It worked with EMC1, it should work the same way with EMC2. I made a thing that looks like a cylindrical square, but has a female R-8 taper in it. I set it on my surface plate and used a height gauge to read the total height of the cutting edge. I picked one tool as a "master" and calculated the length of all other tools relative to the master one. I could then enter this difference in length for all tools other than the master, which was set to zero. Using the master tool, I could do a touch-off on the workpiece. Switching to other tools and applying the length offset worked very well.
See http://pico-systems.com/preset.html for a couple pics. I haven't done this in a while, as having no ATC, it is much simpler to do all work with one tool, passing all workpieces through the fixture, then change tools and perform work on all parts with that tool.
