Galadriel added a comment to T8411: Uptick in the number of RAMBo failures.

I am currently going back through the instances of failures listed above in a bit more detail and thus far I have found at least 1 additional issue that I listed that upon closer inspection looks to not actually a RAMBo issue. I wasn't able to get through everything today so I will have to finish and update this on Friday when I am back in. I just wanted to update to make sure that people knew it is still on my radar and I should have things better situated on this ticket on Friday. Sorry for the delay!

I have already set up an RMA to send him the new one-piece as well.

logan added a comment to T8411: Uptick in the number of RAMBo failures.

Since he's seeing the exact same issue as before the RAMBo was swapped, has everything else been checked? Specifically the internal and external bed power harness that @kent suggested checking in the ticket, which is a common failure point. If that hasn't been checked you should consider sending the new one-piece version along with the RAMBo.

@Galadriel Ouch! Missing 90% of the LCD header. Have you suggested upgrading to 1.4? I'd send them the harnesses free of charge at this point given their trouble, personally.

@kent @mjpelletier @Steven New one to add to this list, ticket ID 207,731. Customer bought a new 1.3L RAMBo from us and it came with pins missing, based on photos looks like the pins were never installed. Reference for purchase of board: SO103180.
We will be sending customer replacement board, would you like us to get this one back so we can check so serial number on the board or anything?

@TyTh we still haven't received any known failed boards in R&D to look at. @mjpelletier is back in the office on Tuesday so if we have a few of them to look at by then we can look them over.

@Galadriel can you make a list of RMA's that resulted from these RAMBo issues and post it here? @MikeR @bigmansas @oliver @zachah @logan @EricNugent @franklin if you repair one of these RMA's hang on to the boards so we can give it to @mjpelletier and he can do some failure analysis.

Some of these helpdesk issues resulted in RMAs, so they are going to be down in MER on the green pallet in machines awaiting repair, or if they have already been repaired, they will probably be in the electronics scrap bin.

sherylb updated subscribers of T8411: Uptick in the number of RAMBo failures.

In speaking with Kent, this is not so much a vendor quality issue as the errors relate to other issues. These units were tested prior to leaving Aleph and passed. Some of the RAMBo's were installed by Customers which could lead to problems. Some of the tickets are not RAMBo issues but other issues with the printers. If it is truly an electrical issue can @mjpelletier look at the tickets and see what his conclusion is?

AOJAS added a comment to T7483: Taz 6 Control box PEM nuts crooked.

Oliver and I have talked to PMM about this. They have suggested that the holes should be centered on the flange rather than offset towards the curved side, because their machines have trouble putting the inserts in so close to a curved edge. I told them to submit a redesign to Josh Perry to be approved by R&D to improve the manufacturability of this part.

bowman added a comment to T7483: Taz 6 Control box PEM nuts crooked.

Steven and I found that most of these will be acceptable by tightening the screws a little more and they should be okay. If there are any that look extremely crooked, then we will have to correct it by either re-tapping or replacing the chassis.
@guadalupe Please keep a look out for these when using any chassis to build boxes. Make sure that the pem nuts are straight.

I didn't find the MPN on the datasheet you posted, but I searched it and found https://we-supply.com/heat-shrink-tubing-1-2-x-4-31-adhesive-dual-wall-black-dwhst12bk4 which looks like it will work fine.
