  • Gptel is better than ellama. Ollama only runs small junk. Llama.cpp is way better because it will split CPU and GPU and run bigger quantized models, especially large MoEs on a 16 GB GPU.

    I started trying to mess with image-dired today for a few minutes to try and get my training images and caption files to sync and scroll, but didn’t get very far before just tiling… such a noob


  • I’ve had all of that from day one with a MK3S+. It just works. I don’t even think about it. Plus your using a slicer that is derived from what I paid for while your money does nothing for me. Adrian Bowyer and RepRap built everything. It would have started in the 1990s if proprietary shit companies like stratasys did not exist. Nothing good comes from selling your right to autonomy and citizenship by inference. The world is falling apart right now because of this exact issue of a lack of big picture ethics. Every decision has consequences. You are either part of the problem or part of the solution. I’m a real liberal. You have a right to be wrong, but I’m still going to call stupid stupid.


  • The ability to filter information using proprietary devices and software in the kernel of all of these garbage devices is the core issue. Trusting the owners of that code is to surrender your right to unbiased and unfiltered information. I am not at all concerned about hacking or security by small insignificant players. I am massively concerned about the extremely powerful using the leverage they have normalized and embedded to become tyrannical neo feudal lords in a fascist society. Google IS the biggest danger by orders upon orders of magnitude. Trusting them is to give up democracy entirely.

    All mobile devices are proprietary. Android is a scheme to make a Linux kernel that has everything ready to deploy except the actual hardware drivers for the processor and modem. Manufacturers take this kernel and add their proprietary binaries at the last possible moment. That source code is not available anywhere. The hardware documentation is not available anywhere publicly. Every device model is just different enough that reverse engineering one does nothing transferable to any other. The level of reverse engineering is extreme and requires destroying many devices using things like fuming nitric acid and fluorine solutions just to have a small chance at reading some parts of embedded memory. These are some of the most dangerous and hazardous chemicals humans make, and you still need xray equipment, special microscopes with stepping automation to stitch images, and a ton of time.

    This is moving to a tyrannical surveillance state of fascist authoritarianism. Open source software is a major front on the line of real democracy. This is a nuclear bomb released on that democracy. You fear the wrong pirates and criminals. The biggest threats always come from within. Trust as a mechanism is fundamentally antithetical to democracy. Everyone demanding trust is a traitor to democracy. Trust is the key of the fascist kingdom. Once that key is held, democracy has failed regardless of whomever is aware of the situation. Democracy requires fully informed citizens with skepticism and the liberal right to decide for themselves even when they are wrong. This is impossible without full access to information. The source of that information cannot be filtered at any level. We already have the narrowest bottleneck of available information sources in the last 1000 years of history. There are only 2 relevant web crawlers. All search queries filter through one or both of these two and the results from these are not deterministic. Two people searching for the same thing at the same time will get very different and very biased results. This is individualized regardless of any protections people imagine they have in place. Outside of the internet there is no real unbiased media. A dozen people own it all. Even the garbage claiming to comb all sources is drawing the line and dictating what is center right or left is. Anyone at the grassroots level is impossible to find because there are no organic unbiased search results. The results are all filtered junk full of agenda and bias.

    This is the real big picture abstract issue in play. When the maga traitors said this was a coup, they absolutely ment that. Mobile devices are all rental garbage someone else controls. Your computer likewise has a secret operating system running in the background that you do not control. In Intel it is called the Intel Management Engines or ME. This started with Intel VPro in 2008. AMD adopted it is 2013. Arm has one too.

    All that is left is to steal your right to have a digital front door by eliminating DNS filtering and all of these devices will be controlled and connected directly by someone else that is watching and listening at all times. You are already in tethers as a digital slave that can be bought and sold for exploitation and manipulation without your consent or knowledge using your digital presence. You have not effectively realized the implications of that surrendering of rights to citizenship with full autonomy. The next step is to redefine the word citizen to be functionally equivalent to slave. “You will own nothing, and you will be happy about it” because if you are not, you will be dead. This is the death of democracy. My words will echo in your head years from now. The dystopia to come is beyond anything you can presently imagine and there is no way to stop it now short of taking up arms and playing Luigi if you are able.

    The consolidation of wealth is what really made Caesar. That was the death of the republic. It was not Caesar. We are all a product of our time and environment. It was the consolidation of great wealth. All that wealth did not give a shit about Rome, it went to Constantinople for better opportunities at first chance because consolidation of wealth is treasonous. It is as it was, just look at outsourcing and off shoring, or the disgusting mismanagement of banking and housing that have made the American worker completely uncompetitive with Asian counterparts at the same standard of living. No, I have no fear of the boogie man or foreign state actors. I am terrified of the criminal that normalizes domestic trust, actively manipulates and exploits me, and steals my purchased property. That is a real monster.









  • It is not the tool, but is the lazy stupid person that created the implementation. The same stupidity is true of people that run word filtering in conventional code. AI is just an extra set of eyes. It is not absolute. Giving it any kind of unchecked authority is insane. The administrators that implemented this should be what everyone is upset at.

    The insane rhetoric around AI is a political and commercial campaign effort by Altmann and proprietary AI looking to become a monopoly. It is a Kremlin scope misinformation campaign that has been extremely successful at roping in the dopes. Don’t be a dope.

    This situation with AI tools is exactly 100% the same as every past scapegoated tool. I can create undetectable deepfakes in gimp or Photoshop. If I do so with the intent to harm or out of grossly irresponsible stupidity, that is my fault and not the tool. Accessibility of the tool is irrelevant. Those that are dumb enough to blame the tool are the convenient idiot pawns of the worst of humans alive right now. Blame the idiots using the tools that have no morals or ethics in leadership positions while not listening to these same types of people’s spurious dichotomy to create monopoly. They prey on conservative ignorance rooted in tribalism and dogma which naturally rejects all unfamiliar new things in life. This is evolutionary behavior and a required mechanism for survival in the natural world. Some will always scatter around the spectrum of possibilities but the center majority is stupid and easily influenced in ways that enable tyrannical hegemony.

    AI is not some panacea. It is a new useful tool. Absent minded stupidity is leading to the same kind of dystopian indifference that lead to the ““free internet”” which has destroyed democracy and is the direct cause of most political and social issues in the present world when it normalized digital slavery through ownership over a part of your person for sale, exploitation, and manipulation without your knowledge or consent.

    I only say this because I care about you digital neighbor. I know it is useless to argue against dogma but this is the fulcrum of a dark dystopian future that populist dogma is welcoming with open arms of ignorance just like those that said the digital world was a meaningless novelty 30 years ago.


  • YouTube has video nerds. There are very few advanced Makers on YT. People like Ben from Applied Science are on the short list. I tried making content for YT a few times but that is like a full time job. YT stopped promoting real low level Makers and community stuff around 2017. Prior to that I had something like 1k5 people I followed on there. When they got integrated into ISP with local caching they had to limit what people watched by promoting a much smaller slice. The result is that now advanced content is not promoted well. YT only wants people that can churn regular garbage like cable TV all over again. So he probably didn’t even know. Still his niche is in transferrable design for a farm and that can be interesting.


  • If I was doing this design, I would build the fins from lower and taper pocket the bottom edge with a 45° pocket that enables them to print unsupported. It is possible to just leave a gap, or make a single wall riser near the tip to anchor the bridge but this will need printer and materials tuning with inconsistent results in my opinion. I think he was mostly showing off the abstract application of an unexpected idea people are likely to watch.

    Ironing is as much about hardness as it is about smoothness. The extended heating will make the lower surface harder and might be workable on your home machine. Your flow rate in slicer settings will be critical for ironing because any bulldozing of material left behind will wreck you. Plus all that extra heat in a solid stack of layers is going to strongly promote warping.

    If you’re really tight on clearance for something like this, I have used typical glue stick. You just add a print pause and either some tape or very carefully apply glue stick just to the overhang clearance with a 2 print layer height gap. The glue may take a day of soaking in water or alcohol to completely soften and dissolve, but that is basically poor-person dissolvable print supports. That trick is really only worth doing for stuff like mechanical prints you want to embed in an assembly with tight clearance. It is a pain in the ass and certainly not a transferable design for a farm or file sharing.



  • Just do small test prints first. For a table saw feather board in PLA this worked but it is length and material dependant.

    Calipers are consistent for the 2.6mm but too dead of a battery to charge the capacitive sensor past around 50mm so the scale shows ~63mm long. I think the optimum angle is around 30° but don’t quote me. I just imported an image of another feather board and used it to get basic working dimensions. You only need to know 1 measurement in a flat image in CAD to calibrate the size for use in the background to draw your sketches on top of. With a table saw feather board, you know the slot dimensions. You could easily screenshot the video’s sketch of the feather pattern here, import that and make a copy at any scale in FreeCAD. Mango Jelly has YT vids about this if you need them.


  • It is an interesting approach to use feather fingers to hold a lid. That one has never occurred to me in design, but I loath thick useless walls like this.

    He kinda touches on the way sharp corners are an issue because of the overlap in the extrusion diameter at the direction change. The overlap in circles is ignored in the slicer so there is always some amount of over extrusion in corners without a built in radius matched to the tessellation resolution and step accuracy of the machine.

    Personally, I prefer to make a slightly larger clearance for such an interface. Then I use a small round dimple between the parts in the center of the long wall. Any long wall will have some flexible compliance at the center. I use a small 2-4mm diameter dimple that is padded/pocketed 0.5-1.0mm with a similar tolerance to the part. The subtlety of this feature is far less likely to disturb the outer part perimeter wall smoothness. The trick is to design the positive dimple pad with a closer tolerance to one side so that contact pressure is held to prevent looseness.



  • Fuck smart phones and neo feudalism. This is theft of ownership with a criminal complicit government. I applaud all Luigi’s these people deserve it. These are the killers of democracy. If your device only runs factory filtered stalkerware garbage, all democracy is dead. All information is easily filtered by this proprietary shit. Freedom of the press is a bullshit tiny niche of the broader requirement for a fully informed public. The fucking “press” is bullshit to highlight. You must have fully informed citizens and you may not choose how that information is shared or disseminated between citizens. This is not democracy. People are so fucking stupid.



  • Their website has been janky. They have done stuff that is likely related to poor configurations of the server but appears to be exploitive. Their site hasn't had very good features for search either. Their search results are generally garbage in an authoritarian like attempt to salt your query with unrelated irrelevant garbage to milk ads. When they are unable to serve ads, they have tried to block access in the past. They seem under funded and likely have a mess of unmaintainable spaghetti code because when they make changes other stuff seems to break often. Downloading files from such a place is likely to be a major security risk.

    Additionally, all of these file sharing websites are kinda a beginner’s thing. They are only really useful for trinket type sculpted objects. When it comes to functional prints, there is a lot of subtle details required for proper design. You will quickly learn that fasteners, and print tolerances required to replace metal fasteners is very print, material, and printer specific.

    I know my exact tolerances in every orientation on my Prusa. When I design, these elements are built into that design. I do not care about calibration. Anyone that obsesses with calibration is doing so in order to transfer designs between machines. If you make your own designs you just need to dial in the tolerance locally. If you really need a 9.95mm part dimension with a 10mm slot in some object, it is extremely easy to do in CAD. Just print a unit test of a slice of the object in question in the same orientation and manually measure all relevant dimensions and tolerances. Let’s say you measure 9.98mm when you dialed it to 9.95mm. Which side needs to be adjusted might be a factor too. All you need to do is go into the CAD and change the dimensions to 9.92mm with the change oriented correctly.

    By design these are ultimately precision machines without accuracy. The 0,0 home location is always different, but all motion is relative to this location. Calibration is trying to create transferable accuracy in a precision system. The deeper you get into this, the more it becomes an issue. Tesselated object files are also an extremely poor way of transferring designs because it bakes in the precision versus accuracy bias.

    If you are unaware, the issue with files needing tessellation is because of π being infinite and all computers truncating infinite floating point values.

    A slightly better solution for small file sharing is to post STEP files. These are the real dimensions with π as generated by the CAD hierarchical tree, but without the full tree. The STEP file can be imported in CAD and further refined through new operations and importing edges from the STEP file. However, if you go down this path, you will likely find that only beginners and extreme amateurs seem to share their designs even at this level of sharing STEP files or even the large CAD files too.

    One of the most critical advanced CAD skills is knowing where to place an object’s origin and how to dimension everything relative to critical dimensions. This gets into the topological naming issue of how CAD works under the surface. Basically there are a ton of ways to do CAD wrong. There are many CAD operations that exist for very specific niche case reasons, but are never supposed to be used within the main hierarchical tree. If this is done wrong, it will create multiple stacked references to truncated π and this will break the CAD part every time, especially when making any further modification. I often have this happen at a couple of stages within my own very complicated designs. This is very typical in a CAD design workflow. The solution is to stop and rebuild the entire part from scratch while building the proper order of operations or a better origin for the part. I usually rebuild a part at least once or twice before printing complex stuff and assemblies.

    In the past I tried printing stuff from places like thingiverse, but it was fiddly and nothing worked very well. I started importing them into FreeCAD and just rebuilding them with the part as a reference, but even this sucked. My only use for these websites now is for ideas I might integrate into my own designs. I can make anything in CAD properly and faster than I can print the whole thing twice. That is the full learning curve of 3d printer file sharing. It is also why selling files is not really a major business thing that takes off. That would only be possible with accurate machines. Precision is cheap, accuracy is not.
