Learned today that my #prusa Mk3s should get a little maintenance every couple hundred hours of print time. Thought I'd check.
Oops. 1200 hours. Better schedule some maintenance before it schedules it for me.

Looks like they have finally released a fix for the MMU3 overcurrent issue that a number of people have been experiencing on their #Prusa MK4 printers. If you are one of those people here is a link to the beta firmware.

Its taken way to long to get this but at least its here.

I just tried the #prusa app for #android and for any #blind #3dprinting folks out there, it works just as well as the iPhone and iPad version does. You are able to access the printables section well enough and the headings are clearly labeled and such. It is surprising what you can do with an app for your prints. You don't even need your computer anymore it seems. Whatever they did, they focused some of their resources on accessibility which is very refreshing and convenient for any blind folks who may want to start printing. A very good showing from Prusa and their quality software. It makes me want to consider a prusa printer all the more as the software is half the battle.
I love listening to the soft crackles of a PETG print detaching itself from the Satin PEI sheet on my printer. Great adhesion while it is printing, not attached at all after cooling down. Great engineering!
Hey #3dprinting #prusa folks, does anyone have any idea what's going on with this benchy? This is my first attempt at printing with ASA (polymaker polylite) on a mk4s. I've tried the standard prusament ASA profile (which others online have had success with) as well as the generic ABS profile and both show this really strange distinctive diagonal hatching
Pop quiz: There's a costume party in 2 hours, and all you have is a pair of cat ears and a 3D printer. What do you do?
We were invited to a birthday party over the weekend, and the hostess wanted everyone to come in "party animal" costumes, even if you "just throw on those old black cat ears you got for Halloween".
@llorenzin and I would be masking, since the party would be a bunch people in a small apartment, and I got to thinking about what I could do to add to those "old black cat ears" from the Halloween box...
One of my protective masks has a SIP valve for drinking using a small straw. While out running on Friday, I thought about how could replace the SIP cover with one of my own design, adding an arch that could be used to hold some pipe cleaners as whiskers.
We ended up with a very busy Saturday, but with a couple hours to go before the party, I pulled out my calipers, pulled up Tinkercad, and threw together a simple design for a cover with an arch (made of just 3 basic geometric shapes plus cutouts).
My first two prints failed because I didn't slice it with supports under the arch, and the "arch" ended up as a big ugly glob of plastic. Doh! After re-slicing with supports, it printed great. The fit over the SIP valve was good, and it worked just the way I had hoped! Yay!

Ended a week of evenings of me and mrs. T working on PrintDOG. It started as a Prusa i3 Mk3, studied hard and became an S, more studying and it was a + for a while.
It was working well but a few parts were wearing out. I was considering replacing it with a Bambu P1S Core-type printer - then Bambu went and did their 'thing' that made me really appreciate the open nature of the Prusa platforms.
And since I'd originally built PrintDOG as a kit, I was kinda familiar with what went where -- I ordered an updgrade kit and now PrintDog is a Prusa MK4S.
And working amazingly well.
I'm also rebuilding some vintage bookshelf speakers. The paper gaskets were not recoverable so I modelled and printed replacements.
Good PrintDOG!
Oh, shoutout to @MaryPot for the heads-up on the Bambu thing... it's kinda scary.

@3dprinting Printer builds/upgrades are among the few times when I swing my second monitor over to the workbench.
Admin note: I am dropping the #3DPrinting and #Prusa hashtags from the rest of the thread. Follow #MK4SUpgrade (or me) if you want to see the rest.

New build thread.
I am upgrading my Prusa MK3 to MK4S. I ordered the kit on Black Friday, and I've been getting other projects off my plate so I can start on it.
Tagging @jasoncoon and @younata because you both have experience in this.

Spend the weekend upgrading my Prusa Mk3S+ to a Mk3.5S. While I was at it, I also swapped out all the accent pieces for my favorite color.
As is tradition, my first print was a Benchy.
Love this stupid machine. #3dprinting #prusa #mk4s #mmu3

The MMU works well with #Octoprint. I use Octoprint mainly because it offers me more options than the Native Prusa solution. You select the material in the slicer - which should of course be loaded in the MMU - and then send the print file to Octoprint. Octoprint will ask you if you want to print with the submitted filaments or something else, or if everything is ok, and then start the print.
Of course, this requires flawless interaction between the MK4(S) and MMU3 at the hardware level. I had some initial problems with this, but they had nothing to do with Octroprint.
In the meantime, I have made some extensions [(un)original heatbox, different buffer system, housing and a few other small things] so that I could start production.

Vaguely apple-like 3d printer company that makes very nice, very performant, and relatively affordable 3d printers with lots of whiz-bang features.
They allegedly stole a lot of stuff from #Prusa (basically their entire printables.com website is what I heard), and they're now walking down the darkened path of #enshittification, although I don't know the details, tbh.

If your needs are met by the #Prusa mini, buy that.
I started with the MK4S, and now have the full range, from the mini to the XL and have been happy with all.
If you are not comfortable with complex assembly, get a preassembled model, but remember, some tuning of mechanical parts is unavoidable over time, and that may involve partial disassembly and reassembly, for example maintenance of extruders.
One hard-learned lesson was to NEVER let filament unspool and become loose!

I'm thinking about buying a 3D printer; specifically the Prusa MK4S. I don't really *need* it, but it would be nice to print my own D&D miniatures, and in the past I've occasionally wanted to print other small objects based on designs I found online.
Any thoughts about 3D printers in general, and about Prusa in particular?
As the #BambuLab users are slowly waking up to what https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/ means, it's a good time to remind everyone that the writing has been on the wall from day one.
It's not a "told you so", mind. It's a "this will continue and get worse". #Bambu will continue to tighten the ratchet.
#Prusa is far from perfect, but they deliver reliable #3dprinting based on open source software at an acceptable cost.
And if you missed it: they allow you to maintain warranty with custom firmware again.
