the tool change operation, the machine will go to the tool change position. On my machine, I also have a fixed touch plate set into the bed at this point so I can do a "second operation" tool height setting without having to jog the tool again. When you hit "run" the M6end macro is called which by default takes the machine back to where it was when the m6 tool change started.

Can you explain exactly what you are trying to do? Everyone has their own way of working and I'm not quite sure what you're looking for.
For example, my tool change code moves the tool to tool change position, waits until I hit Run, then goes back to where it started and carries on. While the tool is at the tool change position, I can choose to use one of the tool-height setting options I have written or not - they are not built-in to the tool-change macros themselves. That suits the way I work, but might not be right for everyone.

Neale,
When I'm running our GCODE to produce one of our units it had four cuts in total. I would like it to go to a certain position WHEN a tool change it needed then I press auto tool zero it hits my wireless probe (Which will be in a fixed location) zero's its self out and then returns to the next cutting position.
Hope this makes sense to you! :D

Anything to do with toolchanges happens, or at least starts and ends in the M6 macros.
I'm not entirely sure, but I think once you've used M6start to move to your toolchange position, you can then use your tool zero button, then once you're finished and click cycle start again, M6end takes care of moving back to the work area.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
