To control the duet via PS-ON is nothing new.

But to do this via a smart home actuator might be a more current option.

While searching for an actuator I came across the Shelly 2.5
I have chosen it because it brings its own web interface to control. And because it's not cloud bound by default.
There is no nead for a smart home server. So it's already a good option out of the box.

The goal was to be able to switch the printer in such a way that it cannot be accidentally switched off in the middle of printing. Also all loads should be switched off.
The result is the following schematic. (Only the relevant area)

The key is to switch the actuator parallel to the PS-ON relay output.
I use an industrial relay with several channels, this has the advantage that one can switch a separated feedback channel once the duet is booted.
Currently I have 3 channels in use. Power supply, feedback and the heating bed (220V).

The following setting must be made in the switching channel of the Shelly.

Set the button type to "Detached Switch".

Set an "Auto Off" timer for that channel.
With this setting the input switch (SW) can be queried separately.

With this wiring and setting the printer only can be switched off by G-Code.
Either out of the DWC or automatic at the end of printing.
Of course, it also works via a hard-wired kill or main switch.

When everything worked I have been thinking about how to make it more comfortable and to get acoustic feedback.
The drama began seting up a homeserver starting to build a node red dashboard....
To cut a long story short it ended with the integration of G-codes, video image and the activation/deactivation logic.
Still work in progress...

@PaulHew said in Maestro, RRF3 and BLTouch issues:

M950 S0 C"^zprobe.mod" ; create servo pin 0 for BLTouch

M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin
M950 S0 C"zprobe.mod" ; servo/gpio 0 is Z probe MOD pin

That should be the right code.

That's a bug, I have already reported.
Let it set to the e1heat. You have to adjust that later on in the config.g

The probe section then should look like that

; Z-Probe
M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin
M950 S0 C"zprobe.mod" ; servo/gpio 0 is Z probe MOD pin

Configuration for Ender3
config.json

@printthatthing
Leave it as it is....
You can edit that later on in the config.g

M950 S0 C"duex.pwm5" ; create servo pin 0 for BLTouch
You have to change that to
M950 S0 C"!duex.pwm5"
or rename to
M950 S0 C"exp.heater7"

You will find the full list of heater pin names here

You can do that very easily in Prusaslicer.

@nikscha
Reduce the frequence for the ssr. (Q parameter for heater) I had the same problem.

Edit:
That is my setting
M950 H0 C"bedheat" T0 Q10

@joshuamensch
Your files are set up for heater 4, but the Bltouch is wired to heater 3?

@Demi
You have to check resume.g. There you will find the extrusion...

When would you really want to use it?

I would like to use that for adjusting values or scrolling through a file list.
For me a combination of a touch menu and an encoder is the perfect solution on small screens.

@oliof
I love the 12864 of my Maestro.

Hi Ky,
I had exactly the same issue, that was driving me crazy....
Check the Pin
"Try loosening or tightening the set screw slightly to adjust the trigger sensitivity."
There is a description how to set up the srew, but I can't find it currently.
In the end a quarter turn had reliably solved the problem.
Regards
Frank

Edit:
You can find the information in the manual

I have also been looking for a solution for some time.
Currently I am welding the spools in vacuum foil.
But how about a waste water pipe and 2 printed lids. These are available with a diameter of 250mm. You could put 2-3 spools in one container. 1m costs 15€ which should be enough for 4 containers (12 spools).
I think I will give this a try.

@crazy-pig said in Can not homey but homeall or other is OK:

G1 H2 Z2 F380
G1 H1 Y-350 F2000
G1 H2 Y55 F1280
G1 H2 Z-2 F300 ; lower Z again

Change all H2 parameter to H1

@T3P3Tony
No chance.....nor cleaning cash

@T3P3Tony
This is a momentary relay.
The secondary channel displays the status of the relay.
In the node red flow it controls the button status (color and naming) and also deactivates the boot button once the duet is up.
This is not absolutely necessary. But otherwise you can trigger the relay several times in a row. (From the Shelly's own UI that is still possible)
With a slightly modified circuit it even would work with only one channel . To me with this wiring it seemed to be more logical and the relay was lying around unused.

Edit:

(btw added .mp4 upload)

Still getting this error:

node-red-contrib-looptimer2 ---> node-red-contrib-looptimer

Edit:
"node-red-contrib-stoptimer" is missing in the description

@MintyTrebor
Just checked the flow chart.....amazing clean
I wish I could do it rudimentarily that way...

@MintyTrebor
Perfect...
I'am currently working on a flow to remote switch the printer.
Realised over a Shelly 2.5.
The Shelly only starts the boot sequence. Shutdown only is possible by sending G-Code . So it's self locking after a print is started.
That also gives the possibility to auto switch off at the end of printing.
As a beginner in node red it was a challenge to realise the logic of the buttons....They are getting active in relation to the state of the relay and the flow itself.
But I have learned a lot, even to control the duet over html....

Modified my 12864-LCD case for 30x30 yesterday.....

@seeul8er
Led me to the question if it would be possible to add a rotary switch and a reset knob?
