Camera compatibility (RPi + PrusaLink)

Tento článek je také dostupný v následujících jazycích: 

PrusaLink for Original Prusa MK2.5/S or MK3/S/+ printers is powered by an Raspberry Pi (RPi) board. A camera can be connected to it either using CSI or USB connection.

Alternatively, the same camera setup is also compatible with RPi + Octoprint on MK4 / MK3.9 / XL printers. Note that PrusaLink itself running on MK3.9, MK4 and XL printers doesn’t support any cameras. You can use Prusa Connect, where it is possible to assign a camera to any of the supported Original Prusa printers.

Compatible RPi cameras connected via CSI (MIPI):

All the official RPi cameras in the list below have been tested and are compatible. PrusaLink uses a "whitelist" for CSI cameras. For example, if you connect RPi camera 3, it identifies to the RPi as "imx708" (according to the actual camera sensor it uses). The Wide-angle variant of the same camera identifies as  "imx708_wide". If you use a camera that would identify differently than any of the whitelisted ones, it won’t show up in PrusaLink.

There are also other compatible cameras than the ones listed below, such as some Arducam models. However, we haven’t tested them and can’t guarantee they will work as expected or will not cause any issues.

If your CSI camera doesn’t seem to work - and you are an experienced user, you can connect to PrusaLink using SSH, or connect a keyboard + monitor to the RPi and use the following command to find out if the camera is detected and what it identifies as:

libcamera-hello --list-cameras 

Note that due to limited computing capabilities of the Raspberry Pi Zero, the resolution might be limited to 1920px in both axes on this RPi model.

Compatible USB cameras:

The RPi board also allows you to use a USB webcam. 
Following USB cameras were tested. There are also other compatible cameras than the ones listed below. However, we haven’t tested them and can’t guarantee they will work as expected.
