Duet3 resets constantly after the RPI boots

  • I am having issues getting my Duet3 V0.6 and 3 exp boards to work. The Diag lights all blink in unison until the RPI boots. Then the Diag light on the main board blinks very briefly about twice a second. By using M929 I can see that the controller is resetting rapidly. I have tried: Externaly powering the RPI, swapping RPI 4 2GB for a RPI 3B+, using a fresh SD card AND the one that came with the Duet3. SSHing into the pi and apt-update and apt-upgrade. Removing the CANBUS RJ12 from the main control board.

    If anyone can offer any insight it would be greatly appreciated!

    Which firmware version are you running? If you are already running 3.0RC1, please get a M122 report. If you are running an older version, please upgrade. You can connect to the Duet via USB to check the firmware version and get the M122 report.

  • Sorry, I did not think to connect via USB for a M112!
