Z homing is endstop switch. It seems to me that regardless of everything, that if I go to the G code console in DWC and send a G1 S1 X-300 command that my X should go to the endstop, but it doesn't. As soon as I send that command, it immediately shows the X being at Home position.Yes, I've been wondering about those Z probe definitions and whether I need to comment them out. I've just had the Z endstop so far, but will be receiving the mini ir probe tomorrow and hope to implement it ASAP.

You need to use M119 to make sure the endstops are working as expected.
-
M119 shows;Endstops - X: at min stop, Y: at min stop, Z: at min stop, Z probe: not stopped. My print head is currently near the center of the bed and Z is about 10mm from nozzle.

You have your endstops inverted. If they are simple microswitches, rewire them to use the two outer connections on each switch (the normally closed contacts). Otherwise, change S1 to S0 in the M574 command in config.g. See https://duet3d.com/wiki/Connecting_endstop_switches.
Additionally, if your Y endstop is at the back of the printer then it is a max stop not a min stop, and you need to change Y1 to Y2 in your M574 command.

Endstops triggering all the time means you have the endstops wired (or configured) incorrectly as Deckingman mentioned earlier in this thread. Are they active high or active low? Do you have them wired appropriately? Does the M574 command match? You've posted two different versions of M574 in this thread, one with endstops active high, and one with them active low . Check which is correct as you have the unit wired and make M574 match.
EDIT: What DC42 said…

I wired my endstops per the Duet Wifi wiki:…...................Makerbot Mechanical Endstop v1.2
Thus is a small board holding a microswitch, LED and a few other components. Connect pin 1 of the endstop board to the 3V3 pin on the Duet endstop connector, pin 2 or 3 to Duet endstop connector GND, and pin 4 to Duet endstop connector STP......... This is wrong? My pin 1 is red wire. It's connected to the center pin on board connection. Pin 2 black wire is connected to ground on board. Far right pin on endstop, green is connected to "stop" pin of appropriate board connector. I went by this diagram[https://duet3d.com/wiki/Duet_WiFi_wiring_diagrams]…..... so I guess I need to swap out the positions of the black and green wires from how I have them? Correct? -
I'm sorry for any confusion I;ve caused anyone trying to help me. I'm new at this and sincerely appreciate the help. I've made adjustments to the M574 command and M119 now shows all endstops open(not stopped) and I still have correct movement when sending G1 S2's. X homes correctly now also. Only hurdle now is getting Y to home correctly
Once again, I sincerely appreciate everyone's help! -
If I didn't miss the things you have changed, your M574 command should be M574 X1 Y2 Z1 S1 since you have your Y endstop at the rear.
Have you changed your home scripts also? So that when you home Y it moves to a positive number towards the rear? -
As Jackal says. See the section that starts "For a machine with a homing switch at the high end, homex.g would look like this instead" at https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Homing_files but apply that method to your homey.g file. So all the X parameters in that example should be replaced by Y.

It is accomplished gentlemen! Thanks again for e-one's help, especially you dc-42. I just received your mini ir probe today. Now to get it installed. Wish me luck!

Glad you got it sorted. Don't be afraid to post here if you have any other problems. We'll all try to help if we can although when DC42 posts, it is wise to listen to whatever he says.
