We should add christian as a subscriber to this ticket then.
@MikeR from Kent, when discussing design review of machined fixtures prior to fabricating them "For now, the plan is to leave the process as is, and revisit this issue with our new Manufacturing Engineer."

@tutley have we gotten the new jig milled out yet?
May 24 2019
With CO0038 complete (T6321) this is no longer an issue.
May 23 2019
This is now merged into master. Sorry for the delay, I missed this one.

I have passed this information back to igus. Resolved.
sorry it took me a while to get to my emails. i can confirm the mounting configurations @west posted above
EL-HR0141 -30mm chain config #2 20mm chain config #0
EL-HR0140 -20mm chain config #2
EL-HR0130 -30mm chain config #1 20mm chain config #3
El-HR0135 -20mm chain config #1
please confirm the mounting configuration for the assemblies that we are building EL-HR0140, EL-HR1041, EL-HR0130, and EL-HR0135. They should be Config #0, or Config #1.
Josh, please specify config # for each
if this is for EL-HR0141 then the 30mm cable chain needs config #2 and the 20mm cable chain needs config #0
@tutley can you confirm
@kim for which harness?
Closing this ticket, we can open a new one for future development and testing.
Closing this ticket. We can open a new one for future wiper development/testing.
@Galadriel I removed the extra boms with change order CO0044- just need to have it review and pushed.
Since there hasn't been an updated on this, going to close this one down. We can always reopen it if the problem pops up again.

@wolffchadd This is a valid request, however, I don't think it makes sense to go back and change products that have already been released to production (unless basic function is broken) and instead we should focus on designing new products which include the features that we would otherwise add to old products, such as these QC checksheets.

@tutley thank you!
pdf's in branch T7117
@DaniAO no change order needed for this i presume?
its just adding another file type. not changing anything
@DaniAO Yes, among other things, but this issue was the primary focus. The current slice doesn't have this issue.
Any updates on this? if not this ticket can be closed.
@samantha this was fixed in the change order 36 right?
@logan was this fixed with the most recent case update by chance?

Thanks for the info! The reason I asked for it to be changed was because we had a customer who found this BOM and emailed us to double check on what was listed because he almost bought the wrong type of motors to have as a spare part. I was hoping to avoid the risk of this happening in the future since not everyone will take the time to double check and I would hate for someone to buy the wrong part based on something that is in our documentation. Could we mark this as specifically for engineering or remove it from the download.lulzbot repository and just keep it on devel to reduce the chance of people finding it?
@Galadriel this isn't the BoM that is used in OCA. This is the engineering Bom that was used to create the original manufacturing BoM that was then used to create the BoM in OCA.

We had another RMA for an LCD screen issue come through, serial number: KT-PR0041EU-28127
It seems like most of these are from RRD. I will continue to update as I see them.

@david.hall Projects/mini-hibiscus/production_parts/tooling/fixtures/ should have what you need!
@tutley we can set that up. I will need to know where the file is for the fixture.
@david.hall until the fixture gets updated with the milled one, can we try and reprint the printed fixture to see if that makes an improvement?
Apr 23 2019
@tutley Thanks, I believe that this is the ticket to figure out what is wrong with the alignment. The broaching is simply to make the parts work on the line right now so that we don't throw away all the printed parts. MER should be trying to resolve why we have the issue. Perhaps they could get some help on it.
The reamers are changed regularly and we are reaming slowly. The last information from MER was to do a 3 reaming pass (slowly) to see if it assists at all with the issue. We will be glad to print with a solid fixture when that is ready and we can see if that will help with the issue at all. Just making things work while the issue is figured out.
@david.hall These changes should have gone through an MCO.
With proper reaming we shouldnt need to broach all the parts. Also i suspect the rise in binding may actually be coming from broaching all of the parts, as it is very easy to make the bore not aligned with the axis of motion when broaching by hand. (hence the issue with the orientation of the parts once installed, both bores are not parallel)
@oliver that is because of the amount of drag that has been on all of the parts. To get them to be okay on the printer they have needed less drag than the spec, so we have been broaching all parts. They are all checked for drag before they leave Cluster, and only once inserts are put in does it appear that the drag increases. This has been an issue with the parts since we started printing them, but the issue seemed to get worse some time ago (perhaps 1 1/2 months). We should note that the drag is not due to the bushing that is installed. it is due to the orientation of the 2 parts once they have been assembled and tightened down on the printer.
@tutley As far as MER is concerned we have not heard of any changes, though I was told that they are no longer using the force gauge to check the drag on the parts in cluster.
@oliver have there been any changes to the mfg process?

With the thermal gap filler kits this isn't an issue and the assembly instructions can be easily followed in reverse for removal and replacement.

@adam it was at s/n KT-PR0041NA-31341 when we started.
@bowman do you have the serial number of the printer where we switched from RRD to ultimachine?
We sure do!
We did recently switch to a new supplier for the LCDs, so we should probably start with determining if these were from the new or old supplier. Do we have serial numbers for these machines in order to determine that?
Apr 11 2019
we may need to look at the x ends as well
