The nice thing is that i have another board. Was going to down the line get a duet 5 for it since its a small printer, but it will be a small printer with a big display.

RE: Dead PanelDue 7I
An update. As I was preparing for brain surgery on this thing it has been sitting in its Anti Static bag for the last at least 48 hours.
Decided to plug it into the computer (same cable, was still plugged into the computer) and that is when i heard that lovely ba-da-bing sound. The computer recognized it and it showed up as a a Bossa port. I was able to flash it.
Currently the printer is mid print, so I cannot install it to verify that it works fully.
Either way, for anyone with a possibly similar situation, letting it sit for a while, and possibly in the anti static bag may be helpful. -
RE: Dead PanelDue 7I
I received the new PanelDue I ordered today, came up as it should have.
At least I can be certain that the Wifi board itself does not have anything going on with it that would prevent the PanelDue from doing its job. -
RE: Dead PanelDue 7I
Thank you, great ideas.
Definitely can scrounge up some old electronics around to practice on. -
RE: Dead PanelDue 7I
Ordered, will see how it goes.
Any recommendations how to go about replacing it ?
I welcome any suggestions.
I will watch some videos etc to better prepare in the meanwhile.Removal:
I would assume I want to take the PanelDue as far apart as I can, remove the screen etc.
I do have a reflow gun, after taking apart my plan is to try to heat the chip enough to remove by pushing it off to the side? I could see doing this would possibly bridge some gaps.
Or perhaps before heating try to glue something to the top to use as a lifting device ?
I do also have a "solder sucker" and a Hakko FX-888D soldering iron with many small tips.
Should I try individually going around the legs and removing as much solder as possible ?
Also have copper desoldering braid, perhaps that would be the best method before heating with reflow gun ?Install:
Hmmm, let me remove it first without collateral damage..... -
RE: Dead PanelDue 7I
Just to confirm:

Thank you

@dc42
Tried other cables, no difference.
Verified cable functionality by plugging up to an old Tom Tom, detected right away, so comms are goood.U4 is putting out 3.26 V.
CA9 does have 3.26 at the end specified.
Either end of LA2 does show 1.19 V.
Nothing is getting hot.
Replacing the Atsam looks to be within my skilset, provided I can get one and it doesnt need extra programming with tools I may not have.
Digikey shows a few in stock, not sure if they would be exact matches.

RE: Dead PanelDue 7I
Will do.
I have brand new in the box Duet Wifi for the next project, the current cable I am using came out of that box to eliminate the possibility of of a bad cable. -
RE: Dead PanelDue 7I
I suppose I could try a few more different cables, have been using the one that came with the Duet Wifi boards.
Not really sure how to fully eliminate the USB port not making contact possibility. Plugging usb in does turn on the backlight, so at least GND, and 5V are getting through.I will verify again the correct voltages later today. I was able to measure +3.3V yesterday in the spot I think you care referring to.
Did also measure 1.X voltage on a regulator, I forgot the exact number, will confirm later also.
Perhaps I described flashing incorrectly:
The backlight is on, always on, cant make it go off even with pressing erase for 1 second followed by reset.
What does, or did initially flash, is the screen itself. Every so often, I would say a 40 second average you would get a quick blip of the screen, kind of like the initial very short white illumination I normally get when powering on, just before the logo displays. Almost as if periodically the unit is trying to boot.Ironically, I had a similar situation when I initially purchased the screen, before there were any motors or much else hooked up to it. When i was just familiarizing myself with the Duet Wifi and PanelDue I had just those two hooked together.
I was using the 10 pin ribbon cable at the time. Initially I had it hooked to the correct port via the ribbon cable, it came on and life was great.
Throughout the build process at one point I powered on an the screen did not boot. I believe that I had the 10 pin ribbon cable in the wrong port. Powered down, switched to the right port, and I think all was back to normal. Hard to remember, but what I do know is that it did not always boot the screen after that. Sometimes I had to boot a number of times, and I think I am correct in saying that sometimes the screen would boot after being powered for a while. Either way, that is when I initially got familiar with the process of flashing the firmware, bossa etc.
Was able to follow the guides, usb port came up at that time just as it should have, flashed without issue, booted without issue, switched over to 4 pin wire only since ribbon wasn't long enough to reach my desired location.
I put it in its case, and haven't touched it since. Have had no issues for the last 2 months, probably powered down and booted up 30 times since then.
About 2 weeks ago I did have an issue with the screen, or entire system rather going idle during a print. Screen would show IDLE on the corner while machine was still printing.
I originally thought it was on long prints, what would happen is that the screen would essentially stop getting new information, layer number would stop updating, etc.
The machine continued on, and the prints finished as expected. I do not know if pressing the stop button on the screen would have done anything at this point.
During this time the web interface could not connect either, I believe wifi was going idle.
Reboot would fix everything.
At the same time I was also having issues with Fusion 360 taking forever to launch, so I think all of it was really an issue caused by my router. Once I powered cycled it all was better, no more disconnection issues.
Don't know if much of that is helpful or not.
I was surprised that even if it is due to the router and wifi disconnecting that the screen would stop getting information and go idle.
So maybe there were some underlying issues, perhaps from once plugging the 10 pin ribbon into the wrong port.
Once i get my new screen I will be curious to see what happens if I turn off wifi router mid print.Mike

@bearer
Yeah, based on not much more than a gut feeling I think it is going to be one of the micro controllers on the board.
-
RE: Dead PanelDue 7I
I am definitely interested.
Short of waiting for the fairy to make it all better I am out of recourses. I have been able to verify that at least one regulator is supplying 3.3 volts, there is another one furthers stepping it down to 1.something. But that's about it. -
RE: Dead PanelDue 7I
Yeah, should have known better, will know better.
Anyways, moving on ...
I am not at the board at the moment, but I do remember it has some exposed copper pads that I assume are test points. Any of those for the 3.3V ?
What would be the easiest way to test for a blown 3.3V regulator ? -
RE: Dead PanelDue 7I
Thank you for the response.
A lesson has been learned for sure.
I have read a great deal of the documentation dealing with the Duet and Wifi Board even before I purchased one, I was aware of many things not to do like plug and unplug motors under power, even remember reading the How to destroy your duet 2 article. I never saw anything warning against moving motors plugged in.
It does seem like that is something many take as a common sense thing, and it will be for me also in the future.
My only other piece of hardware is a CR10S pro, that seems to be completely immune to backfeed damage, so perhaps stupidly I was not cautious enough.Filastruder has already denied warranty, I am not quite so sure how I feel about it. I can agree that my actions may have caused the damage, just not so sure they should have.
Barring any warranty replacement, is there a repair service offered ?
If not, any tips for what to look for to replace, single component wise off the board. I am assuming (hoping really) a backfeed voltage spike would damage a single surface mount component such as a diode or capacitor, i have a reflow station and other tools required for that type of repair.I realize that it may be hard to diagnose what it is that failed, but lets say if I commit to spending up to half the cost of a new PanelDue dollars and a few hours of work, what would be the first things one should look at replacing ?

RE: Dead PanelDue 7I
Is there a more "official" place for me to ask these questions ?
Would the next step be to contact Filastruder where I purchased it from ?
Or sit and wait until someone reads this post ? -
RE: Dead PanelDue 7I
I am also fairly certain it is dead, but want to be sure I am not missing out on anything.
Next question of course would be is this covered under warranty ?
I have already ordered a replacement, even if I can recover this one somehow I can use it on another project.
I am a great fan of this product line, but on other printers I can move the head back and forth, and not kill parts of the printer. -
Dead PanelDue 7I
I have a dead PanelDue 7I. I may have accidentally killed it, though I don't think it should have died from what I did.
Looking for any confirmation that I did possibly kill it and stop spending more time on it if so.Has been working for a about 2 months without issues, using the 4 pin wire.
It was ordered from Filastruder about 2 months ago.
When I initially set it up I followed the online guide and flashed firmware up to the latest, so I am familiar with the flashing procedure and Bossa.What I did last night to possibly kill it.
In trying to identify a slight noise coming from the belt mechanics of a core XY printer, I had the printer turned off at the 120V source and moved the head around by hand, X&Y motors. At a pretty good rate of speed, guessing about 100 mm/s.
This lit up the leds on the board, and I decided to stop. Possibly too late.Turning things back on, the panel does a brief flash but will not do much beyond that.
Verified that the Duet Wifi board is outputting 4.98 volts to the panel.
Verified that everything else seems to be working, can connect to the printer via web interface and home motors at least.
Did not try anything beyond that such as heating up hot end or 120V bed.
Verified that both fuses are good.Several different computers and several different usb cables, with and without power from Duet wifi board will not detect the PanelDue plugged up to the usb port. This is including the computer that originally flashed the firmware to it, so it definitely should.
Have tried the erase button for a few seconds, followed by reset button, I am having no luck.
Screen stays black , backlight does come on, black screen will do a periodic flash if leaving it powered via the Duet Wifi 4 pin cable.
Any suggestions ?
Thank you
