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.

droftarts

@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.

Ian

Michael Hathaway

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.

Michael Hathaway

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?

Ian

Michael Hathaway

@droftarts Hello, I do not have anything plugged into those headers. I am thankful all of you are working hard to help me on this. I was going to wait to share what I have found until I can confirm.

So far I have printed multiple prints which have all failed.

Before I go further, I want to add that I am printing high temperature PA66 CF in the 330C range. I have a custom built E3D copper/titanium air cooled head unit I created with dual fan 10.2cfm heat break cooling. Pt1000/50w cartridge all Slice engineering. Printing at these temperatures is a common daily practice.

After multiple prints failed, I installed a new pt1000. Result: print failed with an "emergency shutdown" listed in console.

Removed SDcard and installed new card with cloned programing. While heating hotend, I received a heat fault due to not heating fast enough. I found this interesting because the identical config was used with no heat fault before, only the sdcard was changed.

Ran M303 H1 S350 tuning, compared the results which changed and added to config.g. For safety measure, I ran for both the hotend and the bed.

For my next print, I changed out spools to lower temperature Nylon which is now at 280°C instead of 330°C.

Ran a small print which was successful. 1st in two weeks of struggling.

I am currently testing more prints at this lower temperature and then I will reload my expensive material back on to test. I have been working day and night and I will keep you updated with what I find.

@phaedrux said in Duet mini 5+ freezes and shuts off heaters:

Yes, all electrically grounded to an earth ground.

Michael Hathaway

Additional fail, just now.

Only this time, the heaters did not shut off. Printer just frozen in place.
