hey folks, in trying to figure out how to use Run From Here i may have changed something with my safe z set up in config settings. now when i use the button to go to toolchange position, the z axis goes all the way up and trips the limit switch causing the machine to just freeze until reset. both of my machine are doing this and i realized today that it does the same thing by pressing the button to send it to the zero position too...what did i do? i am using mach 3 version R3.043.0453 with windows 7 and very old pcs(offline)- that will actually be for another discussion soon. thanks in advance,dan
