X + Y NoT HoMiNg - Z is a BL Touch & IT IS Homing????!!!!!!!

[Pickett]

undefinedAs the title of this post states the Z is a BL/3D Touch and it is in fact homing on command. However, the X & Y are not in fact homing regardless of my attempts to home said Axis????? When I do hit the command button "Home All" all of the axis will move simultaneously though they will ALL only move a couple two or three MM's, never make contact with any of their respective endstops, and then they will declare themselves "Homed?????" So what gives what is up with this here odd homing behavior???? Why will ALL of the axis move on the Home All command yet only move a mm or two maybe three IDK all I do know is that they never make contact with their respective endstop yet they will declare themselves "homed" when obviously they are not???? Please tell me I am not crazy and please I hope someone has a solution. I want things to work with RRF though Im already contemplating/considering moving over to Klipper coz it has been one issue after another with this RRF though Ill be perfectly honest the vast majority of the issues Ive encountered have been/are due to inexperience with RRF. All of my 3d hardware & fw experience is with the BTT SKR lineup particularly their SKR 1.4 Turbo of which I used to believe was "the board to get" that is until I learned of Duet3d and their "g code is everything" Philosophy along with ALL of the safety measures they bake into the hardware. I was settled on Duet3d and still am I just need to get past this hump of dealing with the "non homing/not hitting endstops/overall not working so great hump that I am on top of right now so anyways....... Okay that is all Ive got below you will find the applicable files that I am aware of thus far:

In accordance with the Testing Endstops publication from Duet3d the following m119 command was done when only the Duet 3 Mini 5+ was powered via USB coming from its SBC, a RPi 4b with only the D3M5+ being connected via USB:

10/8/2021, 9:32:10 PM m119 -- Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: not stopped

BTW the previous m119 command is NOT true as in the X and Y are not pressed up against their applicable endstops.......

Lemme know guys and gals any help would be appreciated very much so as it is this is the only issue that I can tell as of right now that is holding me back from finally and I do mean FINALLY getting a print started and completed on this very much custom Anycubic Chiron!!!!!!!!!! Thanks!!!!!!!

You didn’t post your config.g or response to M115 (to show what board and firmware version you’re using), but most likely you need to invert the logic of the X and Y endstops. See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Microswitch

We recommend you use the normally-closed contacts of the microswitches, which are generally the outside two connections on the microswitch, and set the signal polarity to active high (S1) in the M574 command. If for any reason you use normally-open microswitch contacts, then if you use RepRapFirmware 1.x or 2.x then you will need to set the signal polarity to active low (S0) in the M574 command, and if you are using RepRapFirmware 3 then you will need to use S1 but invert the polarity by putting a ! character at the start of the pin name in the M574 command.

@pickett It harder to help with multiple threads being opened for the same issue:

https://forum.duet3d.com/topic/25374/all-axes-will-home-but-have-not-connected-any-endstops/24

I have locked the previous thread we can continue here.

Where we left off you had determined that you originally had your endstops wired as Normally Open, and the firmware configured for them to be normally closed. It looks like they are still wired Normally open if the M119 command is saying they are triggered when they are not. For now try changing the lines in config.g to the following:

M574 X1 S1 P"!io5.in" ; configure active-high endstop for low end on X via pin io5.in
M574 Y1 S1 P"!io6.in" ; configure active-high endstop for low end on Y via pin io6.in

Then test with M119:
Send M119 with the endstops not pressed. note the results
Press the X endstop and while its pressed, send M119, note the results
Press the Y endstop and while its pressed, send M119, note the results.

post those three M199 outputs here.

@t3p3tony I didnt change or do anything with the X just yet as I had only wired the endstop up on the microswitch to the outer most wiring like the instructional said to. I apologize I know I stated last night or there abouts that I was certain that I had it wired correctly welp I guess I was wrong as I had the wires connected to the 2nd and 3rd "pins" of the micro switch when it should have been 1st and 3rd and left the 2nd alone. That was what I had just done to the Y microswitch and sure enough I started seeing results in its output whereas before no matter if I compressed the micro switch or not no change of status of any sort was noticed. Now I am seeing results. So anyways this last entry at 0456 am was when I had the microswitch compressed. THe entry before that was uncompressed and of course before that is the M119 results......

Y: low end switch connected to pin !io6.in
Z: low end Z probe

@pickett ok so with the switches wired as you have them, if you are seeing M119 changing when you press the switches then tou can include the "!" or not in the M574 definition to make the logic correct.
