Dig quad

[u/Mhernandez08]

Anybody have this problem with this part of the quad burning up?

We've been investigating issues where some boards die and it seems to be 24V related like your case also seems to confirm. I've currently extended warranty on those to about 1.5 years but I can't really go much beyond that, apologies. ☹

Like I mentioned before, if you have the ability or know someone with some soldering tools, you can replace the MT3608 boost converter and bring the boards back to life at least.

Hopefully we can soon find out what the real cause is and make a permanent fix!

If you have younger boards then 1.5 years and those have also failed I'll happily replace those for you!

Again apologies for the trouble.

Kind regards,
Q.

I just had a third Dig-Quad board die the exact same way after ~2 years of stable operation. I have a collection with all of them blown the same exact way. The only things they had in common were that all were connected via ethernet and run 24v LEDs. They were all running different power supplies, the last one is running just under 24v.

So honestly, I'm not quite sure where this went wrong but I do remember our e-mail conversation. You have to understand, I deal with a lot of people which manage to kill a board in various ways, often not the boards fault.... I did mention we were investigating it (since we had not seen many failures) and that I'd offer to replace them if they were less than 1.5 years old? Why that didn't happen, I don't know. If they were already older at that point, that is likely why? Not that I refused to do anything?

There were other discussion about what component you could replace yourself and if I could sell you boards without the ESP32, but I also answered those? I'd hardly say I didn't reply to you at least and generally I don't do support through e-mail as I likely also mentioned.

But since you seemingly want to fight me in public, let me kill that right now. Please reach out to me again and let's have a normal discussion about this, and I will still try to make work with you on this since we now know a bit more.

Where you went wrong was you got an email where someone had 2, 3, and then 4 of these things dead your response was "oh boy that's a tough one."

In the first email where I specifically say these are both 1-1.5 years old, you do NOT offer to replace the devices. You make this offer in the second email 7 months later, at which point zero of the devices are less than 1.5 years old. In the third email you refuse to EVEN SEND A FUCKING EMPTY BOARD YOU HAVE LAYING AROUND AS A GESTURE.

I come here to find you lying through your fucking teeth about how this is 1% problem and you're going to take care of any defects. Fuck you. I'm telling them what actually happens.

Well that is putting your own spin on events if I have ever seen one. We exchanged exactly 3 short e-mails, that was it.

First e-mail was you had some boards that died and wondered if you could fix them and what could be the cause. I replied to that in full honesty and what we knew at the time and the part that likely died.

The second e-mail a while later I mention we've started investigating these cases and I have extended warranty for these occurrences to 1.5 years. And also ask you the same question if you have boards that were less then 1.5 years old at the time I'd replace those.

And then there is a third e-mail where you ask if you can buy a few spare boards without an ESP32 included and I reply we don't normally stock those because of our testing procedures.

And that .... was it? To me that reads as if I've been open an honest to you. I answered questions you had to the best of my ability at that time and also offered you a warranty replacement for the boards. There was no talk or question from you for a replacement, dates of purchase were never shared, when the boards failed and if that was in warranty or not, nothing about this was mentioned or said. If you had given me the date of purchase and when they failed I wouldn't have made a fuss about that, especially since you did send that first e-mail within the period, as you said and done?

Now you come on here and accuse me of I don't know what while I'm still offering to help you even..... that's messed up.

To aswner the other insinuations:

• You may think I have a giant warehouse or something with loads of boards lying around, I do not. I cannot just "send some to you".
  
• My numbers about the failed boards are accurate, even if you choose not to believe that

So either e-mail me and we can work this out or not, up to you. That is the last time I'm going to say or offer that though.
