This assumes you have limit switches installed. All I have are rather arbitrary software settings, and there have been times when I've had to home to that zero to continue, which loses the home I did have setup. >If you're not on any limit switch, clicking "Override Limit" has no >effect (clicking it may show a check mark for a fraction of a >second). > >"Override limit" still will not allow you to move beyond the soft limits >defined in the inifile, and it will not allow gcode to execute which >moves beyond the soft limits or onto a limit switch. I see, out of consideration for the switch I assume. >If this description of Override Limit still doesn't jibe with what you >see emc doing, please give more step-by-step detail of what you are >doing and what the machine / emc / axis are doing in response. > >In emc 2.3, the override button will have several improvements that I >hope will make its function less mysterious.

I guess I'll just have to set the software limits to higher values, like either end of the travel to the total travel ability. Then it can be 'homed' anyplace it can reach.
