  • I like to rag on Amazon as much as the next guy here, but this article seems a tad misleading. They do still show up when you plug them in. The article even says they use MTP now instead of functioning as a direct USB mass storage drive, which means you can still plug them into your PC and transfer files though File Explorer. Android handles USB file transfers the same way, and that works fine.

    Hey I just saw your update! I’m glad you’re getting better results, but like you mentioned, something is definitely still wrong. I’m still pretty convinced your nozzle is clogged, even though it’s new, and I’ll do my best to explain why!

    To start, if your printer wasn’t working normally before you printed in wood, I’m totally wrong about everything below and you can stop reading here!

    If your printer was working normally before you tried printing in wood though, that means the e-steps were already calibrated correctly, and they wouldn’t need to be re-calibrated after replacing the hot end. If you had replaced the extruder and it started acting this way, that would be a good reason to re-calibrate the e-steps, but replacing the hot-end shouldn’t have had an impact. After swapping an extruder, you calibrate e-steps to basically teach the printer how to extrude the correct amount of filament in the real world again since the new extruder might have different specs from the original and the printer has no way to know something has changed. A hot-end swap doesn’t necessitate recalibrating e-steps though because the extruder is the same and it’s still going to be pushing the same amount of filament through the printer.

    If your nozzle is clogged and you recalibrate the e-steps, the measurements you take will be off since the printer can’t push filament through at the rate it should be able to. Your new benchy looks better than before, but that could be because the higher e-steps you calculated mean the printer is now forcing more filament past the blockage by working the extruder more. It’s been calibrated to compensate for the fact it can’t push filament through fast enough, but it’s working harder to do this and it will severely limit its speed before it starts underextruding again. I’m guessing this is the reason for the 3 hour long benchy at 20mm/s? You shouldn’t need to be at 220 C to get PLA to print at 20mm/s from a 0.4mm nozzle either.

    Not all nozzles or hotends are well-made or handled with care at the factory. It’s totally possible you got one that shipped with some sort of tiny unnoticeable debris inside that worked its way down into the nozzle as the filament pushed it along. I have a cheap bag of 0.4mm nozzles that have metal shavings stuck in some of them and your first benchy is exactly what my prints look like when I use one of them. If possible, I still recommend changing the nozzle before doing anything more expensive like replacing the extruder. You’ll probably need to set the e-steps back to what they were before changing them though, otherwise you’ll be extruding too much filament if the new nozzle isn’t clogged and the old one is.

    The fact it won’t print below 220° makes me think it’s a problem with your hotend, and my best guess is that your nozzle is clogged. The higher temperature might be helping the extruder to squeeze a bit of filament around the clog, but not enough.

    Changing the nozzle is quick and easy, and most printers come with a spare or two, so I would give that a shot before diving too deep into diagnostics.






  • I got the Surface Pro X a few years ago purely for battery life, performance be damned. Great decision, and it fit my use-case perfectly. Maybe a little too perfectly for Qualcomm, because I have no reason to upgrade to something more performant when all I cared about was the battery life.

    Edit: This recent push towards Windows on ARM is also benefiting these old WOA devices. Programs that would barely run before (because they were compiled for x86 and had to be emulated on a chip that could hardly handle all that extra overhead) are now getting native ARM version releases that run way better. In my experience, my Pro X’s performance has effectively been improving as time goes on, so I have even less of a reason to get anything new.







  • The helium leaks weren’t and still aren’t an issue for the mission. They are an issue that should be addressed in the future, but they pose no safety risk as things currently stand. While Starliner is docked, it won’t even be leaking any helium. The tanks are sealed shut when they aren’t in use, and since the leaks aren’t on the tanks themselves, they aren’t losing any helium as long as they stay docked.

    The thruster failures are also not necessarily related to the leaks. They don’t know why the the thrusters shut down, but they were shut down in software and not due to some piece of hardware failing. Their current goal is to figure out why the software shut them down, and why 4 of the 5 that shut down were able to be restarted without issue. They aren’t just assuming it can maneuver either, they know it can because the thrusters aren’t broken. It didn’t require any physical repair work to get them firing again, it took a restart.

    Remember, this is just a test flight, and nothing that’s happening is outside the scope of the test.


  • They’re not stranded because Starliner is capable of reentry and is already cleared to be used in emergency situations. In fact, the two astronauts had to prepare for an emergency undocking earlier this week when a Russian satellite broke up and the station’s crew was ordered to take shelter in their respective spacecraft.

    The helium leaks are also still not an issue either. The new leaks aren’t “new”, they’re just so much smaller than the first one that they took much longer to be detected.

    It’s still docked to the ISS, not because it can’t leave, but because they don’t want it to leave until they collect all the data they need. Part of this data collection process is supposed to involve 2 spacewalks to examine the service module, but those spacewalks haven’t been able to happen yet. Technical issues with the EVA suits prevented the first one they had scheduled from happening. The ship is still fully capable of maneuvering too, they are only down one RCS thruster out of 28.
