BLTouch/Fried board
-
OK, thanks, I purchased both items from E3D, I'll contact them a little later.
Should I include the Paneldue as well, is there a problem there seperate from the above?
-
The problem with the PanelDue is almost certainly a bad crimp at one end of the cable. So you could ask them to replace the cable - although they may prefer to replace the whole package.

Hi David,
I have spoken to Daniel at E3D with regards the WiFi board, I understand I have to return it to him along with a reseller warranty form, if this is correct I can arrange that.
Regarding the Paneldue 5i, I would like to have that fully checked over, although I said it worked with the short ribbon cable, which it did, now I think about it a fault was reported in a small red box in the top right of the screen prior to me disconnecting it.
Do I need to fill out another warranty form or just return both items under the one claim?

Please fill out 2 warranty forms, so that we can feed them into our failure analysis system.

Will do, thanks.

I realize that this is an old post, but I just had this exact same thing happen to me. I'd like to understand why it happened to avoid it again.
I have a Duet 2 Wifi 1.04b which I've been using on my TronXY X5S 500 and I've just purchased a genuine Antclabs BL Touch Smart V3.1.
I followed the installation instructions here: https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_connecting
and triple checked my wiring, but when I powered on the board, I got flames coming from the corner of the U3 chip. This is outside the warranty period for the Duet board, but if I'm going to replace the board, I don't want a repeat experience. They're too expensive to ruin.Thanks for any thoughts.

@StevenHerbs please start your own thread

I intentionally replied to this thread instead of starting my own because of the similarities.
I'd been hoping @dc42 would be able to weigh in on this.

@StevenHerbs By any chance does your BLtouch have the word creality anywhere ? If so the wiring is different. That has caused many a board to release the magic smoke.
-
@StevenHerbs please post a picture of your wiring, at the Duet and at the BLTouch.
U3 is the 5V regulator, and while a short to ground can make it fail, feeding it 24V is the only way to make it go up in flames. Did it go up straight away after turning on? I’d check proximity to hot end heater wires in cable runs, look for a short between that and the 5V or servo wire.
It may be repairable. You can replace U3, see https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#voltage-regulators-1

No, zero chance. I have both and it's impossible to confuse the two. This is 100% genuine BLTouch V3.1 from Antclabs.

Thanks for the info. No, it took part of a minute before it started shooting open flame. I didn't install the BLTouch on the carriage yet - I had it loose by the board, so the cabling wasn't anywhere close other wires to short.
-
Apologies - originally missed the request for the BLTouch end of the wiring.
-
@StevenHerbs Looks to me as if your 5-pin plugged into the BLTouch is backward. From left to right it should be:
Are you using the geniune cable? Perhaps you used the Creality one on accident?
Above info taken from the Zprobe docs, image below for reference.

You've got to be kidding me......that's such a simple explanation. It hadn't occurred to me that the wiring order at the BLTouch might have different standards. I hadn't found those charts you shared before, but that explains everything. While the BLTouch IS authentic from Antclabs, it is boxed in a Creality box and wired for Creality applications.
At least I understand the reason and how to avoid a repeat. Thank you!
-
@StevenHerbs That was why I ask if it was associated with Creality in any way. That little change by Creality has caused many cases of magic smoke release. Both by Creality board owners who bought a non Creality BLtouch and vice versa.
-
@StevenHerbs Sorry to be the bearer of bad news! Hopefully you try that U3 replacement, as that might work out for you!
Agree with @KenW, for reasons unknown Creality and Co have screwed with plenty of DIYers with their change.
-
@sebkritikel and to add insult to injury, wire order and colors are depending on the lot you get.
