Connect a Lerdge Power Monitoring Module to the Duet Wifi v1.04?
I have bought a Duet Wifi v1.04 and would like to continue using my existing Lerdge Power Monitoring module.
Can I connect a Lerdge Power Monitoring Module to the Duet Wifi v1.04?
I mean this Modul: https://www.banggood.com/Lerdge-3D-Printer-Power-Monitoring-Module-Continued-to-Play-Printing-Automatically-Put-off-p-1328145.html?admitad_uid=fad9d51316ed24ef0e20a4a7af11915c&utm_content=90289&tagtag_uid=fad9d51316ed24ef0e20a4a7af11915c&cur_warehouse=CN
Probably compatible with this https://duet3d.dozuki.com/Wiki/Power_Wiring#Section_Controlling_the_external_power_supply
But since they don't provide any documentation, or release the sources for their more than likely RepRap forked firmware I cannot say for sure. Maybe someone else has already tried?
However if it is compatible with the Duet documentation, then you need a separate 5V supply as outlined in the wiki.
Edit: would maybe look at Makerbase MKS PWC V2.0 instead, they're about equally shady but has 5v supply and signaling seems to be compatible.
Hmmmmm ... So it says: Try it.
Unfortunately, I do not really know anything about electronics and really only understand the absolute principles.
I also have the MKS PWC 2.0 here. How would you have to wire that?
Do I have to wire this as stated in the description for the MKS PWC, or do I have to pay attention to something here? The 5V voltage described in the wiki disappears when using the MKS PWC module?
Should be able to use the diagram here
S1 on PWC to PS_ON on duet. (and 5v/gnd of course)
And for the resume wire S0 to a free input on the Duet and follow
Although don't know if the 5V/0.6A provided by the MKS PWC unit is sufficient for the Duet.
This may shed some light on that:
First: You mean the Wiring from the first posting?
What mean: (and 5V/gnd ofc)?
I don't understand the "ofc"
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.
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

if your goal is:
- 24v supply on / off via gcode or dwc
- emergency stop switch
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
For powering on/off: https://duet3d.dozuki.com/Wiki/Power_Wiring and
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).
how locks your config.g now

@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.
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?
