The report is complete though I don't like the formatting of the template (I think I was supposed to delete all the pages I didn't use). They forgot to screen the supplier name and there are some things we can't easily check such as the exact shade of white powder coat. Dimensionally these check out and I think aesthetically they are passable so I think we are finished here @oliver.

kent updated subscribers of T7423: Threads pulling out of extrusion .

I checked some of the extrusions that we built the alpha units with and they had a minor diameter of 4.45 on average whereas the red tagged extrusions that we are seeing this issue with have a minor diameter of 4.75 on average so that explains it. I'll coordinate an inspection of the backstock and generate the NCMR. I will need to determine a threshold maximum minor diameter for these threads. @tutley @samantha do you have any recommendations? From the documents I've found, M5 x 0.8 threads should have a maximum of 4.33mm minor diameter, but I was thinking we could approve a variance up to 4.6mm without running into any issues.

@DaniAO, as part of this bugfix we need a new PN because we split out the final QA from the calibration QA. Can you create a new DC-MS PN for Calibration QA record? We can probably re-use the PN for the final QA record, unless that will be too confusing. If so, we will need a new PN for that too. Currently the file names for the QA checksheet have placeholders in the T6814-T6848-T6806-T6924-T6853-T6852-QA-checksheets branch.

@EricNugent I like the skirts. I think it would help to put a pause command in there so you could inspect the skirt and make adjustments then resume. The new edge in the model doesn't prevent the blob and does this high-ish frequency infill on the first layer that is kind of slow. The tower is too fast and melty. It took 26m 16s to print for me.

I noticed while I was printing yesterday that the ooze is happening during the pre-heat of T1, which happens while T0 is printing the last part of the layer it is on. The pre-heat starts ~50 seconds before the nozzle switch, but the extruder reaches temp in about 25 seconds so it just sits there at temp for about 25 seconds. I looked through the cura settings a little but didn't see any setting to change the pre-heat time, but I think it would help the ooze and blob artifact we are seeing if we could reduce this pre-heat time.
