BLtouch, Firmware 3.0, Duet 2 and Duex 5 not working....
-
Hi *,
I'm migrating my CR10S pro v2 to a Duet2 with a Duex5 this days today is my BLTouch problem.
I generated a configuration with the generator but without luck. I tried understand the doku from the wiki but I simply do not get it. I'm sure it is me but I do not know how I could help myself, so you guys are my last hope.
I connected the BLtouch to PWM 5 on the Duex5 and the "to pins" to "Z probe" on the Duet2. (https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/)
Here is my last config: (This is my latest test state)

Still the same.
Would I need something like:

Should work without that.
You can try to swap the lines to:
M558 P9 C"^zprobe.in" H5 F120 T6000
M950 S0 C"exp.heater7" -

Let me explain the problem a bit more:
I get the error when "Home Z":
Error: Z probe already triggered at the start of probinb move"And the endstop "2" is "Triggered=Yes" in the webinterface.
The BLTouch is directly connected, no "made by me" wires between the board and the BLTouch.
Do I need the "M307 H7 A-1 C-1 D-1"? I found that in the docu, it makes no difference for now, but it is good to know anyway. And I want to make it right.

Can you please post the content of retractprobe.g and deployprobe.g?
Have you replaced them with the new ones? -

deployprope.gM280 P0 S10 ; deploy BLTouchretractprobe.g
M280 P0 S90 ; retract BLTouchHave you replaced them with the new ones?
I'm not sure, to be honest. I tried a lot of things and changed a lot back and forth. The only thing I may have changes is the "P0" in M280.One more thing: The BLTouch deployes and retracts the probe a couple of time when I power on the board. The status in the gui is at that point "triggered". So I think that board do not recognize the actual state of the probe.
Btw: The red LED next to the "E6 heater" connector on the Duex is "on". Should that be the case?

@Chriss
The Duex inverts the signal.
You have 2 options...M950 S0 C"!exp.heater7"
or
M950 S0 C"duex.pwm5" -

I think that should be fine, my E2 ( I think) LED on my Duex5 turns on once I start probing with my BLTouch

or
M950 S0 C"duex.pwm5"These should work for you - I use "duex.pwm1" as I plug my BLtouch into that header

Thanks for your your help, it is working now!
The change to "pwm5" did it.I use only M558 and M950 now:
M558 P9 C"^zprobe.in" H5 F120 T6000 M950 S0 C"duex.pwm5"I removed the "M307 H7 A-1 C-1 D-1" and left the "deployprope.g" and "retractprobe.g" untouched.
Wow... what a journey.

I was a bit to optimistic, the status of the endstop is "Triggered = no" now. So far so good. But the state change is not recognized. The motors do not stop when the probe got triggered and the state of the endstop do not change in the web-gui.
My understanding is that this should make that:
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 low end on Y via pin ystop M574 Z1 S2 ; configure Z-probe endstop for low end on ZWhat did I miss?

Double check your white wire for continuity. Check the crimp.
What version of BLtouch is it?
Please post your current config.g after all your changes.
-
Does the pin deploy and retract when you send M401 and M402 ?
AFAIR it's normal for the probe to show as triggered when the pin is retracted.

It works electrically, I see the status change in the web ui, this should not be the case if it is not connected, am I right?
What version of BLtouch is it?
3.1

@Chriss Morning. What is in your deploy/retractprobe.g please.
This is my deployprobe.g

@Chriss The only thing I can see that would possibly make a difference is your M574, i do not have a M574 Z1.... I have a V3 on my RailCore
This is mine
;Endstop Configuration M574 X1 S1 P"xstop" ; _RRF3 M574 Y1 S1 P"ystop" ; _RRF3 -
I removed the line for the PBTouch as you mentioned. The status of the "Endstop 2 is now "n/a". And the motors still do not stop. The BLTouch blink when I trigger it manually. That seems like the wrong direction.
I spended the last hour with some more test and I'm getting more and more confused.
It seems like it is working now. The motors do stop now when I touch the probe to simulate the bed. I do not understand WHY that is now the case. One theory is that I need to touch the "bed" if Z is below the point where it was when I pres "HOME Z". O other theory is that I needed to restart the board a couple of times.Both sounds a bit like witchcraft.... that is most strange. Anyway, I will go no to my backyard and sacrifice a goad, just to make sure that I will not loose that status any more.
Thanks for your patience guys! Keep your fingers crossed that I do not have to reopen this thread!
And to my future me: This is how it works now:
