Basic Information:

Printer Model: Ender 3 Pro
MCU / Printerboard: BTT SKR Mini E3 V3.01
Host / SBC Raspberry Pi 4 / Pi Cam Module 3
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

I’ll admit this may not be the best place for assistance so if there’s a better place, lmk.

I had this camera working with Marlin & OctoPrint. I’ve since switched to Klipper and I’m stumped.

The system is detecting the camera:

vcgencmd get_camera

supported=1 detected=0, libcamera interfaces=1

libcamera-hello --list-cameras

Available cameras

0 : imx708 [4608x2592] (/base/soc/i2c0mux/i2c@1/imx708@1a)

I’m happy to provide more logs, configs or CLI output.

Thanks in advance for the assist! This community is outstanding, thanks all!

Welcome pspblink,
since nobody is replying, I’ll try.

I don’t use a camera.

My advice would be, try another forum (but I can’t guide you). My impression is, cameras are a little taboo here. They use a lot of capacity of the system, so they are not recommended. Have a look at the Magneto X with genuine Klipper Magneto X Magnetic FFF 3D Printer by Peopoly, which comes with a HD camera (does not help you, but it’s working).
I’m also thinking about installing a camera. I would reduce the frame rate and resolution to keep data traffic from the camera low.
What is your goal? Do you want to check your current print or do you want to post fancy videos of your print?
A big chunk of data from the camera might cause Klipper problems. I hope this helps you.

Great insight. Thank you. I figured I’d need to adjust the resolution and frame rate once operable.
Mostly for error detection via Obico and remote print monitoring.
Maybe timelapses, someday, maybe.
