  • Help! What is wrong?

    Jump

  • All right, I think you are right on the curling upwards. I started another print, which is also using similar hexagonal sides, but is more massive - hexagons are larger, and walls are thicker. And it warps up visibly! When these overhanging arms on upper part of hexagons start printing, they just warp up while cooling. Then when nozzle comes back for the next layer, it hits the warped edges, pushing filament to the sides and making these artifacts. It didn't break any segments, as they are thicker, but I bet that's what happened in the original print.

    On the new thicker print, the base of the model lifted up from the bed on one side at some point. I was watching the first two layers, so this happened some time later. Gonna try to slow down the print, lower nozzle temp a bit, bump up the bed temp a bit. Will see what happens.

  • Thanks! I'm a beginner, got the printer about two months back. I didn't do any special tuning apart from auto leveling the bed.

    I printed a temp tower with this filament, and it was okay from my viewpoint. Long overhangs were droopy on lower temperatures, and it had stringing from pointy ends on higher temps. I printed a few PETG prints before, but nothing with such fine details as this hexagonal thing.

    Can you point me to some good source of info about tuning? For a noob like me it is hard to tell good resource from slop-compiled one...

  • Thanks again for the valuable feedback! I printed it again with higher temperature, 240. It didn't change much, overall. Same print errors remained, however I got a few less of broken hexagons, so overall the print feels more sturdy.

    Looks like the majority opinion here is to blame that all on wet filament. I don't have the right equipment to dry it, so I'd probably just avoid printing similar parts with this spool, and take more precautions when it will be time for a next one. My drybox spool holder build is almost ready.

  • Thanks for another interesting point. It is faster than you are suggesting. My slicer settings for "external perimeters" is 25 mm/s and for "perimeters" is 40 mm/s. There are no other type of movements on these hexagonal structures.

    I may try slower printing at some point, but it's already a 7 hour print 😄

  • In the oven??? But wouldn't it just melt? I have a gas oven, I don't think it can go too low. But I will look it up. Maybe microwave is a way to go. Thanks for the tip.

  • That also makes sense. I imagine if there is a way to increase adhesion between layers that would help with such problem

  • 2-3 weeks before I put it into a dry box with a bunch of silica gel

  • Help! What is wrong?

    Jump

  • Thanks! I think I unpacked this filament about a month ago, and it was on open air for about two weeks, in 40-50% humidity. then I put it into a dry box with a box of silica gel, and it stays there at about 20% humidity. Until I take it out for a print. Is silica gel good enough for drying? I don't have the drying machine.

  • AI PCs aren't selling, and Microsoft's PC partners are scrambling

    Jump

  • You aren't wrong that these functions don't NEED NPU. But it helps with performance and offloading. What they also doing is opening APIs for software developers to use NPU and built-in models. For example, Adobe and Zoom use it for background filters. Again, with no CPU/GPU load.

    And for your final point - this is not anything new for a company to try selling you a product that you don't necessarily need. Their job is to make it attractive enough for you to upgrade.

  • I think it's just bad marketing. Microsoft, as they often are, just messed up their marketing strategy with mixing controversial and creepy stuff like Recall and actually useful things like local TTS and STT, translation, image recognition and manipulation stuff. All these ML functions offloaded to an NPU are good additions to an OS. Computers with NPU don't have to be Copilot+ branded to be useful.

    Unfortunately, seems that tax software is too complex for enthusiasts to start an open source project. And big tax filing corpos has no incentive to go open source.

  • My big win (in the making) is that I'm going to file my taxes completely offline. Working on the documents in isolated VM, using tax software offline, and sending paper forms wherever I can. Unfortunately New York state is not accepting paper forms, as far as I know...

  • Maybe this is a protection for a situation when you are at your home under the gun point, but they still let you answer the phone and order you to "act normally". Sounds like something from a movie, but maybe this happens in real life too.

    does Reddit block my connection because i use a VPN?

    Jump

  • I think the main intention here is to block the bots. Reddit blocks requests coming from certain IPs associated with VPS and similar commercial providers. VPN services often rent exit servers there. My connection is blocked when it goes through Tailscale exit node hosted on a VPS.

    You can use Tor to browse Reddit anonymously, there is even a .onion address

  • This is great, thanks for sharing! You've got a few useful feedback points, let me add one more: does a provider have an onion address. This allows decoupling of payment from usage. Not a big thing, but good to know.
