Duet 3 + SBC connection - no Header
-
I'm confused, is it working now with the Pi4 and external PSU, or not?
-
Sorry to confuse you.
My starting configuration was:
Pi 4 & Mean Well RS-25-5
there were Problems with the SPI connection _ "Lost connection to DUET board, board is not available (no header)"so yesterday i tried:
old Pi 3 B+ & USB Power Source (smartphone charger)
-> no problems so faryesterdays 2nd try:
Pi 4 & USB Power Source (smartphone charger)
->although no problemsso my conclusion is:
the Mean Well causes Problems. -
What is the voltage output of the meanwell supply? The pi likes just slightly above 5v
-
@phaedrux
I’ve measured 5,16V directly at the Mean Well.-> Todays bad news: (Pi4 & external USB Power source)
the 2nd print was canceled, see attached pic.
-
It's possible the problem is the pi4. Can you test longer with the Pi3 to see if it happens there too?
-
Sure, went back to the Pi 3.
I´m going to print the last failure part. -
I printed for 4h so far only one problem.
See attached picture
-
So it did lose connection with the Pi3 as well?
Same SD card in both Pis?
-
Yes it lost connection, but luckily the print went on.
Does it buffer some of the gcode?No, each Pi used another SD card.
-
Are they fast SD cards?
Were you able to go through any of the troubleshooting here?

Also enabling some detailed logging as described there may be useful to see when it drops.

Sorry for the delay, i was busy working the last days.So my config looks like:
Pi 3 B+
external power supply (MeanWell)It looked like everything is fine but on my last print i got the same error again.
here is the log:
Apr 29 18:03:49 duet3 DuetControlServer[374]: [warn] Bad header CRC32 (expected 0x2303ffca, got 0xecbd5173) Apr 29 18:03:49 duet3 DuetControlServer[374]: [warn] Note: RepRapFirmware didn't receive valid data either (code 0x00000005) -
Thanks for that error message. It's being investigated.
