Connect a Lerdge Power Monitoring Module to the Duet Wifi v1.04?

First: You mean the Wiring from the first posting?
This:

Second:
What mean: (and 5V/gnd ofc)?

I don't understand the "ofc"

And Last:
I can use this wiring for the rest:

Yeah, it has the S1 and S0 labels on the MKS PWC, they are the PS_ON output and PowerLoss input signals respectively.

CrazyCreator

Ok ... I read and hope I understand

For the rest of wiring I can use this picture too:

I know the picture is for the MKS Gen 1.4, but I mean the routing for the other cables

Hi,

if your goal is:

24v supply on / off via gcode or dwc
emergency stop switch
reset

try this:

You only need : example for a opto low-level trigger-relay

@crazycreator Duet is able to resume after a power loss, if you set it up: https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure

@thwe and @Stephen6309
My only concern is to have a 16mm button on the front of the printer, with this I want to turn on the printer.

If I can turn off the printer with this button, that would be nice, but it is not necessary. I can do that also via web interface

If anybody came accross the same thing i got a solution. now the baord turns ON with the front button.

Sidenote: it does not matter where you get the 5v from. The pins from the main extension ports are allready if use on my board (bltouch).

CrazyCreator

how locks your config.g now

ediik

@CrazyCreator it does not matter. The lerdge board simply gets 5v from the duet and stays on for the time it has 5v connected. No cdg changes necessary.

CrazyCreator

ok ... I would test it

@ediik Hi! I came across this thing. One question - why don't you use PS_ON signal for controlling Lerdge power module?

ediik

@Meltex hi sorry for late reply. i honestly dont know how to wire it up the right way.

Don’t feel bad this module has beaten me as well for time being. I went to the solid state relay setup as highlighted above and was much simpler to get going with the same button. But... I really would like to figure this out too at some point lol.

Little correction, for me, it’s the Makerbase MKS PWC V2.0 module. No matter what I tried, just couldn’t get it to work.

Hello, did anybody the Lerdge Power Modul to work with the Duet. I want to try the same thing. Have a Lerdge Power Modul laying around here. What does the PS_ON pin on the Duet exactly? Act it like a 5v on and off switch?

Richygoat

Here is no answer to this question. I want to turn the PSU off with this modul. When it get 5v continuously from the Duet it stays always on. When there is 5v, GND an PS_ON on that connector how does it exactly work. I know this is 5v in. Does the PS_ON switch the 5V to PS_ON?

Richygoat

Ok the PS_ON pin will be connected to Ground when the PSU have to be enabled. Is there a way to get a 5v Signal to shut the Relay down? See the picture attached.

Richygoat

Is something like this possible?

This is how it works perfekt. Big thanks to Eryion from Rics 3D Discord.
