  • Spotify and other such services almost certainly sound worse because they are compressed. But it’s not really a like for like comparison with vinyl. Spotify is streaming audio for people who want to play music casually in cars, earbuds etc. It offers convenience, not perfect sound fidelity. FLAC / CD on the other hand could be compared to vinyl and would win hands down for better frequency and range. The only reason they wouldn’t is if the CD master sucked and the vinyl master didn’t.

    And vinyl is very lossy in its own way. The (digital) master of each side undergoes dynamic range & frequency compression to fit the limitations of the format (e.g. to reduce sibilance, track width). Then the master is cut into a lacquer disc from which a “father” is made, from which “mothers” are made, from which stampers are made and from which the vinyl record is made. So the vinyl in someone’s hand is a copy, of a copy, of a copy, of an altered digital master. The stamper too wears out so if someone is unlucky they get a pressing right the end of its life. And playing the disk can cause wow, flutter, distortion and general wear & tear can cause hiss, pop, dullness and scratches.

    So vinyl will never sound better unless it received a better master than other formats.



  • I had the misfortune to have some PLA snap just before and after the direct drive in my Bambu P1S and it took ages to get it out. I think age and moisture can affect filament, especially it blended with wood dust, sparkles or something which undermines it even further. I’ve resorted to packing my AMS with silica beads to hopefully mitigate for the issue and I threw out the filament that caused the issue. Ironically this is one of the few places a bowden extruder is any benefit - if the filament snaps just push it from behind through a heated nozzle until the blockage clears.


  • Been reading there’s too many complications (different state for one, more red tape) for the value. They’re going for the low-hanging fruit right off, liquid money like bank accounts, working their way up from there.

    I think it would make sense to seize & sell assets in New York but I bet there are some really complicated ownership deals on his properties and some will be laden with lease agreements, debt, mortgages etc. They might see Mar-a-lago as having a clean ownership making it worth the effort of going after.


  • Scotland absolutely fucking hates Trump so I think they would be very happy to overcome the legal friction with the sale of his Scottish courses if it came to that.

    But I think most likely she’ll target US properties & assets first for obvious reasons, in her own state first but anywhere is fair game - a judgement in state of New York is enforceable anywhere even if there are requirements and legal effort to “domesticate” it to target state to enforce it. I will be very amused if Mar a Lago is seized though knowing Trump he’ll try to pretend the thing is his “homestead” despite it having non-residential status and he himself only living there through a loophole.











  • Wouldn’t the problem be that you’d still have to remove the print, wash it, empty the vat, clean the vat & build plate and only then could you put the print back in and then fire up the UV. Meanwhile you won’t be using the printer for anything else. Maybe it’s easier to just buy something that can wash & cure separate to the printer or leave the print out in the sun to cure.

    BL touch works great but you need to get the Z offset. Then you can just G29 before the print or whenever and it works great. I hate manual levelling and these days there isn’t much reason for it. I’ve just upgraded to a Bambu P1S and levelling is even more straightforward since there is no Z-offset since it uses the hotend itself to probe.

    In my Ender 3 Pro I found tightening the screws too much made the bed bow, so I loosened them until they were just firm but not forcing up the corners. I also replaced the default springs with stiffer ones so once set they stayed set. I also built a custom Marlin firmware and I changed the bed mesh algorithm to probe more points and use a more sophisticated algorithm to compensate for levelling. This was with a Bigtree 1.2 board which barely had enough memory for the firmware but I made it work. After that I really didn’t have any issues. Biggest pain was dialing in the Z-offset on the BL touch.


  • I’m sure it’s easier for them in a sense. I write software to control cloud based devices that are not adjacent to the caller and they use message based comms. But it’s also an unnecessary overhead to upload a 70Mb file to the cloud and back down again. If I were writing this software I’d consider some shortcut mechanism where the send file action could be sent to the printer directly and only fallback to cloud if that was not possible. If for no other reason that saving myself money and general responsiveness. I’m sure it would be achievable by doing a UPnP scan of the local network and allowing the PC to talk to the printer if it possesses and sends an API key - much like Octoprint works. Also, local network probably helps for the camera which could just blast a feed out on UDP.

    I’m not sure it helps them “steal” models because they probably have 100,000s of models passing through their system every day. It would be a wall of noise and random junk. And these aren’t models in the CAD sense, but some STL meshes and print settings. It does give Bambu information about what filaments people are using and in what quantity, the frequency they print as well as geographic location. That might be useful for marketing. If a government was interested in a particular user, they could also see in retrospect what they were printing. e.g. if someone were printing gun parts then maybe there would be evidence of that in the cloud.
