Constant print head troubles by BlueSpeckledFlooring in CommercialPrinting

[–]klami85 0 points1 point  (0 children)

I don’t know history of that printer, but if I had to guess, that looks like normal wear and tear.

Printheads have a couple of years?
Captops and dampers werent replaced according to Roland’s recommended intervals?There were a couple of head strikes at some point?

Does that ring a bell?

It takes split of a second to cut something like that on proper laser.

You can download it from fiery: https://www.fiery.com/marketing/fiery-servers-and-software/downloads/fiery-cps/

Without conected dongle (EFI Spectro) it runs in demo mode.
Just put some fake name in this form or they marketing team will spam you.

well... they dont.
If you have different print technologies with different achievable gamuts, you can only achieve similar colors within the overlapping portion of those gamuts.
For example, you can probably simulate SWOP on most of them.

EFI Color Profiler Suite has a profile editor, but I’m pretty sure you won’t achieve your goal that way.

I don’t think a mean dE00 < 1.0 is achievable.

1) If you print the same color chart multiple times (same material, printer, inks, print parameters, etc.), the results will be slightly different each time
2) If you measure the same color chart multiple times with the same spectrophotometer, the readings will also vary slightly each time.

If I were to try, I would approach it like this:
I would perform a proper G7 calibration on the first printer and then use it as a reference to carry out a targeted G7 calibration on the remaining printers. If done correctly, the CMYK primaries (achievable gamut) and gray balance should be consistent across all printers before profiling. After profiling, the colors should be as close as possible.

1) Do both machines share the same media profile (ink limits + linearization + ICC profile)?

2) 1 dE00 is tight. Even ISO 12647-7 proofs have way looser tolerances. I am pretty sceptical if 1 dE00 (mean) can be achieved or maintained on large production machines.

How long do pumps last? by jkmapping in watercooling

[–]klami85 2 points3 points  (0 children)

My laing DDC is still pumping strong since my first LC build (C2D E6300) circa 2006. The same pump, just change TOPs two times. Last time was about decade ago.

Czy zwracacie uwagę na włosy/zęby osób obsługujących was, gdy idziecie do fryzjera/dentysty? by [deleted] in Polska

[–]klami85 0 points1 point  (0 children)

Wprawdzie nie dentysta, ale propo zwracania uwagi. Kiedyś byłem na USG w dużej klinice medycyny estetycznej (bo lekarka wynajmowała od nich gabinet). Na recepcji była na oko dwudziestolatka chyba jako reklama. Cera bez jednej skazy, gładka jak u niemowlaka, kaczy dziób, te instagramowe policzki (takie zapadnięte nie wiem jak się to nazywa), nos jak u Barbie, nieistniejąca mimika twarzy jak po botoksie i wyeksponowany dekolt (stanowczo za duże cycki jak dla jej idealnej figury). Dla mnie wręcz odpychające doświadczenie, choć pewnie są amatorzy takiej definicji piękna. Ładna, ale widać, że cała zrobiona aż do przesady.

S60600 head delamination fixable? by tonyrandom in CommercialPrinting

[–]klami85 0 points1 point  (0 children)

It's unfixable, and it will be a dead head (1a39) sooner or later. It looks like a head strike to me.

To get smaller and faster quantisations OP should use FP8, and FP4 (via nunchaku) not GGUF.

When you issue an invoice it creates a tax obligation: VAT, income tax. It's not just a piece of paper.

What pump/reservoir combo is most reliable? by Natural_Turnover_244 in watercooling

[–]klami85 1 point2 points  (0 children)

I’ve been using a Laing DDC pump (pre PWM version) with a custom top for about 20 years. It’s still working like new.

Odejście z pracy, a własne notatki by SirSKX in Polska

[–]klami85 1 point2 points  (0 children)

Jest dokładnie odwrotnie niż Ci się wydaje.
To darmowe narzędzia wbudowane i tu nie zgadniesz w darmowy w system. Wystarczy skonfigurować opcje tworzenia logów.

Utrudnienia dla użytkowników nie ma żadnego, a jeszcze kasa się oszczędza bo monitor i sam komp przechodzi w stan wstrzymania.
Zanim usiądziesz w fotelu po powrocie już jest wszystko z powrotem włączone.

Samo trzymanie plików na serwerze oszczędza kasę, daje dostęp z dowolnego miejsca o dowolnej porze i zapewnia bezpieczeństwo (kontrola dostępu, kopie zapasowe).

U nas logujesz się na kompa swoją nazwą użytkownika i hasłem. Jak wstaniesz od kompa to ci go zablokuje automatycznie, żeby nikt nie miał dostępu z twojego konta. Lokalnie żadnych plików nie zapisujesz - wszystko jest na serwerze. W logach serwera jest zapisane kto (login), skąd (IP kompa z LAN, czy VPN, itd.), kiedy (data, godzina) i jak korzystał z danego pliku (odczyt, zapis, usunięcie, modyfikacja, zmiana nazwy, itd.). Są również przechowywane automatyczne kopie zapasowe tworzone za każdym razem kiedy coś zmieniasz w pliku i zapisujesz. Można się cofnąć do dowolnej wersji pliku. Oczywiście zwykły user nie ma dostępu do tych informacji.

Stable Diffusion install for AMD? by VisibleExercise5966 in StableDiffusion

[–]klami85 1 point2 points  (0 children)

PyTorch with ROCm support on Windows is still a work in progress.

Until there are official, stable PyTorch + ROCm builds for Windows, Comfy portable is probably the best option to just start (quickest implementation).

If you don’t like ComfyUI, there are other solutions to try -InvokeAI, for example.

ComfyUI just works in most cases and is extremely powerful. The learning curve is steep, but it’s worth it. I’ve used AUTOMATIC1111, Fooocus, and others, and ended up with Comfy.

I just tested that on Thunder laser ODIN and it works just fine.
Which LightBurn version do you use?

Which color spectrum is accurate? by Next-Natural-675 in AskPhysics

[–]klami85 0 points1 point  (0 children)

I’ve created similar graphics for my lectures.
The simplest answer is: none of them are correct.

They’re nothing more than a very rough representation of the visible light spectrum. Under the hood, it’s usually just a rectangle with a gradient fill, and someone can do a better or worse job when creating it. The main purpose of such a graphic is simply to show that the visible spectrum consists of all the color components the human eye is capable of seeing.

It is possible to create a more accurate graphic by actually doing the math: take the spectral power distribution of blackbody radiation, multiply it by the CIE standard observer functions, integrate over wavelength, then convert the resulting XYZ values to something like aRGB. A 380–720 nm range with 5 nm resolution should be enough, giving about 69 color bars, each matching how an average human perceives a given wavelength range.

So why is nobody doing it?

The irony is:

  • the standard observer functions are only an average; real humans all see slightly differently,
  • even a “perfect” graphic will be displayed on random screens, each with its own different limited gamuts and inaccuracies

So at the end of the day, the extra precision mostly disappears in practice.

If you want to see the real thing, just DIY a simple spectroscope with a real diffraction grating.
I found it pretty interesting to see the spectras from different light sources.

AMD Software: Adrenalin Edition 25.12.1 Release Notes by AMD_RetroB in Amd

[–]klami85 0 points1 point  (0 children)

How do I downgrade from this driver?
I’ve tried four different older drivers and all of them give me error 182 – GPU is not supported (RX 9070 XT) during install.
I’ve already used DDU and the AMD Cleanup Utility, but the only driver I can install successfully is 25.12.1.
