Community repairs?
-
Hey all, just saw this post and thought I'd throw my hat in the ring.
Location: New York City, US
Contact: Through forumI've done logic board repair professionally in the past, like others I'm kitted out with the stereoscope, hot air, all manner of soldering gear etc etc. Also have a suite of test gear for more advanced troubleshooting (scope, 4.5 digit meter, function gen). 2.5 years experience microsoldering, and I've been doing through hole for much longer. Willing to take a look at anything for the cost of shipping both ways.

@pungoboy I'll edit the first post and link down to this!
Oh, and you is awesome!

Anyone in the UK then I can replace drivers and fets, I already replace 80pin Atmels in telescope mounts so these would be no problem for me

@MikeDC awesome; I'll update the first post and add you to the overview. Thanks!

I'm also sitting on some fancy rework gear and wondering if it would be beneficial for the community and environment to try and have these boards fixed by the community, including myself.
Yes, definitely! The most common repairs are replacing blown drivers (although those usually happen within the first few days so they are covered by the warranty), and blown fan mosfets. After that comes failed WiFi modules (and users wanting to replace the original module by the external antenna version), and occasionally failed processors - although when the processor has failed, unless it's on a v1.0 Duet WiFi then it's normally due to overvoltage on the +3.3V rail, so other components have probably failed too.
BTW we've shipped tens of thousands of Duets, so they are more reliable than you might think from seeing forum posts about failed ones.
I just recently started having an issue with my Duet 2 Wifi. I went to do a print the other day and started to smell something. I checked the power wires going to the Duet from power supply and the ones from power supply to the Duex5, I only smell it when the Bed is heating up. I can even hear something a little bit when it first starts to heat the bed. I know this topic was a little old but I was wondering if something needs to be replaced.

Might be best to start a new thread. This one is more dedicated to finding someone to repair something specifically. Please start a new thread with some more specifics of your setup and we can try and help troubleshoot what is going on. I'd also suggest perhaps disconnecting everything from the board and giving it all a good visual inspection before trying to use it again. Burning smells are never good and you want to try and limit the damage. See if you can find what burnt.

I am wondering how this "community repairs" idea is woking out.
Are there any stats how many community repairs been done so far?I recently replaced one of the stepper drivers in duet2.
Here are some pics from the process:- Some protection for plastic connectors and electrolytic caps:
- PCB after removing chip and cleaning up old solder:
- New chip soldered just before putting heatsink on, and sending board back:

Great! thanks for sharing.

Sharing was just extra. I was wondering how this works for others. And are there any stats / info how many boards were repaired by "community repairs team"
