nothing that says what it does.
(would that be too much to ask for… Elegoo? or whoever made that board. those LED’s cost money. It’s such a shame they don’t have a top level “troubleshooting” guide that lists what they do… /sigh)
Comment on Elegoo Neptune 3 no longer turns on
papalonian@lemmy.world 8 months agoI was unable to flash the firmware. Putting the SD with the stock firmware does nothing to alter the behavior. It’s still just a blank screen with the backlight on.
Here’s a link to the PDF I found of the board’s schematics, if you’re curious. The LED that lights up for me is on the 3rd sheet. All the others are connected to the hotend, bed, fans etc.

That LED is normally on. It’s been about a year since I’ve had the chassis open so I can’t recall if there are normally more than one on when it first boots up or if it’s only the one. Looking at the diagram it seems like it’s just a main power indicator.
Thanks for taking them time to respond. You may not have been able to fix the problem, but you’ve at least assured me there’s no other troubleshooting steps I can take until I hear from Elegoo.
I guess my DnD players will have to live with quarters and pen caps in lieu of customized minis. Haha.

I found this diagram for V2.2 which looks the same. The lit LED is D5 which is the one you mentioned on the 3rd page. It looks like it only indicates that the 5V to 3.3V regulator beside it is working and has power.

That LED being lit at least more or less confirms that power is not the issue. Thanks for digging that up.

I read a lot into that “Haha”… like “They wont live that long anyway,”

It’s my very first campaign. I’m actually afraid the combat and encounters are going to be laughably easy, since I’m running a premade campaign made for beginners and I don’t feel comfortable yet tweaking with monster stats.

Hey, in case you were curious, Elegoo emailed me back and diagnosed it as a motherboard failure. And since I’m a couple months out of warranty, they won’t send me a new part. 😔 I’m now debating if I want to pay for a new motherboard and wait a month to get it, or just save up some cash and buy a better printer a month from now.
FuglyDuck@lemmy.world 8 months ago
A few months out of warranty? That ain’t suspicious timing….
It sucks that you’re down for a month. But, you don’t necessarily need to get their board.
papalonian@lemmy.world 8 months ago
Yeah, I figured there are other places to get it, but when it comes to circuit boards and whatnot (especially ones from China) I’m always a little hesitant about getting off brand stuff. I figured I’d see what quote they hit me with and take it from there

According to elegoo’s firmware instructions, the screen itself has updatable firmware too. Maybe you could try updating that as well
papalonian@lemmy.world 8 months ago
Thanks, I had forgotten about the screen firmware. Unfortunately, I just tried that, to no avail.
