I just knew this great project in Jan 2026 when I just got my first 3D printer. And I also got a very old Raspberry PI 3B module which I bought ten years ago. Since the Open Flexure web page said Pi 3 is supported, so I just want to give it try.
I follow all the steps to download the latest image and burn it into the SD card. And plug in SD card to Pi 3. The only thing I can see is the black screen. No any response from Pi 3.
So I turned to AI for help. And with the only one action, AI successfully make the image work on Pi 3.
Here is the technical detail:
When you finish the image downloading to the SD card. You can find a “config.txt“ in the SD card (root path). Open it and update the content as following:
At the end of this “config.txt“ :
Original content:
[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
[all]
#dtoverlay=vc4-fkms-v3d
Change to
[all]
dtoverlay=vc4-fkms-v3d
It works! So if you’re using Pi3 and also struggling with the image, please try it.
