Duet 3 + SBC connection - no Header

Nobu

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.
