Banksia wood? (lemmy.ca)
submitted 3 months ago by [email protected] to c/[email protected]

Has anyone ever experimented with Banksia wood for woodworking? The picture used by one random seller online looks pretty interesting. I’m not in Australia, so I don’t really have the wood available and don’t want to spend $$$$ shipping something that might be awful.

What’s a decent blade for ripping accurately? I’m using an old Craftsman 113 belt-driven saw, which I understand isn’t very powerful. I’d like to get nice rips on some 3/4” thick oak. If I can rip thicker stock in the future, that would be great, but as long as I can at least rip thicker softwoods too I think I’ll be satisfied.

I don’t expect to do enough woodworking to worry about a blade made to last through many re-sharpenings; I just want nice rips. Is a $20-30 Diablo from a big box store going to do what I want, or do I really need to step up to the $70-80 range for cut quality? Thanks!

While looking into workbenches, I came across a suggestion that scaffolding screw jacks could be used to make a large vise, but also comments saying that since they’re designed for use on muddy construction sites, the threads have excessive clearance or slop. Is that a problem in practice? I can’t figure out why it would be, since I would think backlash just means you need an extra fraction of a turn when switching from tightening the vise to loosening it. What am I missing?

Is a router the right tool to make long 1/8”-3/16” wide grooves or slots in wood? It seems like I could do it with a circular saw, but only if the desired width matches my blade kerf. I don’t have a table saw. If it is the right tool, does anyone have bits or bit sets they recommend for such small cuts?

It occurred to me that one way to potentially eliminate all filament swap waste from purge towers or Bambu-style filament “poops” is to instead do something similar to a “purge object” or a “wipe object” but where the object is… filament.

The idea was somewhat inspired by Stefan’s video from a few months ago, which first introduced me to the idea of printing filament: https://m.youtube.com/watch?v=CQ-N1fr4N0w

If the purge object is new filament, then you don’t need to figure out what to use it for immediately; you can store the mixed-color filament for later use until you have a genuine need for a color-agnostic or structural object. No more piles of fidget spinners you didn’t really want.

A few other thoughts:

  • The filament probably needs a minimum bend radius so it can feed into an extruder without breaking. One option would be to print a circle or a rounded square / squircle type of shape toward the perimeter of the build volume (potentially multiple concentric ones, or spiralized shapes). Another option would be to print disconnected straight segments.
  • The filament doesn’t need to be printed flat. It could potentially spiral upwards (likely with supports). That could help avoid print head collisions for taller models (in which case you might not want the head to have to get back down to <1.75mm from the print bed). In the most general case, the filament could be printed at arbitrary angles, even vertically, and could start at some height above the build plate (potentially supported by the object itself, for example in an object where color changes don’t start at the very bottom). Maybe the angle could even be optimized to provide the best match between purge volume per layer and volume of new filament printed on each layer.
  • A good solution probably requires a good way to connect multiple segments of printed filament together
  • Mixing materials rather than just colors seems like a bad idea to me (e.g. soluble supports) but I’m going to mention it as a possibility anyway; you could conceive of something inspired by Stefan’s composite material and intelligently organize the different materials within your new filament.
  • You could potentially control the mixes / transition colors that go into your purge filament, or even choose multiple different new filaments for different color transitions. For example, you might have separate new filaments for red-green, green-blue, and blue-red transitions. Maybe you want it create particularly pretty new filament, or avoid particularly ugly combinations.

I don’t actually have a multi-color / multi-filament printer, and I don’t have time to experiment with this (even though the first prototype could be as trivial using a filament shape as the wipe object in PrusaSlicer). I’m mostly sharing this to establish prior art in case someone nefarious seeks to patent something similar in the future (which is also why I added some half-baked thoughts that might make other things become obvious to someone skilled in the art), though it’d be great if the idea is actually good and someone could implement it well. Or for all I know this does already exist.

Thanks for taking the time to read this! Feel free to repost/share/steal the idea if you like it.

What about printing it in two halves the each have a flat bottom? Since the optical quality doesn’t matter, the line down the middle of the lens won’t matter.

Fortunately it looks like the federal courts don’t allow this any more: https://www.ussc.gov/about/news/press-releases/april-17-2024

But of course the state courts have their own separate rules.

I do think it’s important to be unassailable, because it’d be easy to say “the libs are making misleading claims” and then people not paying lots of attention will think there’s a “both sides” situation going on. I’m sure we all assumed it was literally on display as an exhibit; I was mislead. If you stick to transparent, honest language, the “both sides” stuff falls apart.

The MAGAs are unreachable, but the poorly-informed are out there too, and making them easier to confuse (by actually also spewing misleading-but-technically-true things) is not a good strategy.

It was sold in the gift shop, not on display. I know it’s not an enormous difference, but let’s try our best to keep the misinformation just on their side.

Back when I joined lemmy.ca, the front page was full of bicycles, city/province-specific community posts, and others like woodworking This morning, four or five of the front page posts were making fun of some crazy bikini lady(?). I read their “read this first” post and understand why they’re doing what they’re doing, but is there a way to get our default front page to be a bit more…friendly and community-oriented?

Do you want the printer to be a tool, or a hobby (i.e. you don’t mind fiddling with the printer itself to improve the results, you don’t mind spending more to upgrade components, etc)?

If the printer itself is a hobby you can go cheap, but if you want something reliable you don’t have to mess with or upgrade, I’d suggest getting something as nice as you can afford, maybe a Prusa mini or Bambu A1 mini if you don’t care about open source. Also consider something like a used Prusa Mk3.x.

Did they describe the types of user error that could cause this?

CNC Kitchen’s website (www.cnckitchen.com)
submitted 1 year ago by [email protected] to c/[email protected]

For those who haven’t noticed before, CNC Kitchen (Stefan) puts almost all of his content online in text and picture form, not just YouTube. It’s really awesome for searchability and skimming to quickly find bits you’re interested in. I’ve come across it randomly a couple of times while researching things like foaming PLA without even realizing it’s his content, and really appreciate its existence!

Sure. And you can import them too if you’d prefer.

I’ve been really happy with the MK4 kit I built months ago. While I haven’t seen a Bambu in person, I’m pretty satisfied with the print speed and picked up an 0.6 nozzle in case I really want to print something bigger, faster.

I had seriously considered building a Voron Trident, but have no regrets about my decision to go with Prusa. It’s nice having a machine that didn’t require a bunch of tweaking; it was fun to build the kit but now it’s an appliance I don’t have to mess with; it’s almost like my Brother laser. I hit print, it prints*. (Asterisk because I have to clean the bed sometimes, occasionally I make a poor choice slicing and don’t add a support I needed, etc, but these aren’t printer-specific issues).

As far as bed-slinger vs coreXY, even Bambu recently released a new bed slinger, so I suspect the tradeoff is more complex than just “coreXY is better”. The whole “model flings around” just isn’t a problem I’ve seen in practice; maaaaaybe if you’re building exceptionally tall, thin structures that can’t be oriented properly it could matter but realistically most people are going to mostly print relatively small things. Even fast printers are slow; as soon as you use a printer you’ll realize that huge build volumes are absurd because big prints just take soooooooo loooooong even on fast machines. And there’s either upcoming support or existing support for bed-axis input shaping, since the slicer does know the amount of filament it’s extruding and can tell the firmware how much more the bed weighs as the print proceeds.

I don’t think Bambu printers are an unreasonable choice for people, but I think if Prusa is affordable to someone, their products are still a good choice.

Brother laser printers are great.

Check out paragraph 81 of the indictment. One of his co-conspirators was having a discussion with a lawyer; the lawyer said staying in office past January 20 would trigger “riots in every major city in the United States, and the co-conspirator replied, “Well, [lawyer], that’s why there’s an Insurrection Act”.

This was more interesting than I expected. Though they didn’t clarify why it costs $700,000, given the context I assume it’s customers on slower devices/connectivity leaving rather than something like bandwidth?
