Im switching my shop from the old "touch off to the top of the part" to a more accurate touch off point.
Most of my machines are Mitsubishi control which will ignore any fixture offset Z value, thus giving you a consistent tool length every time. My two fanuc controls however will add (or subtract) whatever you have set for G54 Z. So if I touch off a drill to the table during setup I get say z-14.800, but as soon as I add in my fixture offset and touch off the same tool I get z-17.800, which will obviously crash.
So my question is, other than why is fanuc the absolute worst, is which parameter do I need to change in order to stop that from happening. The tool length should be the tool length regardless of anything else happening in the machine.
Fanuc iO-MC circa 2006 maybe.
