Duet mini 5+ freezes and shuts off heaters

Michael Hathaway

This one is directly after freeze

@michael-hathaway said in Duet mini 5+ freezes and shuts off heaters:

Last reset 00:03:26 ago, cause: reset button

this is the reason for the "freezes". now its just understanding why this is happening.
Might be a good idea to post a high res picture of the reset button area

Michael Hathaway

@jay_s_uk So the reset button on the board is being triggered?

jay_s_uk

@michael-hathaway yep

Is there anyway of resetting besides pressing that button?

jay_s_uk

@michael-hathaway i suppose the question is when and where did you purchase?
one for @Phaedrux or maybe @droftarts

not that i'm aware of

Michael Hathaway

My old board just started doing this recently after 1.5 years use. And my new board does the same exact thing. I purchased from Filastruder 1.5 years ago.

@michael-hathaway I just did a quick test on my Mini 5+ to see what a power cycle, M999 (reset) and reset button press reports on restart in M122.
M999:

I did the M999 first, and that is what the subsequent M122 'Last software reset...' is reporting. I notice that your M122 also reports the same time for 'Last software reset...' so I don't think the reset is coming from the firmware or gcode file.

I think if the firmware is reporting a reset button press, it probably actually is a reset button press or short. Is the printed case you have the Duet in new? My guess is that, as the board heats up, it's flexing slightly and somehow shorting out on the case. Maybe add some nylon washers under your mounting screws (ideally the board should be mounted using nylon washers), to lift the board up a little?

@droftarts Thank you, I will try that. I will also order a new board just in case I have fried this one.

@michael-hathaway Looking at the Mini 5+ schematic (https://raw.githubusercontent.com/Duet3D/Duet3-Mini5plus/main/v1.01/Duet3_5%2B_Wifi_schematic_v1.01.pdf), there are also reset pins on the 12864_EXP2 connector, SWD connector (just behind the reset button, but as it is unpopulated with a header, this shouldn't be a problem) and there's also a test point (on the back of the board, by the SWD connector pins, I think). I don't think you have anything plugged into the 12864 connector, but again check that it is not shorting out to anything, top or bottom.

I ordered a new Duet mini 5 plus board with overnight postage, should have it tomorrow. I also ordered nylon washers as recommended.

This time when mounting in the petg enclosure, I will allow to board to float and not be fastened down so well.

I have found new Samsung endurance sdcards, which are designed to be powered on continuously. I am hopeful this increases reliability.

I appreciate everyone's help I have received and I will update with my progress as I proceed.

Brand new Duet mini 5+ board, mounted loose on nylon washers.

Reset tripped, frozen mid print.

I have 3 boards now that do the same thing. One board ran great for 1.5 years and this happened.

droftarts

@michael-hathaway is it the same print, same Gcode file and stopping in the exact same place? I still don’t think anything else would cause M122 to report a manual reset except for a reset button press, or short on on of the other reset pins I mentioned in my earlier post.

Did you change anything just before this started happening? I can’t think that you’d have three Duets that have the same problem!

Ian

Michael Hathaway

@droftarts I didn't change anything else. I will try a few different prints and report back. I don't know the electronics well enough to know what would trigger a reset other than the button and those contacts which are not being touched. If a stepper was getting too hot, would that trigger a reset? Would a broken wire trigger a reset?

Phaedrux

Static build up maybe? Is the frame grounded? Is the PSU - side grounded to earth?

droftarts

@michael-hathaway do you have anything connected to the 12864 EXP2 header? Like a 12864 screen?
