Door Open Switch and LED´s

[Martin1454]

Which kind of LED's are you using? It it is a LED strip that runs the same voltage as your PSU (12/24V?) then connect it to a spare FAN connector and use the FAN speed to control the brightness

[deckingman]

@cr3d M582 is really just to check the state of a trigger which is defined using M581. So the easiest way to configure a door switch is to connect it to a spare end stop input, then use M581.

As for your LED lights, under what condition do you want to turn them on or off? If it's simply manually at any time, then the obvious answer is to fit a simple on/off switch.

Curious to see how you activate the LED, I chose to make them as a thermostat controlled fan output, enabling whenever bed of hotend is over ambient temperature.

M106 P1 S1 I0 F500 H0:1 T25 Basic thermostatic control for FAN1 either heater over 25C lights on.

But I would like to make it so LEDs turn on whenever motors are active as well as when the temperature is high.

[CR3D]

Thank you for your answers

@Martin1454 yes the LED Stripes work with 24V

Normally my setup is following:

The Duet is the controller board and the raspberry touch with repetier server is the HMI.
In repetier server, there is a function Light on/off.

In Repetier Firmware there is the command M355 S1 / S0 for this function.

But I will test your solutions

@bearer i like your idea with the temperature control

Just out of curiosity, is that a "because I can" kind of thing or is there some practical reason?

Printer is fully enclosed with relatively small windows so it gets relatively dark inside; temperature controlled works well enough when printing but for moving the axis when cold it would be nice to have light as well, and automatic is "always" better than manual:)

[deckingman]

@bearer We'll just have to agree to differ on the "automatic is always better than manual" thing. I just use an on/off switch.....

However, in your case how about putting your M106 command in your slicer start gcode rather than config.g? That way, the lights would stay off until you start a print and the temperature gets above ambient. Or maybe, just use a couple of macros - one to turn them on and one to turn them off. Then you could call these from the slicer start and end gcodes as well as at any other time. Just a thought........

[A Former User]

Possibly getting a little OT, but if I can keep the config isolated to the Duet and not the slicer thats a + in my book. Sometimes I do remote operations using a IP camera as well, so automagic or at least controllable is good for me.

I'm sure I'll come up with a better plan once I'm more familiar with the Duet and the firmware, but temperature control was quick, easy and 90% good enough, if need be I can heat the bed to 25C in seconds.

[deckingman]

@bearer Fair comments. Just bear in mind that almost all gcodes can be input at any time - even "on the fly". Sometimes that can useful....

[CR3D]

Hi all,

thanks again for your answers!

I want to show you the working results.

I connected the LED´s directly to the fan output and implemented the firmware like this:

For the Open Door Switch I want to use M581. In principle it works...the macro is called, but for me M226 doesn´t work...

I have to complete... i use a Raspberry Pi with repetier server as User Interface. The connection is USB.
So I have read a lot about USB and Pause...for example this

https://forum.duet3d.com/topic/8065/m226-pause-gcode-ignored/12

I also updated to the last firmware version...

My Pause gets ignored... how to fix it?

Thank you a lot!!!

[dc42]

M226 is for use within the GCode file being executed, for example where you want to pause at a particular point to change filament, or insert an object to be embedded within the print. Elsewhere, use M25. [M25 should also work where you are supposed to use M226.]

[CR3D]

Ok thank you...and both work with USB connection from Raspberry?

[dc42]

M25 will work. M226 should only be used from within an SD card print.

[CR3D]

Ok Thanks! I will test it ...

I did something similar by sniffing the serial communication of the Panel Due with a small Arduino board and controlling RGB LEDs colors based on the status, temp, etc. There is a recent thread about it here, with pictures and a link to the source files.

[CR3D]

Unfortunately, M25 does not work with a print via USB. See error message

any recommendations?

New Firmware Version

@cr3d said in Door Open Switch and LED´s:

That's as expected. The headline description of M25 is "Pause SD print". When printing over USB (which we don't recommend anyway), the program that sends the data has to handle pausing. That's what Octoprint and similar programs do.

[CR3D]

Yes I know... repetier Server is something like octoprint.
And I know that you don´t recommend it...

I have to use this as my user interface, because my customers want this.... is there no other possibility to control the pause?

I spoke with the guys from repetier, they said that it was possible to request a break.
RequestPause: Reason

The server also understands @Pause
Is it possible to send such commands to the server?

The same problem exists for me with the filament runoutsensor...

Would be glad if you can help me!

Please clarify: what inputs does Repetier Server have for requesting a break?

What is it that your customers don't like about using Duet Web Control as the main user interface?

[CR3D]

So now here is the answer from Roland Littwin .. the programmer of Repetier... The answer in the picture is in german... here the translation from the mail:

---

<response type="requestPause" string="true">//\saction:pause\b\s(.)</response>
<response type="continuePause">//\saction:resume\b</response>

Recently there was a discussion with the Marlin developers and Gina from Octoprint to correctly implement the official solution. As a result, you can
// action: break
send from the firmware to tell the host to pause. (RequestPause: The reason is the solution only Repetier host / server understand, therefore, if it is officially implemented better you use action commands.)
// action: resume
would make the host talk again.
This was wrong in older server versions because the description was too spongy. But with the last version it should work correctly. Marlin is still echoing: before that what is accepted by the server.
So if the sensors are connected to the printer you have to bring the firmware only to send this. How does David know who wrote the firmware? Logic would then perhaps if sd pressure as always else host ask for break. Whether he also installs a continue or if you should always explicitly click on the server afterwards is then a matter of taste.
Hope that helps to solve it on the firmware side.

In my opinion, a break function is enough. that would continue in my opinion then synonymous over the server suffice.
Is it possible to add this command ... ?

Thanks a lot!!!

And about Duet interface:

I try to use it more in the future, but companies often like a clear and simple design, file management on the server, display of files etc ... actually things that are less related to printing, but unfortunately it is. ...
