Dual Z motor Homing with dual switches

LeonMF

I've got a Promega from M3D running a Duet Maestro controller.

I've completely redesigned the Z axis motion system and now have dual Z lead screws. I know that, as of 1.19 I can use the z-probe to auto level but I'd like to treat this similar to a gantry axis on a CNC where there is a limit switch per axis.

As a result, I've attempted to use the method outlined here:
https://betrue3d.dk/duet-wifieth-use-m584-to-autolevel-or-sync-z-axis-using-2-or-more-motors/

It mostly works but I need to stop the axis that hits it's limit first and let the second axis continue. until it hits its limit switch. Is this possible without having to perform separate axis commands and deliberately twisting my bed a bit?

Never mind. It works. It helps to have the correct limit switch assigned to the correct motor!
