Kann man eigentlich mit PETG Filament auf PETG Platten drucken?
Ich habe viel Zeit in diese Frage investiert, die kurze Antwort ist - Ja, ziemlich gut sogar!
https://printys.net/2024/05/04/printing-with-petg-on-petg/

Eine durchsichtige PETG Platte in einem 3D gedruckten Rahmen. Auf die Scheibe ist ein Text gedruckt: "Transparency is" und ein Symbol für einen Schlüssel (Key).
Auf zwei Werkböcken liegt eine runde durchsichtige Scheibe aus PETG. Darauf ist auf der Unterseite in Haken aufgedruckt, daran hängen an einer Bandschlinge Hantelscheiben mit insgesamt 12,5 kilo.
Die Hantelscheiben an dem gedruckten Haken, von oben gesehen.

@LittleJoeMuc fyi, I know people at Prusa and made sure they're aware of it. Maybe we'll see future enclosures with a nice print on the sheets?

I left my 3D printer unattended for a couple of hours, and it completely screwed up and the extruder got completely encapsulated in a 1cm thick glob of PLA filament. This is what it looked like after half an hour of delicate unglobbing. Another half hour of cleaning and reassembling and it was working fine again. Not sure what went wrong - PETG builds are nearly always perfect, but I'm building something that should be a little more flexible, hence the PLA.

RichiH,
@RichiH@chaos.social avatar

@saustrup PETG is more flexible than PLA? If some PETG is stuck in the hot-end path and you push PLA through it can glob up heavily. Cold pulling with PETG or PC might help.

I've had so many issues with my Anycubic resin 3d printer, and for this and other reasons, have been considering an FDM/filament printer.

Is it fair to say that most printers in the $150-300 range are crap? I just saw on one of her LED necklace tutorials that @geekmomprojects uses the Prusa MINI+, and it seems like a good number of makers speak highly of that brand, so maybe that's where I'll look. But any tips on where else to look/stay away from are appreciated!

RichiH,
@RichiH@chaos.social avatar

@yelof @geekmomprojects there's more modern, quicker, cheaper, cooler, etc than Prusa. But they have a long history of "just works" with support for the machines a decade after release.

Did someone ever try to use a 3D printing pen to fill-in those nasty seam lines that a printed 3D model has on each layer? Usually I sand them away after optionally filling them with super glue and baking soda. I wonder if closing the gaps with a 1.75 mm filament compatible pen could be an option, as I could use the same filament used to print the model.

RichiH,
@RichiH@chaos.social avatar

@bricks orca and prusaslicer are able to hide seams now. Works quite well.

Big thanks to @jcorbin for walking me through a ton of finer points of I've made my first model!

It's a little late for indie bookstore day but these are bookmarks for my local bookstore.

I'm testing a print in the only color PETG I've got, and will try a 2 color PLA in the morning. I think the inset one would look really good with the letters (and bottom of the bookmark) in black with a white top. 🤔

And if you're every nearby https://www.womrathbooks.com/ !

A sliced GCODE version of both bookmarks. I'm printing them in PETG at 1mm depth. We'll see how it goes :fingers crossed:
A photo of my printer starting it's print. Just some blue outlines for now.

New thread on my big ongoing embedded project since the other one was getting too big.

To recap, this is a pilot project for a bunch of my future open hardware T&M and networking projects, validating a common platform that a lot of the future stuff is going to run on.

The primary problem it's trying to address is that I have a lot of instrumentation with trigger in/out ports, sometimes at different voltage levels, and I don't always have the same instrument sourcing the trigger every time.

So rather than moving around cables all the time and adding splitters, attenuators, amplifiers, etc. to the trigger signals I decided to make a dedicated device using an old XC7K70T-2FBG484 I had lying around.

Of course, as with any project, there was feature creep.

I'm standardizing on +48V DC for powering all of my future projects as it's high enough to move a lot of power but low enough to be mostly safe to work around live. So I needed to design and validate an intermediate bus converter to bring the 48 down to something like 12 for the rest of the system to use.

The FPGA has four 10G transceiver pairs on it. I used one for 10GbE (not that I need the bandwidth, but I was low on RJ45 ports on this bench and had some free SFP drops) and the rest are hooked up to front panel SMA ports (awaiting cables to go from PCB to panel) to generate PRBSes for instrument deskew.

Since I'm pinning out the transceivers and am planning to build a BERT eventually, I added BERT functionality to the firmware as well (still need to finish a few things but it's mostly usable now).

And since I have transceivers and access to all of the scope triggers, it would be dumb not to build a CDR trigger mode as well. That's in progress.

@azonenberg so, jetlag basically. I hope you make it through without too much brainmush.

@azonenberg it's already date then time on the display, though? FWIW, I have come to land on a non-ISO YYYY-MM-DD[--hh-mm[-ss][--tz]] as it will always work with filesystems and globbing etc.

And now I'm at ObservabilityCon on the road, which is unfortunately keynoted by @RichiH-- Debian developer, insufferable German Deutschbag, my recurring HausGuest, and non-ironically one of my dearest friends.

@Quinnypig subtly incorrect. Yes, we can dynamically generate views and you can choose to persist them as dashboards. The first demo I showed was about "you have built a dashboard, so now let's generate good descriptions of what you built and what it does". Relatively well-constrained answer space with near trivial verification through the human -- and building shared language and thus understanding across the org and the wider industry.

@Quinnypig I will point out that I received actual spontaneous applause by following a mindset of "respectful and deliberate". Didn't expect that, but was pleasantly surprised.

The from Toronto to the airport not only has a diesel engine, it also has a gearbox and shifts gears. A train!

Not constant speed with generator and electric motors for higher efficiency, lower weight, lower cost, and less complexity.

Don't think I ever was in one of those -- or if I was, I certainly didn't hear and feel the engine.

Only one bed that's not mine and one extra time zone in my immediate future... Back home after three work weeks soon and really looking forward to it.

@azonenberg I've paid for, and not seen movement on since, two years ago so I'll take whatever I can get. The amount of time wasted standing in line for a quick "oh, you" while they scroll through my past itineraries is deeply frustrating.

RichiH,
@RichiH@chaos.social avatar

Yep, no customs. Exited directly into the normal gate area in SFO and could walk out.

Only two non-home time zones on my phone left.

RichiH,
@RichiH@chaos.social avatar

@azonenberg yes, I know.

My point was that preclearance is even better for me than for e.g. you as I have nothing, not even global entry because... They just took the money and are sitting on endless backlog.

RichiH,
@RichiH@chaos.social avatar

Interesting.. you can go through US customs in Toronto. I should land "domestic" in SFO and hopefully shave some time off of falling into bed at after midnight.

Boxers and socks to smell intensely like, for lack of a better description, old mushroom paste
