  • 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.








  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.










  • I’ve had it for 15 years and just replaced the seat cushion last month.

    I have 5 cmdrs in elite, I think. Only one is on Odyssey. One Horizons-end-game-all-but-carrier with 6B credits and a fleet, one stuck 15,000LY in the black, two with T-9s I made for commodity storage, and one new play through that’s mid-game (the odyssey one). I’ve mostly given up since I don’t have the free time / desire to grind for alien fights and the new on-foot and eco-bio stuff just doesn’t wow me.
