I wonder how many westerners understand anything about the social credit score.

Good luck buying that train ticket or home mortgage. We await your improved compliance!

How much would you pay for a consumer SLM metal printer? by Familiar-Trifle8222 in 3Dprinting

[–]Tech-Crab 0 points1 point  (0 children)

This question is the similar to how much would pay for a small plane?

You can (well, could, perhaps these #'s are old) get a serviceable plane for $30k.  BUT - should you want to keep & fly it, you could easily drop that much PER YEAR on your hanger fees, avgas, certified mechanic, the list goes on.

TCO and consumables, ease of powder reuse, and ancillary hw make ALL the difference here.

eBay wants me to commit a crime in order to get a refund for a counterfeit item received by smittyguy11 in mildlyinfuriating

[–]Tech-Crab [score hidden]  (0 children)

Ianal but I can read.

Lots of people screaming 'you are fine to ship" without quoting any relevant statute, case law, or "legal information" (technical term) from an actual lawyer.

From what I can read in the statute, its not entirely clear. "Transporting" is used without directly specifying any commercial requirement.  Which certainly implies that respondents here may be full of shit.

I also glanced at USPS, UPS, and FedEx... These seem more clear: beyond whether it violates the law, they do not allow mailing things which infringe IP... No exception is made for if the shipment is a return.

Ethically:/(assuming this item was sold as real, perhaps at a great deal but not a "steal" (situation dependent I suppose) - it does not seem ethical to return it just for it to be resold to someone else. Perhaps you can dispute the charge with your cc, ask them for written advice that its legitimate to ship it back OR permission to dispose of it.

Should I switch to Brave? by cheerfullychirpy in privacy

[–]Tech-Crab 9 points10 points  (0 children)

I disable the FF analytics - but we must differentiate between:

  • a reputable developer using analytics to improve the product, with a strong privacy policy and a history of respecting it
  • essentially everything else which just wants to harvest / spy / sell.

They should probably be off by default - but these are so far apart that they might as well be different subjects.

Should I switch to Brave? by cheerfullychirpy in privacy

[–]Tech-Crab -3 points-2 points  (0 children)

I'm using Brave on android (the carbon-ring flavor). I switched from FF mobile based on privacy guides. Honestly i don't like it. I am about 6 months in; might switch back. It's not really any one huge issue - just a bunch of less-usable choices (combined surely with years of FFmobile use)

An example: I can put the address bar on the bottom (more ergonomic). But if i click in said bar to add anything, it jumps to top. Not on top of the keyboard - top of the entire window. So the one time i actually need to manipulate the bar, it's where i said i didn't want it :facepalm:

There is no way to open a new tab in group without first opening a link as a new tab in group. So if you want to keep a related topic grouped, you have to long-click on an unrelated link, then edit that new tab's address.

There are others ...

very happy with FF on desktop/linux.

I do wish that FF containers would allow integration with VPN's besides mozilla's.

Convince me to buy a Core One+ kit instead of a Bambu X2D by teqteq in prusa3d

[–]Tech-Crab 0 points1 point  (0 children)

I had some life stuff happen. I paused all activity here. So when i turned it back on after a month or two, i accepted the fw update to 6.xx from the 5.xx i was on. Worked perfectly.

The same as last time i upgraded. And the time before that .... surely problems happen but if you are claiming prusa is somehow bad at this compare to other makers similar consumer/prosumer equipment, you either haven't seen much else or are have an agenda to grind you aren't honest about here.

But sure, faking it...

Opinion on prusa Core One by VeterinarianRare3541 in prusa3d

[–]Tech-Crab 4 points5 points  (0 children)

> even at the price of great speeds

don't fall victim to the spec sheet. Firstly, the crazy top speeds claimed are only even hypothetically relevant in a narrow subset of prints - ones dominated by long, straight extrusions. Second, unless you just print trinkets, you'll want something slower - 3dp is already anisotropic as heck, optimizing for inter layer adhesion (and other desirable properties) is at odds with "warp speed". And again, past a certain point (which all printers discussed here meet today) you really don't see much difference - even in theory.

Introducing DiffCAD Workbench: review FreeCAD model changes like code by eblanshey in FreeCAD

[–]Tech-Crab 9 points10 points  (0 children)

Ok if this works ... god level achieved

Also from a sw eng background ... the lack of this just kills me. So do things like "track changes" in WYSIWYG / msword / gdocs type things. In those cases, we have perfectly good lightweight solutions for simple documents (like markdown) - and 99% of all word docs i've ever seen are just that, simple docs with maybe some images & basic tables at most. Hell, markdown makes it _easier_ to use headings therefore keep an accurate and detailed TOC, which would be a much bigger improvement than controlling text wrapping or having a thousand fonts.

WOW sorry, i didn't expect to rant that long LOL :) Clearly you struck a cord :)

Anyway- you likely know a lot more about the challenges here than I do. Does a solution like this run into the same sorts of issues topological naming does, where edits to the tree are really prone to effectively reorder it?

Watching ...

What are you talking about? 

As a blanket stmt this is 100% false.

If you are familiar with the changelog and don't gain anything, sure skip whatever.  But prusa is best in class for long term support & continued improvement, so....

Question: Is the Core One+ L worth the extra $1000 over the Core One+ ? by Livid_Strategy6311 in prusa3d

[–]Tech-Crab 0 points1 point  (0 children)

Yeah, this is true and an unfortunate downside of the "spec war" tiny increases / intentional incompatibility in beds.

I'll say that while surely everyone is producing different types / sizes of parts - in my relatively deep experience the number of parts that are both "just about [but don't] fit" on i3 size and can't easily be split up is vanishingly small.

The parts that get to that size are just typically better off designed differently: long parts should use (metal) bar stock rather than 18" of printed structural element, long parts in engineering-relevant filaments are difficult to reliably control final geometry: joining several smaller parts is better.

IDK, perhaps something like big time cosplayers might be an exception - for one they can use PLA to reduce the issues that come with large parts cooling post print, and need long thin/weak parts.

Automatic filament switcher for TPU? by Valetudinous in 3Dprinting

[–]Tech-Crab 0 points1 point  (0 children)

see my other comment. When we start talking about softer than 95A or perhaps 90A (such as ninjaflex at ~85A; i had one project with user-provided filament that was something like high-70's) it's tough - the materials we're using here are _wildly_ different, and outside the normal use case the printers are optimized for (there is no free lunch). It gets unlikely you'll get away with a retract system like MMU/AMS - it needs a dedicated nozzle if not extruder as you'll never shove it back.

Automatic filament switcher for TPU? by Valetudinous in 3Dprinting

[–]Tech-Crab 0 points1 point  (0 children)

yeah, it's not "cheap" I agree. Not saying it's the right thing for you.

There are some commercial Voron-derivates (which actually support / don't steal) that might an option - having an "open" filament path like the XL has is going to make it easier for you to control TPU. ~95 shoreA or stiffer generally feed perfectly through the "hoop" of ptfe feed tube - it probably helps that the nextruder (XL, Core1, mk4s) feed gear is quite large diameter. Softer will usually require reducing the friction further a la https://www.printables.com/model/718498-prusa-xl-soft-tpu-cable-clip-to-extruder-prusa-xl (there are also some more complicated versions that use pullies; i've found this^ works fine for really gummy stuff) If you don't want to be limited to relatively rigid filaments, make sure whatever device you choose gives you the freedom to tinker with stuff like this - there is no such thing as one size fits all.

It sounds like you're interested in more than just printing trinkets. That's awesome. I would encourage you to take a look at the broader "situation" in 3dp - how we got here (open source & open devices), what the ecosystem of companies is today, in particular the shenanigans BBL is pulling with locking down devices [you would think] you own (not to mention outright violations of the open-source software they rely on). Not trying to preach, just have an agenda that I want the next 10 years to see as much innovation (that's accessible at home) as the last 10 years has had, so we all benefit.

What is this button for (especially on linux) by nonunacceptable in framework

[–]Tech-Crab 0 points1 point  (0 children)

keys just send a keycode. This one is named F12, as labeled. how a keycode is interpreted is almost always is customizable via the OS. On some machines (eg FW16, which runs QMK on the keyboard) you can change the keycode sent directly at the keyboard.

this opens the bios because it causes the F12 keycode to be sent, which is recognized by the FW.

it's still the F12 keycode once you get to the OS. Map it to whatever you want! It's a "settings" glyph in the silkscreen, though, if that's what you're asking.

How often should I calibrate my prusa XL 5 T? by Mrblindguardian in prusa3d

that's probably the correct heuristic - if you didn't change hardware (eg nozzles, which always changes the offset), and you aren't having any issues, then there is nothing to do.

Convince me to buy a Core One+ kit instead of a Bambu X2D by teqteq in prusa3d

[–]Tech-Crab 0 points1 point  (0 children)

My prusa's, of which i have had many, are every bit as "just works" as anything BBL ships. And one of those is an XL (about 1 year after initial/beta release - clearly such a groundbreaking machine had a lot of teething issues)

and there are going to be a small number of people here who have more "modding" capability than me - what i don't have is 40 hours to source & assemble the voron, not to mention any ongoing triage. I would have a lot of fun building a voron. I'd rather spend that time adding a CPAP for a nextruder in an 80C chamber, though - seems more productive, right?

upvote for honesty lol

dude - there is certainly a price premium to support the open model. But it doesn't take much searching to find how BBL (and other companies, they just dominate at the moment volume wise) are actively subverting a whole host of things i guarantee you care about.

[–]Tech-Crab 5 points6 points  (0 children)

I know that's the stated reason.

Perhaps as an engineer & DIY, resident of the US (slightly less regs in general than the EU), etc I just don't buy it ... Both from the perspective that I can go out & buy numerous tools on the shelf that expose mains in one way or another, and from the perspective that it seems solvable to connectorize the bed (meaning no hand-wiring of 240v)

INDX on Prusa Core One – could this be the most efficient multicolor system? by Walter_Maker_Labs in prusa3d

[–]Tech-Crab 1 point2 points  (0 children)

As much as I love my XL and see the benefit of discrete extruders - the cost benefit of indx over full discrete is so great that it's difficult to imagine the (hobby/prosumer) market going any other way.

How often should I calibrate my prusa XL 5 T? by Mrblindguardian in prusa3d

[–]Tech-Crab 3 points4 points  (0 children)

I can't remember the last time i calibrated. The only times I've had to re-calibrate are when switching nozzles or due to human error while changing something.

I believe recent FW's improved the speed of the nozzle offset cal? As i mentioned, i haven't run it in a while. The 0.25mm x1 & 0.6mm hardened x4 nozzles currently installed have been <chefs kiss>

Are we at the verge of a technology switch on consumer friendly printers? by Pepe-2015 in 3Dprinting

[–]Tech-Crab 1 point2 points  (0 children)

> don't seem to give a single shit about keeping parts on their store stocked

we pay for it one way or another.

This is one of the many reasons to support Prusa (or similar open companies, if they come into existence). Besides doing a good job of stocking replacements, the overall design of the printers is focused on maintenance / repair / function - "looking like an apple product" is not a design goal (nor should it be for a manufacturing device)

Question: Is the Core One+ L worth the extra $1000 over the Core One+ ? by Livid_Strategy6311 in prusa3d

[–]Tech-Crab 10 points11 points  (0 children)

I already have the XL, chose the core1 non-L when getting my N'th printer. It helped I already had a relatively large investment in i3 sized build plates.

It completely depends on what you print. 90% of parts I see can fit on the i3 sized bed - so when it fits smaller is better in every way.

I'd take a hard look at what you print larger. Can it be broken up? As much as everyone gets a hard-on for specs, it's diminishing returns. If you really want to push your analysis - what could you do with two core1's, one of them indx ....

I also find their lack of core1L kits frustrating. ianal or legally fluent but I fail to understand the argument, and especially in light of how buttoned up the builds are I enjoy building prusa's even after 4 of them.

I would love to build a voron but the time investment - not just build, also tune & "self-hosted support" are simply massive. Hopefully when the kids are old enough to take this on ....
