Designing the electronics layout

My 3D printer is an FLSun 3D Cube. I really like it, I wish I had a couple more just like it, unfortunately FLSun has moved on to delta printers. The electronics aren't well laid out and, frankly used the cheapest options possible. After owning the printer for five years and trying at least three different layouts - just fucking around - I decided to do it up right.

I'm using Tinkercad to design the components and the layout. I have a public Tinkercad project with all the components I use. You can make copies of any of them here: https://www.tinkercad.com/things/edun59eY6AV-components-public/edit

Electronic components for makers

When I'm modeling enclosures for Arduino, I like to have components to work with that match (fairly closely) real life. While the circuit details on some of the pieces might not be completely to the mm accurate, they're close enough to work. Project behind the link.

ISO a delete-in-place javascript library

ChatGPT used to have this, and there was a popular forum that had it (though I can't remember what it was/is), where, when you'd click a "delete" link, the confirmation was RIGHT THERE: "delete" faded out, "OK / Cancel" faded in. In the same space. It was really elegant and unobtrusive.

Does anyone know if there's a library out there for it? I searched over github and google, but didn't find anything, probably because I couldn't get the search terms specific enough.

Do you believe in God?
  • It's logically dishonest to say "There are no gods." How do you prove there isn't something? Maybe you just can't see it right now. Agnostic atheist is the only logical position one could take.

  • What is your "inexpensive" hobby that turned out to be expensive/ you gradually invested lots of money into?
  • Best piece of advice I can give about learning anything (that doesn't involve risk of injury): don't try to learn everything there is to learn. Decide what you want to do and learn what you need to do that. Tell me something you'd be interested in doing...

  • What is your "inexpensive" hobby that turned out to be expensive/ you gradually invested lots of money into?
  • Arduino and hobby electronics. It started out as a continuous loop pad dye machine to save me having to dye fabric by hand, strictly mechanical, but then I wanted to automate adding the chemicals at the right times. Then it was keeping the dye liquor a consistent temperature. Then it was draining the trough automatically. Then I figured out I could design my own PCBs and have them fabricated. It just keeps going...

  • I don't think any of the gravy seals have it in them to actually take on the government. Soon as they see their buddies torn in half by a 50cal it's going to blow the fight right out of them. Sure, sure, it's all "I'll die for my country!" but you put a gun to their head and say, "America needs your life now", not one in ten will have the courage of their conviction.

    I used to doom-scroll to see what bullshit embarrassment Trump was going to put our country through on any given day. Now I'm doom scroll hoping to read his obituary.

    Bacon-y edges

    Ordinarily, I wouldn't turn down bacon for any reason, but in PLA it looks kinda bad. Any ideas as to cause and, more importantly, prevention?

    Hanging my head...well, one of them, anyway.

    I have several skulls around my shop (no real ones, I'm sorry to say) just sitting on whatever flat surface I could find at the time. I decided to mount them so I'd have my flat surfaces back. This is the first.

    Tinkercad and Fritzing working together

    I'm working on a machine that needs five IR sensors to track the edge of a moving loop: position and speed of position change. Since it is 3d printed, the box that'll hold the sensors was designed in Tinkercad, but I also started the design of the PCB that will connect the sensors to the main board.

    Tinkercad enabled me to visualize how it would all fit together: I set the spacing of the sensors and their distance from the base, then used those measurements in Fritzing to design the PCB.

    Is there an AI tool that doesn't clutch its pearls when asked for questionable content?

    I'm writing a fiction story. There are two scenes where a woman is put in danger: one involves an almost-rape, the other the kind of language you'd get from an abusive relationship (in both cases the woman eventually comes out on top.)

    I've never raped anyone or used abusive language, and as an autist I need something to go by if I'm in completely unfamiliar territory. I've been using ChatGPT for inspiration/ideas (not verbatim content), but when I bring up these scenarios, the AI gets all snooty and proper and lectures me on ethics, morals, proper behavior, etc. That's no help at all, as you can imagine.

    So, is there an AI tool that doesn't clutch its pearls when asked for questionable content?

    Getting "pin feathers" on my print

    Ender 3 Pro, Slicr, retraction: 6mm; temp: 215; PLA+.

    The pin feathers usually happen in the upper layers. Cura doesn't do this, but it's so desperately slow as an app (to load, to slice, to preview) that I'm trying Slicr, (which does everything almost instantly.)

    Any advice how to avoid them?

    (The top surface is another issue I can't seem to solve, but one thing at a time.)

    Tinkercad gear set

    Of all the things I've designed in Tinkercad, this project has been the one to get the most redesigns and that gets the most use. It's a gear set to reduce the output of an appliance motor from 1750rpm to ~100rpm, give or take.

    The last set I printed in PLA have probably been run for easily twenty hours in total, about an hour and a half at a time. The early sets were about 30% bigger - for the machine they're made for I can't go any smaller without having to throw in a bunch of extra gears to get all the spacing of the outputs right.

    There's some filigree in the two upper gears. I don't have to put that in there, and no one ever sees it, but I like knowing it's there.
