  • So to start with, you mentioned the underextrusion on a previous print. Seems like a good starting point, when was the last time you checked your E-steps? Basically you want to disconnect the bowden tube from the hotend, extrude out a short amount of filament and mark its position, then extrude 100mm of filament and measure how much actually came out. From there, there is a formula to adjust the E-steps on the printer. Ideally you should have exactly 100mm come out but there’s a good chance you’re going to have less than this. You can also make some adjustment to this from your slicer (in the material flow section) but that can cause various other problems, so ultimately you’ll want to get this value corrected in the printer itself.

    While the bowden tube is disconnected, this is a good time to try doing a cold-pull. Heat the hotend up to around 200C again, stick some scrap filament into it so it just starts to push filament out the bottom, then let the hotend cool back down to near 160C (or maybe even cooler, but this is a good start). Pull the blob of filament out of the hotend, and you should have a bullet-shaped plug on the end of it. Look this over to see if there is any burnt filament, contaminants, or anything else that looks weird. If you see obvious contaminants then this is likely causing your underextrusion. After doing this, you should also check the nozzle itself, sometimes as they wear out a bit of the brass gets pushed over and blocks the flow. Always keep spare nozzles on hand, they wear out faster than anything else.

    And one more thing before reassembling… Check the extruder itself. After some time it is common for the brass gear to get clogged up with filament or simply have the teeth wear down, especially from some of the fancy filaments like wood, glow-in-the-dark, or even the metallics. However the results of these problems should be fairly obvious from a clicking in the extruder while printing. Clean out any obvious filament remains, or you can get a pack of replacement gears pretty cheap.

    When you are ready to reassemble the bowden tubing, check the fittings at both ends. These wear out easily, so you may see signs that the tubing have been shifting back and forth. These really need to prevent any movement in the bowden tubing, so if you’re going to order parts anyway, get a pack of these to hand on hand. Bad fittings can cause serious underextrusion any place the extruder reverses directions like at the end of a wall. but the wall itself should lay down fairly cleanly.

    Hope that gives you some ideas to run with. Some of this will depend on the specific model of Ender you have, but if it was working fine and just suddenly started having problems then something blocking the filament flow is at the top of the list of possibilities.



  • I read this as a sign that his lack of action during COVID was in fact intentional. He also confirmed his intent for the 25% tariffs on Mexico (which will raise food prices) and on Canada (continuing the problem with new housing being unaffordable). Plus he signed another bill today demanding that US history taught in schools be white-washed of those “troublesome” notions like slavery. Taken all together, it’s obvious that the oligarchy wants the working class to be broke, hungry, homeless, and stupid enough to vote for his type again.

    Your king has spoken. Long live the king.

    [Edit] More news on the health care front… He’s blaming WHO for his own gross mismanagement of the COVID-19 pandemic, and he has pretty much gutted every program that aims to keep health care and medication prices manageable. Isn’t it funny how someone who ran for office on the idea of making things more affordable for everyone has already in his first day made costs skyrocket? https://www.statnews.com/2025/01/20/trump-executive-orders-health-care-drug-pricing-aca-covid-gender-discrimination/

    Only ten years old? Hell my desktop is around that age, doing just fine. I do need to get some more memory though, 16GB isn’t quite cutting it for the number of programs I’m running simultaneously these days (and having 2500 open tabs in firefox doesn’t help). That’s the beauty of linux though, it never forces you to upgrade or chokes out your system with unwanted ads and background processes.

    Honestly if you were expecting a drive failure in three years, you probably have some other problem. The SSD in my desktop is clocking 7.3 years and I never shut down my machines except to reboot. On my servers, I have run used HDDs from ebay for up to ten years (only retired for upgrades). My NAS is currently running a mixture of used drives from Ebay and some refurbs from Amazon, and I don’t anticipate seeing any issues for at least a few more years.





  • More drives also equals larger power consumption so you would need a larger battery backup.

    It also means more components prone to failure which increases your chance of losing data. More drives means more moving parts and electrical connections including data and power cables, backplanes, and generated heat that you need to cool down.

    I’d be more concerned over how many failures you’re seeing that makes you think smaller drives would be the better option? I have historically used old drives from ebay or manufacturer refurbs, and even the worst of those have been reliable enough to only have to replace drives once every year or two. With RAID6 or raidz2 you should be plenty secure during a rebuild to prevent data loss. I wouldn’t consider using a lot of little drives unless it’s the only option I had or if someone gave them away for free.

    I started on a 50Mbps plan which was a massive upgrade from what Comcast offered at the time, so I was pretty pleased with that. At one point I noticed something dragging down my connection, and found signs of people attacking my servers. That was easily dealt with, however what surprised me was the speed of the traffic I was seeing. After blocking the attack I pushed up my torrents and realized I had been upgraded to a 100Mbps connection and didn’t realize it (I really do love my local provider!).

    So yeah, for general web browsing you probably won’t notice any difference between those two speeds. If you are downloading specific content then of course the downgrade will take twice as long, and as others mentioned it shouldn’t affect your streaming speeds at all.



  • I dunno, I feel like there’s a distinction between being timid and being cautious. Yeah we all wish things could have ramped up much faster and knocked Putin back to his bunker like a coward, but if we had misjudged his readiness then there might not be a Ukraine left today. We know better now, and I think Russia’s disastrous ICBM testing gave everyone a good idea of what to expect. And the fact that they’re not turning to North Korea of all places for support? Yeah it’s not looking good for Russia’s military.


  • Yes, and they were given artillery shells. They were also initially given short-range missiles to limit the range of attacks so Russia couldn’t claim we were arming Ukraine for an all-out attack on Russia. And then as more information came in about the state of Russia’s military, better missiles were supplied.

    The whole point of this was to prevent provoking Russia into a full nuclear launch. It’s only been two years, did you seriously forget the concerns with the US getting involved at all? Russia claimed to have the largest arsenal of nuclear weapons in the world, and there wasn’t much solid information to contradict that claim. It sounds to me like you think everyone should have risked a global nuclear meltdown against a small man who acted like he was the toughest kid on the block, rather than playing it safe in case he really did have all those nukes ready to launch. Sure, NOW we know better, but in February of 2022 there was still a reason to believe he had the capacity, and we certainly know Putin is mad enough to have pulled the trigger.
