Your soft limit min should be the most negative number and your soft limit max should be the most positive. 0 is more positive than a negative number. 1 is more negative or less positive than 2. Turn off your soft limits and ref the machine. Look at machine coordinates and see what the axis are and write those numbers down (this should all be 0 unless you have a home off distance entered). Then jog all axis to the far position, look at machine coordinates and write those numbers down (these should all be a negative number if your homing positive). These are the numbers that will go in your softlimits min and max dros.
