Claude's been a fun debugging/research tool for various #Linux problems.
Today's project? Running Steam #VR on the Valve Index on #Gentoo.
Here's the various bits of help Claude helped me summarized as a blog post for others to find:

Understood. Maybe a video call at some point? Right now it's anyway holiday season.
Happy holidays and we'll figure something out in the new year 😁🎄
Happy to meet in person at some point if you're interested 😊
But yes I want to put that design over the finish line 😬
Yes, near Geneva 😉
And my background is as a software engineer, so I took lessons from several years of experimentation with a large kossel based frame and made the whole thing work somehow. But it's to get it over the finish line into a proper product that I have trouble 😉
Yeah I know. The guy behind the design has come by multiple times at the workshop. I'm helping him with a project of his 😁 his comment about it though, is that the M4 thread is really fragile.
I may try it, but you can get the pzprobe without the heatsink. I have one, just no idea how to mount it.
I saw it. But I use the swiss3dc.com nozzles and I'm already hitting nearly 50mm3/s.
The nozzle itself is so much cheaper, I don't see the point in changing.
Yes, but the duet smart effector is also the wrong type of effector to mount a toolhead that's rigid enough. The thin pcb will flex if you go at it with any modern print speeds, or if the filament tube happens to pull a bit more than expected.
And yes, I want to stop using under the bed piezo.
No, I don't. I used to use piezos under the bed at anchor points (from precision piezo, but he's not responding to emails anymore).
What I would like is a way to use a load cell or e3d's pzprobe which has the piezo in the hotend. But I don't use revo because it's just too limiting on the flow rate
Mostly how to create a system that stays lightweight, reliable and precise, and incorporates nozzle touch probing... I use G10 as a bed plate for aggression and limit thermal expansion. Benefit is, it limits cost too. But under the bed piezo sensors aren't happy Auth the finished part load 😬
Oh the issue isn't with the large aspects of it. It's with creating an extruder that's minutes on a horizontal tool head. Every commercial extruder at present is based on a vertical tool plate to mount on...
I've already built and sold a few units with 350x800mm build volume 😅
Oh I know. But sometimes bouncing ideas off another human being is better than doing it with a rubber duck 😉
I would love to have an in depth discussion about this, I am still struggling to finalize some design decisions for my large delta design.
What I'm saying is, he's trying. And doing the best of a shitty position to be in. Aside from the printers being oshw, he's still financing prusaslicer for how many companies benefiting?
Is he clear about that? Not really. Can we wish his printers were fully open? Yes. But can I blame him? No.
Blaming prusa for playing that game, and trying to keep being open, is not fair. Why didn't you complain about e3d when revo stopped being open? Or Chinese companies who basically stopped sharing firmware based on GPL code? There's much better placed outrage than this in this industry.
I believe the question is irrelevant. The industry as a whole has stopped releasing oshw files, aside from community projects like voron, ratrig and the like.
You won't find oshw printerd released in the last 3 years being sold ready to print anymore. It sucks but it's the new reality.
And when was the last Chinese oshw printer released? The only one that ever played that have was creality while Naomi Wu was on their case about it. She hasn't been for a few years and everything went closed source and proprietary.
Voron is not a company. You can't buy a printer from voron directly.
Lulzbot is not an open licence either, they may have been in the past, but no longer. They only provide an open hardware assembly instruction manual, which is more about right to repair.
*as open as possible.
I've run into the difficulty of being open while not inviting ruin with a lot of my custom printer design. In the end I settled for keeping my delta extruder secret sauce and making the rest of the machine open source.
The extruder is the one thing not easily copied.
And yet it's still a lot more open than some other players in the field. Bambu, for example, has patented as much as they can on their machines, and made everything proprietary.
Prusa is trying to be as keen as he can without risking his business. It's a hard line to walk. I would know.
Correct. The non open source (i.e. Patented or patent pending designs) will get blocked from sale by filing WTO complaints if there's no license agreement. Typical example is E3D with the Revo CHT where they got a license from bondtech to use the CHT system. No cht clone can be sold because of it.
Which the open source licenses prevented you from doing 😬
And if I recall correctly, the e3d v6 and original prusa i3 designs were also GPL licenses, hence the loss of IP protection for commercial usage.
Yes, well most of the projects use GPL or LGPL or MIT or BSD licensing.
Also prusa has the trademark protection already, that's not the issue. And when we refer to their design being cloned it's more than just "prusa i3" denomination... A lot of clones were created using a different name.
I disagree. Patent law is not dependent on trademarks. The open source licensing model prevents any application of patents on the design, whether software or hardware. Trademark just protect the brand name and image, period. Doesn't prevent copying performance or appearance or functionality
And I think you are missing a fundamental part of how open source is actually opening up your IP for everyone to use. Your name stays on it, but there's no control or restriction on someone being able to use it as is for commercial purposes.
I thought someone working with code would get that.
Is this still true today? Unlikely, to be honest. Machines have gone from being fun projects to being tools that enable other projects in the last 10 years.
That doesn't mean there isn't value in being open anymore. But the commercial aspect has completely changed.
Before people understood the worth of 3D printers, they were very pricey for not much benefit... They were project machines, not tools. Prusa had designed openly in that context.
His designs were cloned and it did result in revenue loss because hobbyists were going for cheap.
The vendors provide exact carbon copies of the original design by the design team. That's cloning being done for the benefit of the community.
Oshw does put the entire IP behind the design at risk of being cloned by others, and there's a long history of this happening,including to prusa designs.
