@eman74
the second correct code mode I was meant to write is
; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y2 S1 P"ystop" ; configure active-high endstop for high end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
Hi all, I'm having some hard time with my CoreXY printer which is finally working and able to print but my Y axis is flipped and I discovered the reason:
my homing (config working with Y flipped) is on the backword left, which is not compatible with standard slicers config where X1-Y1 are located to the bottom Left:

M574 Y1 S1 P"ystop" ; configure active-high endstop for high end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
Now looking at documentations and forum to get my Y-Min (Y1) positioned on my front left should be pretty easy by modifying my M574 command for Y endstop as following:
; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for high end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
Except for the fact that my duet wont accept that and when I try to home the Y axis does nothing other than messaging "G28 Error: Failed to enable endstops" and "G28 Error: homing failed"
The hardware and electronic part works perfectly, in fact I can print and home consistently with my old config which has Y axis flipped.
Does anyone knows if I'm missing something?
@Phaedrux too late... I inverted them and (believe me I don't know why cause white is connected to the green) but finally it does home!!!!
it works... I'd like to thank you and this fantastic community of very kind and helpful 3D printing lovers and professionals
@Phaedrux yes if you look at posted pictures the white cable is connected to the duet wifi probe connector as green cable. Basically the white is on the GND and the black is on the probe.
Should I invert them?
@DIY-O-Sphere yes it does, I also looked at other troubleshooting and bypassed all cabling connecting the bltouch directly with short cables and the behaviour is the same:
but when I try to home or to manually trigger the bltouch start to blink red
all this test were done with two original BLTouch v3.1 one of them was connected to an already perfectly working cartesian printer
@DIY-O-Sphere sure, here it is:

@droftarts Thank you very much Ian, at the moment I can finally see the bltouch running a full self test at printer startup which is a huge improvement finally.
When I send M401 the pin is deployed and when I send M402 the pin is retracted but when I try to home as soon as the pin retracts the bltouch starts blinking and the bed keep rising towards my hotend (trying triggering manually the bltouch to avoid the hotend digging in my bed)
here is my homez.g:

I completely deleted the config-override and my config.g for z is:

M558 P9 C"^zprobe.in" H5 F120 T6000 ; BLTouch connected to Z probe IN pin, free up MOD pin
G31 P25 X28 Y-61 Z0.0 ; BLTouch set offset
M557 X50:350 Y50:350 S50 ; define mesh grid
is there any additional option I can use to improve probing... like adding something on the zprobe.in or similar? Any idea of what can it be? (I'll keep looking for all possible solutions in the meantime)
@droftarts my english is probably not good enough, that's also on mr, unfortunately no matter what config I used till now at the startup nothing happens, sometimes I so the bltouch starting blinking (as if the deploy test was failing).
With a tester I made sure all signals were proper directly from the BlTouch connection up to the other end, so no swapped wires. On top of that I can tell you that wires on the probe (Black correspond to black on the BLTouch and Green correspond to white on the BLTouch) and on the servo (Blue is Brown, Red is Red and yellow is green on the BLTouch)
I quitted buying non original things long time ago I'm starting to suspect all this mess is cause of the F.... duex clone... anyway I'll redo all pin crimping, just in case.
I tried using only 5V and GND with and without Z Probe with all available M950 (just in case... with no luck)
Now I'm not the kind of person which leave things unresolved so I started looking around the DUEX (cause I felt the problem was there...). Now I don't know if this happens also on the original DUEX but the clone do not provide power to the PWM...
...wait for it...
...rolling the drums....
unless you remember to put the jumper on the 5V AUX Jumper select...
so.. now it works perfectly with the proper config:
M950 S0 C"duex.pwm5" ; create servo/gpio 0 on pwm5 on Duex5
M558 P9 C"^zprobe.in" H5 F120 T6000 ; BLTouch connected to Z probe IN pin, free up MOD pin
IT WORKSSSS!!!!
Thank you all for the help, Grazie, Merci.
@dc42 I just retried it but it doesn't work, it doesn't even try to blink when I launch the M401.
It's so frustrating, my other duet wifi on the cartesian works sweetly.
can I try using some PWM on the duet wifi to make the bltouch work? (just thinking to use the duex5 only for motors and 12v fans up until I'll buy an original one)
I'm deeply sorry, I did not saw your previous question, and if any additional config file is needed please let me know.

All original only duex5 I think is not (I don't recall if I bought the original one it was long ago, the rest is all original 100%), the original cable provided was too short, I just replaced it.
regarding the M401 when I launch it the BLTouch starts to blink.
when nothing is wired I can see a red 1000 on z-probe, when all is wired the value is 0.
I changed the config so many times that my SD cards started to fail, I just replaced it with a 32Gb one.
I removed the M307 from the override file on the H7 but keeps doing it, I'll proceed disabling all M307 and give it a try.
My wiring it's still not perfect, and it's my first ever build... but here's the picture (I tried to hide the flat cable which cover the rest):
do I need to remove the M307 here? that's the only thing I saw somewhere in the docs but I'm not sure.

sorry guys yesterday I was out, I tried both with:
M950 S0 C"!exp.heater7"
and
M950 S0 C"duex.pwm5"
they don't work for me.
I looked to all troubleshooting documents and tried using the config tool, here are

M280 P0 S90 ; retract BLTouch
some pictures of my wiring:
I also tried using both 5V logic and 3.3V logic from the jumper, when I issue the M401 the BLTouch(3.1) starts blinking but does not deploy, I tried also using another BLTouch(3.1) already working on my cartesian printer but it has the same behaviour.
All wiring signals are tested and double-checked with a tester.
I'm starting to think if there is a way to connect the BLTouch all on the main board, just in case my duex has something wrong.
I'm in the middle of a BLTouch nightmare... and I keep banging my head over it...
My BLTouch is original latest version 3.1
I updated to RRF 3 (lost a lot of time to get all axis and endstop working but all seems good a part from the BLTouch)
here is my config.g related (deployprobe and retracct are standard..):
'''
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
M558 P9 C"^zprobe.in" H5 F100 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin

G31 P25 X28 Y-61 Z0 ; BLTouch set offset
M557 X50:350 Y50:350 S50 ; define mesh grid
'''
My Troubleshooting:
Double-checked wiring and tested connectivity with a tester;
verified jumper presence on duex 5
verified led on heater7 is switched on when I start the system
replaced BLTouch with another perfectly working on my cartesian printer with duet wifi and the behaviour is the same erroneous one, it does lights on and blink red without passing the switch-on test
tried other heaters on the duex with same result...
NOTE: I have 3 Z motors configured and working on Drive 5:6:7 (M584 X0 Y1 Z5:6:7 E3)
Any help would be really appreciated I followed all documents but somewhere something is just not right and I know it shouldn't be a huge thing cause I tried with another surely working one and it does the same thing so it's a config matter somewhere...
@Phaedrux I just tried but it prevents me from posting new topics... it seems the same issue there was this morning...
@Phaedrux sure it's a duet wifi with a duex5 I'm going to start a thread thank you

can you please share your config? this can help me too
@droftarts I just got tired of banging my head and followed steps to upgrade to 3.2.2 ...wish me luck...
@droftarts I actually followed all your recommendations, with no luck.
I'm a bit struggling here cause I double-checked the wiring, my bltouch is latst version and should support both 3.3v and 5v, I configured jumper for 3.3 logic and I'm using PWM5 but I cannot get the pin to deploy.
I'll keep trying but I'm starting to think I should upgrade to RRF3 to get better results...
