@karrad That is standard quality with supports enabled. I did reduce the support density a little bit, just to try and save on material.

I'm not sure if lengthening the wire would really help that much. It seems like the wire would still have the risk of coming out of the crimp, like we have been seeing. When the ring terminal is tightened onto the screw under the motor it makes the neck of the connector bend, which might be a part of the problem.

bigmansas added a comment to T6798: New middle foam insert for packaging.

The second drop test with the new foam went well. It looks like the retaining rings all stayed where they should have and the toolhead zip-tie did not break this time. The only problem I saw was the 5v fan wire pulled about halfway off the pins that hold it in place at the RAMBo board. I couldn't get a good angle to get a picture of it, but tried none the less. I also accidentally pulled the y-axis ground out of the connector when taking the bed off the machine to box it up for the drop test.

I just did round 2 of drop testing a Redgum and this connector became unseated again, however it did not completely come lose this time. I was able to push it back into place on the second drop test.

I noticed some warping going on at the lower layers of a print. I ran 2 tool caddies which took over a day to print, and I'm not sure if the longer than usual print time could have cause the warping.

One thing that I noticed on a Taz Pro that I was giving a once over after the calibrators got done with it, was that the ground screw that connected the USB thumbdrive to the RAMBo was not tightened all the way. I'm not sure if this could cause the thumbdrives to short out, but it's a thought.

One other thing I noticed that is not in the drop test documentation is that when unscrewing the bed screws with the NinjaFlex bands on them, is that the bands tended to hold onto the screw and screw around it when loosening the bed bolts, which could cause the band to possibly break.

bigmansas added a comment to T7620: Cube prints cosmetically worse than mini.

I have been working on this over the weekend as well as today, and it looks like a heating issue, possibly from the parts cooling fan sucking in hot air off the bed, which prevents PLA from cooling fast enough and leads to warping. I ran 5 test cubes so far, 3 of them at the back of the bed individually and 2 in the center of the bed with a desk fan setup behind the printer to help cool the cubes. I also ran a 6th cube with the same .gcode but no external fan blowing on the part. With all of these cubes, I used a bed temperature of 60C for all layers, to try and help reduce the warping, it seems like the higher bed temperature was causing it to be more noticeable.

bigmansas added a comment to T7651: Material Combo feed back -PLA/PLA.

I've been having issues with heat creep happening pretty quickly into any larger/longer prints, so I reduced the temperatures down to 210C on both hotends with some Polylite PLA. I've had a test print going for roughly 8.5 hours now and the heatsink are slightly warm to the touch, but no signs of heat creep yet. It looks like the with lower temperatures, a person might be able to increase the skin overlap percentage to try and get rid of the seam lines that are very noticeable when going between colors. I've got a few ideas for a couple more changes that might help, however I haven't had the time to test them yet. I would be happy to include any notes here, once I've had a chance to make a couple changes. I just don't want to make to many changes at once, for testing purposes.

bigmansas added a comment to T6806: Frame QA - Z-Motor fasteners.

If possible we should also add to "Check z motor screws to make sure they are not cross threaded and sitting flat against the 3d printed part." I don't know if this is still a problem, but it had been a problem last week and prior. Due to the angle of the hex driver needed to get the z motor screws screwed in, they have a tendency to cross thread and go in at an angle, if not careful.

I checked a few of the Taz 6's over here and a couple of them seem to be a bit off. We've got one that says it's been used for 20 hours, which seems a bit low for our printers over here, and then another one that says around 2 days of print time on it, which also seems a bit low. We have another one that shows 13 days of usage, which seems a bit more in range.

I just put 30 files on the USB drive and they were 4.2MB per file. It seems like there is a slight delay (a second or less) when cycling between the 4 screens worth of files on the LCD screen. 50 of the same files gives a delay of about 3 seconds. 70 gives a delay of about 5-6 seconds and for some odd reason the screen flashed and the z axis homed itself when pressing the USB drive button.

bigmansas added a comment to T4931: Alpha User Testing Feedback.

Most of my answers are still the same as the previous notes I left, however with the latest firmware on the machine (2.0.0.78) it looks like the level x-axis has been removed and I also was still getting a lot of false triggers from the endstop sensors, so I messed around with the Runout Detection Distance. When I set it to 30, it would still false trigger a lot, so I bumped it up to 50 and still had problems. Once I bumped it up to 200, I was finally able to complete a print with only one endstop trigger for no reason, rather than getting one every 2 minutes or so.

All three profiles seem to work pretty well, however the prime tower gets positioned on the back side of the bed in the grey area. I have tried uploading the profile with a change in location for it, however Cura seems to not save it, or allow me to export it out, or even find it under the Manage Profiles. The positioning I was using for testing was X 30mm and Y 10mm which positioned the prime tower on the front left of the bed.
