Kinda sounds like combine infill layers in prusa/super slicer, that setting will have it do the perimeters as per normal but do infil at 1/2/3 etc layers, so 0.2 layers would get infill every 0.4 at 2, so it’ll print the perimeters and anything that can’t be merged, go to the next layer and do the perimeters and chunky infill, I use it to save time and I haven’t noticed much difference in functionality.

Yeah I recall the USAF deploying a ps3 cluster years ago

I remember one of my engineering profs describing Midgley as the most environmentally destructive organism ever, Dude also was involved in the creation of freon.

Could have a bot that links to a git wiki, or even just a sidebar with knowledge base stuff would be nice for that.

I’m a data engineer/architect and it’s the same over here, I get asked constantly “how can we stuff AI into this solution?”, never “should we consider using AI here? Is there a value?”, my view, people don’t understand their data and don’t want to put in the effort to understand their data and think that it’ll magically pull actionable insights from their dataswamp, nothing new, that’s been a constant for as long as I recall.

Like I totally understand the draw of new and exciting, but there’s so much you can do with traditional analytics, and in my view you really need to have a good foundation before doing anything else.

Totally get you, I swapped my prusa’s hotend for a stealthburner as well, they’re super nice to service, especially with the 2 part PCB, but having the entire assembly mounted from the front is fantastic.

Stealthburner ended up fixing your clog issues entirely?

Fingers crossed. There’s hats you can get to power the pi off of printer’s 24v supply, considering doing it on my klippered mk3s and switch that over to using a SBC instead of the laptop.

If you can swing it, definitely worth printing a spare set for the stealthburner + cw2, just in case you crack anything during assembly.

You’d think right, anecdotally when I was meaaign with undervolting on my desktop, you’d get instability or crashes at the limits without useful errors. Could think maybe the processor isn’t getting enough power and that’s causing instability? Found a klipper thread that about losing connection with the mcu which totally can show up as an EOF error.

How are you powering the pi itself? Wondering if the wakeup draw from your screen is enough to make it unstable, 4 I believe having higher power drawn than the 3 if you’re using the same power supply. Pi isn’t oced either?

Quick Edit: I run my v2.4 on a lepotato with oodles of usb attachments (camera, multiple mcus, wifi and a screen. Replacing the mcu connections with a usb-canbus bridge when the heatwave ends) but with it connected directly to a meanwell 5v5a PSU into the gpio header, have never had communication issues to the octopus pro I use. Skr mini on the other printer is connected to a laptop host so it definitely has enough power, did have some odd issues with the skr mini and having an accelerometer connected to the spi header on boot and separately the 24v supply becoming loose that I fixed by crimping ferules onto the supply wires when I added a molex connector to make taking the printer out of its enclosure easier.

Yeah that’s how I did the mockup, I use superslicer on one printer and prusaslicer on the other so was hoping I could do something that’d be able to port between them easily.

On that thought, superslicer being based on prusa slicer, wonder if I could just import the project like I’ve done with filament profiles. Thanks!

Yeah I used inkscape for the image dxf, good thought on the text. I’ll try it in freecad again, had it die on me a few times so I started looking into alternates, thanks!

I’ll give that a try, thanks, figured it’d be something straightforward!

I have a large chunk of my colleagues who have little to no experience using CLI tools, and totally have found the last part to be true. In fairness, documentation is all over the place quality wise (I generally find Microsoft’s useful but I’ve totally had issues in the past with undocumented or vaguely documented features/dependencies). People will google their issues, and increasingly I’ve found it doesnt point you at the documentation directly, instead stack overflow or medium pages.

I feel like there’s definitely some conceptual… Stuff for lack of a better word that’s an issue, I’ve seen a number of people focus on the execution instead of trying to understand what’s the issue and define it logically, when pressed they struggle to explain.

Super regional, remember learning 15$ in French class but using $15 everywhere else because I’m an anglophone. Personally, as someone else said, it’s a unit, totally makes sense treating it as such and I do tend to use iso currency codes when talking dollars because I’m Canadian, 40 USD is 54.75 CAD, 40 CAD is 29.23 USD, if I don’t specify that it makes things look way more expensive comparatively.

If you want a SBC, a lepotato works really well, supposed to be more performant than a 3B. I used as an alternate to a raspberry pi for a klipper setup, running armbian on it now.

There are updated versions of it as well if you need more performance, but they’re cheaper than an equivalent pi and importantly, purchasable which was an issue when I was putting together that printer.

I actually really like Metro, live tiles are criminally underused and imo it gets a lot of hate becauae of how microsoft pushed it in windows 8, but for a touch interface it’s clean and really nice to use. Loved the sideways laid out apps too on windows phone and windows rt, wp itself was actually really nice to use and I actually kinda miss my lumia 1020

Generally lubricate every few hundred hours, however you really should consider condition based lubrication over time based, over lubrication is actually a really common failure mode for rotary bearings and would not be surprised if the same is true for linear bearings. 50km intervals sounds like an order of magnitude too frequently based on what I recall from Thompson, yeah the bearing type, loading, cleanliness etc all play a part, but their examples are in the hundred of km range, not tens.

Are you ensuring that you’re actually getting grease into the bearing as well? The MGNxxX bearings are usually sealed, you need to get past them to actually lubricate as you want to expel the degraded grease. Myself, I do some white lithium via syringe and then machine oil on the rails, and even that’s probably excessive. Moving the bearings by hand along their length of travel will give you a feel for them as well, there’s a lot more you could do but I’ll be totally honest that it’s probably not worth doing, consequence of failure is basically nothing in the hobby space (no risk of injury, low costs, no impacts to business, basically if a bearing goes you’re out what like $50? and an hour)

I can’t find much literature about it, did find this safe handling procedures from UNSW Sydney if interested. I’d say if you’re concerned, don’t use it. The fibres themselves to me are a concern when out of the polymer, so take precautions when sanding or cutting, glove up and wear a mask + eye protection, probably should consider wet sanding too to reduce airborn dust. Print in an enclosure with ventilation, same precautions you’d take for abs and nylon, you don’t want to be around that when it’s printing. As I said though, if you do have any concerns, don’t use it, there are matte finished filaments if thats the look you’re going for.

What was CNC kitchen’s concerns? As above, personally I’d be concerned while disturbing the plastic through printing, cutting, sanding etc, just handling it wouldn’t be on the top of my list unless the plastic has degraded or been damaged in some way, pretty much how I’d treat anything with fine fibres or particles in it.

At the end of it, I’m just some guy on the internet, if you have concerns, don’t risk it. If you do decide to use it, treat it with respect like you would anything with fine particles or fibres.

12 dB is a pretty decent reduction if your goal is hearing protection, 100->88 is also bringing it to something that absolutely needs hearing protection to something that’s borderline acceptable for an 8 hour shift depending on your local laws, mine say 4 hours but still, way more comfortable to use.

I have an nvme enclosure with a 256 gig drive in it, I think I partitioned a quarter of it for ventoy, rest is for regular storage. It’s really nice to have if I do family support, have any iso I need and any utility I might need on top of that. Is it overkill for my needs? Yeah, but it’s nice to have and I didn’t go for anything fancy, just a cheap crucial drive.
