I treat this place just like real life. The feed is not tailored to me, so I block lots of stuff. Rude people, people that down vote, narcissists, communities with bad vibes, if I interact with moderators after interacting in good faith, or if I post something I know to be factually correct but get some negative cascade in response I simply block the whole community or individual. I've blocked 200+ users and at least as many communities. I only care about real people that have the decency to interact cordially.

They have all been chased off or banned mostly in response to and protection of this refuge for diversity.

Yeah, then 2 parts and a gap is best. If you are not using Mesh WB, do so and manually mesh stuff. The default export mesh resolution is quite course by comparison.

If you go to the Draft Workbench, there is a special Clone tool there and only there. Clones made in Draft can be resized in the data tab. This is super useful for creating offsets.

What I'm talking about with 'alignment of parts so that they can be imported' has more to do with complex assemblies. If you transform a Part Design body, and then build your thing in multiple bodies, they will be meshed in the local origin of the body's 0,0 coordinate plane. I do this kind of thing a lot. I use a Part Design sketches/bodies/parts workflow almost exclusively. I have to be conscientious of building both parts on the same 0,0 origin.

So with inserts like I was mentioning before, think like the Prusa parts prints for the LCD surround on their printers where they are printing the letters in recessed voids.

Second, – a completely different technique. Think about how you can print a part and setup a void and pause in the middle of printing to insert a bearing or nut, then continue the print, thus embedding the object into the print.

Third, let's combine these two concepts. You print the recessed lettering and a small void behind it, like with the Prusa print plus a void, and then add a pause to the print. Now you take another print that is only the positive lettering and small backing material. You insert this print as you would with a nut or bearing inserted into the paused print and continue the print. You could print the insert at the same time on the same build plate or print it separate in advance. This method also allows you to mix first layer bed textures, filament materials, or even patterns you design into the lettering to be inserted. Like you can print on glass and have gloss smooth lettering inserted into a print on a course bed texture. Or, look up CNC Kitchen's guide on printing nearly optically clear PETG by fine tuning the settings. Then you can create lettering that can be lit from behind.

If you have trouble with first layer crispness, print the lettering face up and use ironing to get a flatter crisper edge.

Someone else mentioned a 0.2mm nozzle. They are not as slow as one might imagine. If you've never tried it, get one. I have a 0.25 and really like it. I use 0.6mm most of the time, but the 0.25mm is not just for cosmetic details. It will really push your understanding of wall thickness and infill strength. With Prusament PC blend, a 0.25mm nozzle is a lot of fun for designing small and putting materials only where they are needed. If you learn to use the Lattice 2 workbench for creating patterns, things get even more fun as you can skip infill all together and start creating more intentional structures in patterns quickly without bogging down FreeCAD. It is fun to transition into design-thinking in terms of single wall shells and connections. That is one step away from an intuitive grasp of flexures and compliant mechanisms. Like my present little Bluetooth enclosure design uses the flex of curved walls and the thickness of material to press a little dome button on the center of a PCB inside. I didn't make any cutouts or separate parts to actuate. It is just the flex of the design. I spent today getting it ready to print with a 0.25mm nozzle and clear PETG too. Anyways, GL and happy printing.

Make two separate parts in CAD. You can join them as separate shapes in a Parts Workbench compound or using the Mesh Workbench tools. Then upload the meshed file into the slicer. Empirically tune the gaps to suit your printer.

Just be absolutely sure that the two parts do not overlap in some intersection. The slicer will absolutely try to print twice in the same place.

Personally, I like to use manual inserts or layer changes. Print your text separately in one color. Recess the text in negative for a few layers. Then add a print pause where you drop the lettering into the designed voids and continue the print, letting the voids and bridging bond the inserted letters.

I was messing with a similar issue with my laptop GPU cover design from a few weeks ago. I wanted the layers to separate between the patterns and how the slicer was pathing . I did a bunch of tests and still need to print a final version but uploading the first layer as multiple compounded meshes is the solution.

If you design the 0,0 location of the parts so that they import into PS already aligned but as separate meshes, you can also use the elephants foot or other unique settings to manipulate how each section prints.

You caught me. I meant this, but was thinking backwards from the bottom up. Like building the logic and registers required to satisfy the CISC instruction.

This mental space is my thar be dragons and wizards space on the edge of my comprehension and curiosity. The pipelines involved to execute a complex instruction like AVX loading a 512 bit word, while two logical cores are multi threading with cache prediction, along with the DRAM bus width limitations, to run tensor maths – are baffling to me.

I barely understood the Chips and Cheese article explaining how the primary bottleneck for running LLMs on a CPU is the L2 to L1 cache bus throughput. Conceptually that makes sense, but thinking in terms of the actual hardware, I can't answer, "why aren't AI models packaged and processed in blocks specifically sized for this cache bus limitation". If my cache bus is the limiting factor, duel threading for logical cores seems like asinine stupidity that poisons the cache. Or why an OS CPU scheduler is not equip to automatically detect or flag tensor math and isolate threads from kernel interrupts is beyond me.

Adding a layer to that and saying all of this is RISC cosplaying as CISC is my mental party clown cum serial killer... "but... but... it is 1 instruction..."

ARM is an older Reduced Instruction Set Computing out of Berkeley too. There are not a lot of differences here. x86 could even be better. American companies are mostly run by incompetent misers that extract value through exploitation instead of innovation on the edge and future. Intel has crashed and burned because it failed to keep pace with competition. Like much of the newer x86 stuff is RISC-like wrappers on CISC instructions under the hood, to loosely quote others at places like Linux Plumbers conference talks.

ARM costs a fortune in royalties. RISC-V removes those royalties and creates an entire ecosystem for companies to independently sell their own IP blocks instead of places like Intel using this space for manipulative exploitation through vendor lock in. If China invests in RISC-V, it will antiquate the entire West within 5-10 years time, similar to what they did with electric vehicles and western privateer pirate capitalist incompetence.

I think the Chinese will do it with RISC-V, or Europe will demand it independently.

We're on the last nodes for fabs. The era of exponential growth is over. It is inevitable that a major shift in hardware longevity and serviceability will happen now. Stuff will also get much more expensive because volume is not needed or possible in the cycle to pay back the node investments.

I'm sorry Chile. My country is an embarrassment of worthless leadership and backwards inbred prejudice fools

The harder they push, the more it incentivises someone else to sell actual open source hardware for profit.

I don't know, often late California evenings here and it gets pretty dead after midnight on the west coast. Some times it keeps up till 1-2am but after that it's something like 50-100 posts an hour for all of Lemmy.
