  • If this was during an auto level, it’s my humble opinion that this is a manufacturer’s defect in the machine that caused the damage. There should be proper coding to ensure that any increase in sensor pressure by (delta p) halt that machine and that there should be a pressure offset in the sensor such that a loss of signal or anomalous zero reading or lack of reading is done prior to levelling to ensure that a sensor failure has not occurred. My XL freaks out if a fan isn’t spinning at the right speed, so they clearly know that a nominal operational check before the print starts is proper engineering design.

    Of course you won’t get anywhere. Unfortunately, a lot of 3D print failures really are user error so I suspect that’s their default response and it takes them a good deal of proof to push them of that mark.


  • Indeed, I’m not sure even testing is sufficient. My family recently got it (my wife and I visiting my parents), but thought nothing of it for a week. My father had a sore throat, my mother had watery eyes and some nasal congestion. My father masked indoors (because I don’t want a regular cold either) and chalked my mother’s symptoms to seasonal allergies (the cars were covered with Pine pollen all week). Then, on the drive home, my wife felt off. 10 hours in the car together. She slept in the guest room that night and, just for grins, tested for Covid the next morning. She was positive. We called and had my parent’s test - both positive. I tested negative so I packed my things and rented a hotel room for the week and worked there alone. I tested every other day and was never positive, but I cancelled all my client meetings.

    I still never “got it” but…is it really feasible I didn’t have some low level? This is my second trip in a car for multiple hours with someone who tested positive the next day. Granted, I’m about 4 vaccines in (2xOG, 1 updated, 1 XBB variant), but so is my wife. I have to think that I had some sub-clinical level of viral load, or at least below the antigen test threshold, but I’m thankful I escaped symptoms.









  • Very likely. Lots of super geeks on staff.

    But it’s also possible some astroenthusiast did the math and emailed it to NASA, and whoever got that endo thought it would be cool and passed it to someone who could schedule the instrument. If you think about your geekiest friend and how they’d react if you sent them something truly unique about their geekdom that they could act on - well, that’s pretty much how every engr/scientist at NASA would react.
