Hi!

A bit of background/motivation: Sharing photos of protests can be an important part of the PR of political organizations. However, not everyone feels safe sharing their faces in connection to political organizing. That's why usually, faces are pixellated, or people wear face covering masks (which might be illegal on protests in some juristictions). Pixellated/hidden faces are quite ugly to normies, though, which can reduce the effectiveness of the publication.

So I had this idea: What if instead of pixelating the faces, I run some CV software on the image and all the faces get swapped with the faces of Hedy Lamarr, Diego Luna, or JC Denton. I remember that Snapchat could do live faceswaps with the selfie cam ten years ago, so some desktop software like that shouldn't be too hard to find in 2025, right? /j

Unfortunately, all the stuff I managed to find was some computer science projects in which you train some monster model with one hell of a dataset of each face you want to replace/emplace (which defeats the purpose of anonymizing political activists). Or some obnoxious AI startup which is waaaaay too busy sucking off Elon Musk and/or Sam Altman. I don't want to give my money/data to some doomed AI startup which ends up selling our likenesses to the NSA.

TL;DR: Is there some kind of desktop software which detects faces in an image and swaps them with another face? It's ok if there's only a framework (as long as it's not as bad as all the horrible OpenCV results you find in online tutorials).

Edit: I found something that I can work with

I got a new Biqu H2V2 for my Ender 3 pro , since myold hotend started getting unreliable and that was a great excuse for yet another upgrade.

I wasn't happy with the carriage holder I printed, so I wanted to print a new one. After afew hours of printing, I needed to abandon one part, since it was incredibly messy with blobs of PLA gooped on the print. Since I needed the new carriage mount, I didn't think anything off it and simply abandoned that part and continued the other ones.

Today, I saw that the heating block is completely gooped up with PLA (see pictures). So now, I got two questions:

1. How should I remove that gunk? I was thinking o| carefully peeling of everything without the silicone sleeve while the hotend is at a low PLA-bending temp, like 150°C, or 175°C.
2. What caused this? Flowrate too high (the prints look the part)? Too fast extrusion? Heatcreep?

Thanks in advance. (:

Sooo müüüde =.=

Hi!

I've daydreamed about getting a cutter plotter without actually planning on really getting one. Too expensive and shelfspace-consuming for something that I'm not going to actually use that often.

Then I remembered that I could "just" mount a dragknife on my Ender-3 pro to do the job (maybe get one of these fancy quick-toolhead-changing systems as an excuse to tinker with CANbus, or something ;).

After a bit of online search, I found that I'm hardly not the first one with that idea. I've found a few videos, posts on reddit and files on thingiverse/printables, but nothing too in-depth. So I wanted to ask y'all if you know any resources to check out on this. Some github-pages style homepage of someone would be ideal, but I'm not too hopeful that there's something out there if I haven't found it yet.

Things I think I've found out:

• Roland Cutting Plotter Vinyl Cutters are apparently the way to go. With 45° for vinyl.
• I can use gcodetools to create gcode from svgs. The exact details aren't clear to me, though. Probably gonna have to create a klipper macro for this.
• I can simply attach a cutter to my toolhead, or use something like the BTT hermit crab for a more fancy approach

Things I'm still not sure how to do:

• If I'm using a BL-Touch - how should I handle z-homing? Can Klipper use BL-Touch for z-homing with an endstop-failsafe? Should I just monitor the print by hand?
• Is there a comprehensive guide on the materials?

Do you have any experience on that topic?

The Rule of Law

Hi! I'm sometimes handling photos of people who wouldn't like their real faces shown. But pixellation isn't a very PR-friendly practice if you want to publish the images (e.g. photos of a protest).

So I remembered that ages ago, back when I used snapchat that they had this simple faceswap feature that was able to run on a simple smartphone and I was wondering:

Is there a simple, easy to set up program that takes the faces of a picture and faceswaps them with another, available face?

I was thinking of getting a random face from this-person-does-not-exist.com and superimpose it on the faces of the photo. This way, it's protecting the identity of the people on the photos, while keeping the photo easy to look at (plus, no one else's likeness will be used unconsentually).

After a quick google, I found faceswap.dev, but then I read stuff about extracting, training and converting and deemed it overkill. The feature I was thinking of was done for two people swapping their faces on a live video feed on a phone. I don't want to go broke by throwing a GTX 5090 on that problem.

Do you know any problem on Desktop (or maybe on android, or a selfhosted service) that can do that kind of thing? IMHO, it shouldn't be too hard.
