Behavior:

✅ Rotation works on the still preview image

✅ Rotation works on the RTSP stream

✅ Rotation works in the Prusa Android app (preview + live)

❌ Rotation is not applied to the WebRTC stream when hitting Play on connect.prusa3d.com or in PrusaSlicer

Looks like the rotation transform is missing specifically from the WebRTC pipeline — RTSP and the Android app apply it correctly.

Setup:

Camera: Buddy3D (standalone "snowman", not the Core One version)

Camera firmware: 3.1.4 PrusaSlicer: 2.9.4

Tested in Chrome and Firefox on Linux Prusa

Android app: rotation works correctly

I am wondering whether I could use the "Buddy3D Camera for Prusa CORE One" also within my custom built enclose with MK2.5S. I really like the small design factor of the Core One Version in comparison with the normal Buddy3D Camera.

In the manual it says "There are two versions of the Buddy3D camera. While both are compatible with all the current Prusa printers, only the latter is designed for the internal installation in the CORE One." In the shop it says not compatible with MK2.5S, which confused me a bit. 

I will figure out how to mount the "Buddy3D Camera for Prusa CORE One" in my enclosure on my own. Is there any software limitation (e.g. communication between camera and Core One), that my MK2.5S cannot not cover? Does Prusa Connect fully support this camera even if not used with Core One?

I've been getting some good use out of the buddy3d camera in my core one+, but I have been having constant issues with the camera overexposing the image.

I have tried dimming the lights in the Core One down to as low as 20%, and also turning off the lights in the room the printer is in, but the auto exposure algorithm in the camera always overexposes the image.  It works for seeing if there are any gross printing errors but all detail is lost on parts of the prints. I was planning on using the buddy3D camera to make time-lapses of my print jobs, but this overexposure issue completely ruins that.

Is there any way to adjust the exposure levels of the camera?

i'm running Core One with USB camera locally without internet connection (is on wifi). Same applies to the printer. Is there any way to manage the camera without Prusa Connect app? Local RTSP stream works fine.

For example pull snapshots from the camera via wifi, setting the resolution, and so on. Is there any public REST API available for the camera?

thanks

this is for advanced users - you can run rclone on the camera, but it needs some scripting (memory limitations require killing camera app, so that rclone can be used)

https://github.com/nvtkaszpir/3d-print/tree/main/prusa-buddy3d-camera - this may be updated over time, so please check it out before asking.

you can ask me on Discord for more, or ask in this thread.

Tape the phone screen with a transparent matt surface tape at least for the qr code part. Overlap the tape a bit and make sure there are no significant marks or air bubbles. When the camera announces that it is scanning for qr code, bring the phone slowly from 25 cm to 10 cm towards it and it should scan the code in 10-15 cm distance.

The issue for me was with the phone screen reflections. Hope this will help someone else!

If the connection fails, there are other topics related to that how to fix those issues: Don't use special ingredients in the password or network name like #/!- or such, use the 2.4 Ghz network and double check the name for the network and password.

Prusa Connect iOS: v1.13.13+297

Buddy Camera pairs successfully and works normally in Prusa Connect Web (desktop) — live feed and timelapse both visible and stable.

However, the camera never appears in the Prusa Connect iOS app. The app continues to show “No camera added / Add camera” even though the camera is already paired and active. This happens even when the QR pairing is initiated from the iOS app.

Tried:

Verified same Prusa account on web + mobile

App logout/login, force close, reinstall

iPhone restart

Printer & camera power cycles

Latest printer firmware

Camera + printer on same network

Removed and re-added camera

iOS Local Network permission toggled

Web UI consistently shows the correct state; issue appears iOS app–specific (likely caching or XL camera sync). Is this a known issue, and is there an ETA or workaround?

Prusa chat wasn't able to help me. Appreciate any ideas on what to try next.

The camera has the current software. Is this a problem with my particular camera or does this feature just not work at the moment?

Cheers, Bryce.
