I just tried these two additions to my .ini file, then restarted emc while the machine was within about a thou of zero on all axises. But on the restart, the home flag wasn't set where it was restarted, and a click on the 'home all' button then zeroed the display in addition to setting the home * on in the selected sequence. This then throws my machine off by however much it is from zero, and this is not at all nice, forcing me to repeat the homing by electrical contact detection that I am currently using as I get setup to 'etch' a couple pcb's. That takes 5 to 10 minutes of creeping along at .015/minute feed rates for all 3 axises to arrive at where it was when I shut it down. It would be nice if there was a setting that would cause it to set the home stars, _without_ zeroing the counters, accepting that it is 'homed' wherever it is at. Is this even possible Jon?
