oliver added a comment to T9605: update mini2 calibration model .

@tutley Mini 2 calibration will be printing these along side the current octopus calibration and evaluating the octopus for any issues to see how those issues translate to the new file. We will be bagging both the octopus and the new calibration print in the same bag and labeling it with the serial number, date, and the name of the calibrator. Any issues with the octopus will also be included on the tag. This will continue on for approximately 2 weeks where we should be able to attain over a hundred points of data.

@tutley I have a slice created that is around 55 min to print. I'm going to talk to calibration about be on the look out for each of the issues so we can get some testing done to see how well this print will be able to show these issues. Possibly working with cluster as well will be beneficial.

oliver updated subscribers of T9664: LCD Center holes do not line up with lcd board controller.

Working with @tutley and @logan, It looks like all 3 of the lcd parts are being printed almost a full mm under sized. These will need to be resliced to account for them being undersized.

oliver added a comment to T9664: LCD Center holes do not line up with lcd board controller.

@DaniAO I wasn't quite sure where to put the bowing cover as it does seem to be due to an issue with alignment somewhere.
@tutley The bowing could also be due to having to print the lcd covers but the mis-alignment for the lcd center seems to be on all of the parts.

@kent The machined metal that these screws have to go through is 11mm before they enter the threads on the motor. I don't think 1mm is enough to properly engage those threads.

oliver added a comment to T2220: Inconsistent skirt measurements.

I have a machine here that I can not get within spec on fw version 1.1.8.62 but was able to get it in spec with fw version 1.1.9.34. The other interesting thing was when I flashed back and fourth between the 2 firmware versions I noticed that I needed a different z offset or else my print would come out squished.

Wed, Jul 31, 3:38 PM · Mini-Hibiscus
oliver updated subscribers of T6683: White screws.

If we are using these screws on alphas than this will be a big difference on the Mini2 final frame and frame assembly and we will not be able to use those assemblies due to wrong part numbers. So the one that will be built with the stainless steel screws cannot be built using the same MO process and inventory (@tomc) will need to adjust those for affected assemblies.

oliver added a comment to T9210: Mini 2 Production firmware detects the wrong toolhead.

There is no other error shown and it will update except that I seem to need to change the z offset anyways because later firmware seem to be handling something differently.

Wed, Jul 31, 12:13 PM · Mini-Hibiscus
oliver added a comment to T9210: Mini 2 Production firmware detects the wrong toolhead.

@karrad I think this is still an issue for Cura. Since we are flashing with an older firmware that no longer shares the name with the toolhead, it is going to wipe away any calibration data that we have done and affect the customers first print. Even if we get the firmware updated in the CO, there is still going to be a lot of Mini 2s out there that will have an older firmware that registers as a improper toolhead.

oliver added a comment to T6644: Increase in the number of issues seen on LCD Screens.

@DaniAO @logan These are tested at 100% in Electromechanical before and after being put on the chassis. With the double checks we are still seeing instances of issues cropping up on these screens in calibration. Whether its a defect in the assembly or improper handling we do see instances crop up on the ultimachine LCDs and any printer that uses them (though I think the Taz 6 had the larger amount and so the redgum may be more susceptible.) As for how frequent, I cannot say as I havn't been in charge of red tags for awhile but they do seem to happen a lot less frequent than they did with the reprap lcds.

it seems like the z line may not be completely caused by having loose bearings and only further aggravates the defect.

Will do some further investigation into the seam along the z axis and create a new ticket if needed.

oliver closed T1289: Wipe sequence off center as Wontfix.

Talking with production, it sounds like this issue isn't as much of a concern to production as it has gotten better. Part of this could also be due to having an older firmware which is being addressed in a current change order. Closing this ticket as "wont fix" for now as there is several tickets with a higher severity that may require an update to this in the long run.
