deleting my crap IR probe and going back to end switches
-
Any one?

you may want to revise your topic title - it reads like a statement, not a question.
and its generally bad form to bump your own thread the same day you started it (though, the title isn't very likely to attract people looking for problems to solve..)

Are you saying there is more than 1 endstop switch for z?

the part that i am confused about is how to i differentiate between the switches on the M558?
I'm confused about that statement as well. Are you using endstop switches or a probe? Endstop switches won't have anything to do with M558. And if it's a probe, there's only one.
Maybe take another run at trying to tell us what you're trying to accomplish.

@Phaedrux yes, i have a robo 3d, and there are 2 switches on the x gantry for the z end stops.
Its been done before i just don't see how the end stop switches are added into the config
When my printer originally homed, it would use the nozzle as a probe and lower the z axis until one of the nc z endstop switches would trigger.
I believe that they were set up in series so that when either was tripped the ramps board would know that the z was at the bed.All of the information i have read say that each z stepper should have its own endstop and now that they're controlled individually one by z, and the other by e. What i can't figure out is how to enter the second (e1) into the config.
If i just specify the z endstop and the nozzle is at the right side of the print bed. It would make it very hard for the z endstop to trip when the e1 endstop is right there.
I also understand that i should be able to set it up in mode 4 so that the machine will use the endstop switches as a digital switch.

Ok, that helps me understand what you're trying to do.
Are the switches actually wired in series or are they separate switches?
Are you using RRF2 or 3?
It's possible to use multiple switches on an axis, but it's a bit different on how it's done depending on the firmware. In RRF2 you need to split the Z axis into two separate axis (Z and U) and home each of them. In RRF3 it's more automatic.

@Phaedrux well just reading up on rrf3 it would make more sense just to upgrade to that.
I believe right now im using 2.05.1.
I will try and find the rrf3 duet files tonight and upgrade and try to work my way through that.

@bearer of course i realized this once you said that... i was just kind of over trying to get this probe to work.
super frustrating!

i have a ROBO 3d R1 that i had modified to use an ir sensor, how ever the one i have just isnt working as it should be
A side question, have you considered using another kind of Z probe? For example BLTouch?
Z probes have a few advantages over end stops. For example ability to do bed mesh leveling.

@zapta i have considered it, how ever with my current set up and how the x carriage is built i cant really put a bl touch on to it because theres just no where to mount it.
once i get this dialed in i am considering re designing my x carriage and re printing something that will allow me to go with a bl or something of the sort.
