    Is there any way to swap the z and y and use y and extruder with endstop to auto level z and manually adjust y on mini Rambo

    If you just want to have dual endstops on Z, then you don’t have to swap anything, just enable DUAL_Z_MOTORS and DUAL_Z_ENDSTOPS in Configuration_adv.h. That’s for homing to Zmin. If you need to home to Zmax, then there’s a little more to it.

    Oh, and you have to disable the E0, by moving it’s pins to something else and then make a dummy E1 with the pins from E0.

    that’s what I thought I was confused on how the stepper driver was able to stop output to one motor while still powering the other being as there is only one driver and 2 outputs so z y  and x can all essentially home to the min as the home im just tired of squaring it all up before each cut

    Right. There are actually two features here. Dual motor gives each motor it’s own driver. But that’s not necessary. Dual endstops only does one thing, and that is allow the motors to move independently when they are homing so they each hit their stop exactly. Dual endstops only works if there are dual motors.

    But the mini rambo has only 4 drivers. You can only do that on one axis.

    I’m confused the z axis is series to 1 connector how AR the motors being limited wouldn’t you have to separate the z to independently stop each motor

    Yes. You can, with some work, connect one Z motor to the E0 port. Then attach separate endstops.
