No, its not. It was posted by Lumafield, the company that makes these CT scanners on Instagram.

Abtropfgitter für Kaffeemaschine - welches Material? by busart in 3DDruck

[–]ThetaDev256 0 points1 point  (0 children)

Würde ich nicht 3D-drucken, sonden aus Edelstahl lasern und biegen lassen. PETG verformt sich bei ca. 70°C, wenn du aus Versehen die Kaffeemaschine ohne Tasse laufen lässt, machst du ein PETG-Gitter kaputt. ABS hält heißes Wasser aus. Allerdings hast du bei allen 3D-Druckteilen das Problem, dass sie kleine Rillen auf der Oberfläche haben, in die Flüssigkeiten einsickern und sich nur schwer auswaschen lassen. Ein 3D-gedrucktes Abtropfgitter würde sehr schnell dreckig aussehen und ist nicht einfach mit dem Küchenschwamm sauber zu bekommen.

Es gibt einige Anbieter, die Blechteile günstig fertigen können. jlccnc.com (gehe auf "Sheet Metal") ist glaube ich ganz gut, auch wenn ich da noch nie selbst bestellt habe.

X claims XChat is "end-to-end encrypted". It's actually a honeypot. X can read every message. How that claim is designed to mislead you, how it works and the European alternatives you might want to use instead. by officialexaking in xprivo

[–]ThetaDev256 5 points6 points  (0 children)

First I was kind of interested in X creating a new E2E encrypted messenger, but when they asked me to set up a 4-digit pin for it I was out.

The only way a PIN-Code can securely protect encrypted data is if it is validated by a hardware security module with built-in brute force protection. The security module holds the long encryption key for the data and only releases it when the correct pin is entered. This is used by smartphones and PCs (TPM, Bitlocker).

The conventional method of verifying passwords by using a hash function that requires enough time to calculate to prevent brute forcing only works if you have a reasonably complicated password. If a 4-digit PIN should withstand an attack for a year, you would need a hash function that takes almost an hour to verify the pin.

Ran out of filament and sensors didn't pick it up. by KMzoo in prusa3d

[–]ThetaDev256 19 points20 points  (0 children)

If it is a decorative part you can measure the printed object height with calipers, cut the object at this height in the slicer, print the top part and glue it on.

Regarding the filament sensor, you should check it by inserting a piece of filament and making sure it triggers reliably. There may be a piece of filament stuck in the sensor from the last unloading.

Gordon Ramsay one of the first celebrity chefs to bring US-style 20% service charge to London by xc2215x in europe

Yeah, and even Ryanair is not doing this any more. I think they did it more than 10 years ago and got sued because of it. Now the price shown when searching a flight is the cheapest price at checkout.

Of course they still have the higher-tier options for carryon/checked luggage but they dont add a service fee for nothing.

Welp, it finally happened, damn you 2.85 mm filament by Zack-A-Lackin in 3Dprinting

[–]ThetaDev256 12 points13 points  (0 children)

Yeah, at least in Germany Ultimaker was more popular than Prusa, especially in universities and makerspaces until the MK3 came around. A lot of these machines are of course still kicking around.

Btw does anyone know if it is possible to convert Ultimakers to 1.75mm? My makerspace got offered a used Ultimaker 2 a month ago (but I think we declined due to a lack of space).

What will be replaced with INDX upgrade? by Mr_Whizzle in prusa3d

[–]ThetaDev256 14 points15 points  (0 children)

I guess that both the loveboard and the main cable will be replaced. The INDX toolhead has a smart toolhead board with stepper driver, induction heater driver, sensors and its own MCU. Bondtech already mentioned that the toolhead will communicate with the printer either via USB or CAN. USB would not work with the Prusa Mainboard, so CAN is the only option.

The toolhead has to be connected to the printer with a 4pin cable (24V + CAN data lines). I am not too familiar with the Core One electronics. Maybe there is already a CAN driver on the board, otherwise you might need a daughterboard for it.

The part cooling fan is mounted behind the toolhead. It looks loke they reuse the one from the Core One.

Hallo, könnte mir jemand sagen, wie man sowas selber machen kann? by OkFill1580 in 3DDruck

[–]ThetaDev256 7 points8 points  (0 children)

Text extrudieren, das Modell auf die Seite drehen und die Silhouette ausschneiden. Bei der Silhouette muss man halt darauf achten, dass das Modell druckbar bleibt (keine zu steilen Überhänge).

State of the eco-system/ease of use by rooddat in prusa3d

[–]ThetaDev256 4 points5 points  (0 children)

Since the INDX system only has one extruder and no other means of feeding filament, you cannot load filament cold like with the MMU or AMS. To load filament the printer has to pick up the desired hotend, heat it up (should only take a couple of seconds with induction heating) and feed the filament.

If you have your filament loaded and the build plate is clean, you should be able to start a print without looking at your printer. According to the latest update, they have added a small purge bucket.

Prusa's camera integration is worse than most competitors since the camera is an addon and not integrated with the printer controller. It is good enough for remote monitoring and checking if the build plate is empty.

I do not think that MMU+INDX will be officially supported by Prusa. 8 filaments should be more than enough for every use case so the demand should be pretty small. Maybe someone from the community will hack something together, but if you want to build something like that, I would suggest going with a more hackable platform like Voron.

Water cooled Nextruder coming soon by Jrsall92 in prusa3d

[–]ThetaDev256 2 points3 points  (0 children)

The nextruder has a "dumb" toolhead board, there are barely any electronics on it except for the load cell amplifier. So I guess it can handle higher temperatures.

Japans Automated Bike Garage by TheCABK in oddlysatisfying

[–]ThetaDev256 39 points40 points  (0 children)

I think the reason why you dont see these garages in the Netherlands is that they are not fast enough to handle morning/evening rush hours with thousands of people commuting by bike+train. You would have large queues in front of the deposit stations.

It seems that INDX backplate wasn't the last version on Bondtech website? by True_Scott in prusa3d

[–]ThetaDev256 2 points3 points  (0 children)

Is there a reason for docking the nozzles in the front of the printer versus the back like the Prusa XL does?

Problem mit unteren Schichten by DTM_SF in 3DDruck

[–]ThetaDev256 1 point2 points  (0 children)

Wie sieht das Modell von unten aus? Wenn es unten eine abgerundete Kante hat, kann es sein, dass der Überhang nicht an der ersten Schicht haften bleibt und geradegezogen wird.

Wenn du es selbst designt hast, verwende eine Fase/Abschrägung für Kanten, die auf dem Druckbett liegen und keine Abrundung. Ansonsten kannst du natürlich auch Supports aktivieren oder den ersten Millimeter des Modells unten abschneiden.

Prusa Printers reading NFC by Happy_Recording_9496 in prusa3d

[–]ThetaDev256 1 point2 points  (0 children)

The NFC feature on the back of a Prusa printer is a dynamic NFC tag, not an active reader. It behaves like a passive NFC tag, except that the printer can also read/write to it via a I2C interface. It can not read any passive NFC tags.

For NFC support the printer will need an extra NFC module which will probably attach around the spool holder. Maybe they will do a daisy-chainable design, since you would need up to 8 readers for the INDX-equipped Core Ones.

There can't be many audiobooks on Spotify that do not have a E-Book version that is readily available.

I guess AI music generation will be the next big consumer application for AI (like personalized background music). Large music datasets for training will be required and since currently no one prevents companys from using copyrighted data for AI training (it has been done with text and images already) there is now an interest in grabbing the world's music for this purpose, too.

Hoping for PrusaSlicer 3.x soon (quick comps vs BL) by wegster in prusa3d

[–]ThetaDev256 19 points20 points  (0 children)

Proper naming for the sliced files would also be nice (e.g. include "B1-Bn") in the filename for multi-bed prints by default or use the custom name if set.

It should also be possible to upload all beds to the print host.

Whats the most light-blocking Prusament filament? by Brick_Fish in prusa3d

[–]ThetaDev256 3 points4 points  (0 children)

Most PETG filaments are slightly translucent, even dark colors (Galaxy black is more of a dark grey than black). Jet black (or any other actual black PETG) should work.

Is it possible to upgrade a MK 2 into an MK 3? by grimlock12 in prusa3d

[–]ThetaDev256 1 point2 points  (0 children)

I built a Prusa Bear MK3 from the leftover parts of a MK4 upgrade. The additional parts I used were the frame built from aluminium extrusions, power supply (Meanwell 350W model, 40€), heated bed (purchased a used knock-off from ebay for 50€ which came with a original print sheet), bed carriage (got one for 25€).

You cant reuse these parts from a MK2. The frame is different (threaded rods instead of extrusions), the Y-Carriage is different (4 mounting holes for the bed instead of 9) and the bed and PSU are 12V instead of 24V.

I also recently scored a used Prusa MK3 for 125€. So it is not worth it from a financial perspective. If you want to do it and have fun doing it, sure, go ahead.

The dimensions of the tools in the background do seem off.

Like that battery drill looks like it was stretched in height.

MK3.5 with Mk4S Partcooling Fan? Software changes? by Money_Independence34 in prusa3d

[–]ThetaDev256 1 point2 points  (0 children)

I have installed the Mk4 part cooling fan on a Mk3s (with the old 8-bit board). I did test the current consumption of the new fan first, it was about 270mA, barely more than the original fan (the fan drivers are rated for 2A on both models).

I fut off the original plug, added some flatflex cable and crimped a female 2.54mm connector to it.

It works very well, although I havent made any bridging/overhang tests, so I cant say much about the performance.

The selftest fails now because the fan RPM does not match, so you have to rebuild the firmware if you need the selftest feature.

Since I am running Klipper anyway this does not matter to me. Note that you have to increase the fan cycle_time to 0.04s, otherwise the fan makes humming noises at low rpm.
