What do you mean by proper gantry squaring?
Both Mach3 and UCCNC have a good working gantry squaring routine. At homing both axes will move together until one axis will reach the home sensor, then that axis will stop and the other will continue until it will also reach its home sensor. After this, both axes will move back off the sensors and the homing/squaring is finished..
I think it is also possible , with a macro, to add an offset distance between the sensors if it is difficult to adjust the sensors distance for the gantry squaring.
