post a high resolution picture of your board
Post some photos we may be able to see a failed component.

I connect the 5V PSU directly to the board. I checked the wiring twice. I also tried to use a USB PSU. Same result...
I used this guide:
https://duet3d.dozuki.com/Wiki/Power_Wiring#:~:text=The Duet operates on two power circuits: a,or not an external power supply is attached).Did you connect the PS_ON pin of the Duet to anything, or leave it not connected?

@dc42
I leave it unconnected. -

Yes the LED lit continuously. The 24V PSU is a MeanWell RSP-500-24. The 5V on is a MeanWell RS-15-5. When I use the internal switching regulator the error message disappears. Is the 15W PSU too weak to power the board?
can you confirm the board works as expected when using the internal regulator like you reported above? Please try with your 5V supply disconnected, the 24V supply connected and send M122
Thanks
-
just to make sure. when put the jumper on the external 5v supply pins, you removed the jumper from the internal 5v supply pins?
-
Yes, without the 5V PSU the board works just fine and I am sure that i use the right jumper configuration(s).

When i switch from the 24V to the 5V supply quickly (just change the jumper position while it is running) i don t get any error message.
Edit:
If i turn on the 24V PSU first and after some seconds the 5V PSU everything will work fine.

@Luk14 If its working fine using the internal 5V regulator then we need to work out why the external 5V supply is causing the issue. Please can you measure the voltage level between 5V and Ground on (e.g.) the PanelDue header using a multimeter to confirm that when the external 5V PSU is attached the Duet has 5V on its 5V rail (not just on the power supply input).

PSU: 5,00V
pin1/2: 4,65VI increased the voltage to (5,44V/5,05V) but the error message still occours.
-
@luk14, just to be clear: when do you see this error message? Is it:
- Just once when you apply external 5V power, when VIN power is not already applied;
- Just once when you apply external 5V power, when VIN power is already applied;
- More than once; and if so, when?
-
Nr.1 and when i apply 5V and VIN simultaneously.
-
Any further ideas?
-
We're not sure what is going on. I've tried to replicate the issue by applying USB power, connecting with DWC, and then applying 24V power, but this didn't cause the fault. I had the internal regulator still enabled, but this shouldn't make any difference given that 5V power was already provided via USB.
So I suggest we try replacing your Duet. Please contact your supplier to request a replacement under warranty, referring them to this post as authorisation.
I'm sorry it has taken so long to reach a decision about this.
-
I got a replacement two days ago. With the new board everything works like i expected.
One more question. My 24V PSU can be turned on and off by a external signal. I wired it up and it works, but unfortunately the PSU is not a ATX one and turns off if it gets the 5V signal from the Duet. Is there a setting in the firmware where i can invert the ATX_ON pin?
-
-
Ok it seams like there is no firmware solution. I will use a relay instead. But there should be a simple firmware solution, because these Meanwell PSUs are quite popular.
