Squaring with 2 limit switches on axis with only one balls screw

i have a 3040EZ Chinese desktop router-a very common gantry style “desktop” router. i’m trying to align its square to the square of an lcd display (this is to drill pcb’s that have been imagined and etched via sla method). if i’m understanding correctly this is normally done using two limit switches on ganged axis machines (2 ballscrews and motors on each side of the table-both with it’s own limit switch) where adjusting the placement of the limit switch on one side and making sure the motors stay energized to maintain position is how one aligns/squares the machine.

however i only have a single ballscrew for the Y-axis that runs down the center under the bed. can i still use the same method to align my machine? i imagine this will cause some wear to the machine, but when i think about it the same would be the case for ganged axis as well?

am i right in thinking it should still work? manual adjustment of this particular machine to change its alignment does not seem very possible or recommended given it’s construction - i feel i’m likely to cause more problems in the long run. is there a better way to achieve my goal?
