Prusa has a Political problem on Printables

Eds_3D_Odyssey — Thu, 11 Jun 2026 20:40:32 +0000

I was on Printables the other day and I was looking at the Pro and Anti Trump models. All I can say is I hope the people leaving comments on those models never find this forum!!! I’m very surprised and disappointed that Prusa let’s people talk like that to each other. I did report some of the really nasty stuff so it will be interesting to see if Prusa takes any of it down.

A Learning Moment

Eds_3D_Odyssey — Thu, 11 Jun 2026 15:26:26 +0000

We all have are moments of stupid, some of us have more then others.

A few days ago I was trying to be funny and I insulted someone and probably hurt their feelings. I did apologize. I also thought about asking the Mods to take down the Post but after thinking about it for a while, maybe it’s best to keep it up. It’s a good reminder that just because you think something is funny doesn’t mean other people will and what you’re trying to say and what other people hear are not always the same.

What if you knew every printer, laser, and skill two streets away?

Hi everyone,

Long-time lurker, first real post. I'm an engineer, designer and maker (3D printing, electronics, a bit of robotics) and I've been chewing on something I wanted to put in front of people who actually get it.

The maker capacity in any city is huge but scattered: someone has a printer at home, a fablab has a laser, a neighbor runs a CNC in their garage, and above all, there's a ton of skill spread around. The weird part is we almost never know who has what two streets away. We end up ordering online something a neighbor could've helped us make in an afternoon.

So I built fem. (Catalan for "we make"): an open map of a city's maker fabric, where anyone can put their machines and skills on the map, find other makers nearby, and team up. It's part of my master's thesis at Fab Lab Barcelona (IAAC), so it's really an experiment about activating what already exists in a neighborhood, not a product. It's free, it's not a marketplace, and there's nothing to sell.

It's seeded in Barcelona right now, but the idea isn't Barcelona-specific, which is exactly why I wanted to ask here:

Would you use something like this where you live? Is anyone already doing it well in your city? What would actually make you put your printer and skills on a map, and what would stop you?

Link if you want to poke around: fem-barcelona.lovable.app

Honestly, what I need most is makers tearing it apart and telling me what's broken.

Thanks!

Mini-Poll : Would you map your gear and skills on an open maker map in your city?
A : Yes, I'd add mine today
B : Interested, I'd watch how it grows first
C : Only if there's a real critical mass of makers near me
D : Not for me, and I'll tell you why

Why does it seem Prusa is not very active on this forum?

Is my impression right, and does Prusa seem to prefer Reddit and Discord for communication?
And if so, why is that?

Problem saving custom filament profile in PrusaSlicer – crash and configuration reset

Adam Kábrt — Wed, 10 Jun 2026 08:39:08 +0000

Hi everyone, I would like to ask if anyone has experienced a similar issue, or if the Prusa team could possibly look into this.

I am working on my bachelor’s thesis, where I am testing and tuning the material BASF EL60 RESIN. After gradually adjusting the settings, I created my own material profile in PrusaSlicer.

The problem happens when I try to save this material profile as a custom filament, so I do not have to enter all the values manually again.

After saving the custom material, PrusaSlicer closes/crashes. When I start it again, it opens in what looks like a backup or recovery mode, where almost everything is enabled. However, my custom material settings are missing.

The only way I have found to fix PrusaSlicer is to go to:

%appdata%

and manually delete my newly added custom material from the configuration/library folder. After that, PrusaSlicer starts normally again.

I would like to ask:

Has anyone experienced this issue before?
Is there a correct or safer way to save a custom material profile?
Could the Prusa team check whether this might be a bug in PrusaSlicer when saving custom material profiles?

I am using PrusaSlicer for material tuning as part of my bachelor’s thesis, so being able to save and reuse settings would help me a lot.

Thank you for any advice or help.

A little thanks to the helpers

Just wanted to toss out a quick thanks to the people helping around the forum.

There are a lot of questions that come through here. Some are easy. Some are weird. Some start with “my printer is possessed and I need an exorcist".

Which... fair. We have all had those days. Honestly, I do not miss looking at 101 photos of first layers before full auto bed leveling.

But when people jump in, ask a few good questions, point someone to the right article, share a setting, or just help calm things down a bit, that makes a difference and really makes this community a helpful place for one another.

That is the normal forum activity I would like to see more of.

If someone helped you, toss them a thanks.
If you figured something out, please come back and post what fixed it.
If you see a new user stuck, help them get started.
If you have a project going, post it. Weird projects are allowed. Sometimes preferred. (anime, mech, comic book, cosplay, themed set ups would certainly NOT be the preferred posts ((joke)) ) 🙂

This place works better when it is not just problems, but fixes, ideas, prints, and people helping people.

So, thanks to everyone jumping in and helping where they can. It really does matter and makes this a better place.

Brief update on the forums

Same Old Shane — Tue, 09 Jun 2026 19:15:25 +0000

Hello all.

To try and keep users updated here, as mentioned before there has been work towards updating the forums on the back end of things and I figured to give you an update.

The work continues on it as far as working with different internal teams, seeing what can work and what can not, what stays and what might need to be retired. One thing to keep in mind that this forum is fairly on the large size when you consider the forums offer 6 different languages and sections in the forums going all the way back to the MK1 series of printers and a few other topics.

We have had multiple meetings and sit downs as far as what can be done, what to use, and submitted various feedback that the community has provided previously.

I dont want to say which software will be used just in case I say we are going to use platform A, and then something might arise and we have to change it to a different platform and then just confuse myself along with the community :)

This is a high priority internally, and while I hate giving this answer as it would drive myself crazy, as far as when the changes go into effect, the only answer is "soon". Why? Because there are multiple things that have to fall into place and play nice with one another. The forum will play a major part in that for the backbone of a few different related projects, so it has to be done in a way to make sure everything works together well enough.

I know there is little new info here, but I wanted to write and let the users know that the forum update program is still active, still being worked on and has not been forgotten :)

DO NOT BUY FOR FIRST TIME PRINTERS

wburn — Sun, 07 Jun 2026 18:48:54 +0000

I bought a Core One plus. Within a few weeks I have a clog that I am unable to clear.

I have tried both the instructions for cold pull on the printer and on the website.

I now have a $1,500 paper weight as the gears click trying to load filament.

To make the point, it was Prusa filament as well...

I can not find a help section to contact support, so this is it. Unless you are professional 3d printer, I would strongly suggest looking elsewhere.

Firmware Update

Nodak7 — Sat, 06 Jun 2026 14:32:21 +0000

Help! I updated the Firmware on my MK4S (with MMU3) to "Firmware 6.5.3 (3.0.4) MK4S, MK4, MK3.9S, MK3.9". After I did that I get an error on my printer that the MMU is not compatible with this firmware. I looked at the website under the MMU and the update is the same name and size. What am I doing wrong? Should I just revert back to the old Firmware?
