I use the 2010 Screenset for Mach3 and it has ToolChange position as well as many other features built in. Took me a bit to get it all figured out and dialed in but it is a huge timesaver now. For cuts that require multiple tools, it will go to the tool change location, wait for me to change the tool, move to a static probe location, probe Z, and start cutting. Rinse and repeat for all the tools.
