My Klipper series continues with a video exploring three and a half options for adding an interface to the 3D printer. In this step by step guide, we cover headless, reusing a mobile phone or tablet, an LCD with click knob and a touch TFT with KlipperScreen.

Each has strengths and weaknesses, so hopefully with this information you can make a decision which best suits your hardware and skillset. If you have another option I haven’t covered here, please post it in the comments.

Thank you to Gadgetoid for leaving the solution in this issue on GitHub:

Add a ‘#’ before dtoverlay=vc4-fkms-v3d in /boot/config.txt
Then follow the “Persisting Rotation“ section as the base of https://github.com/pimoroni/hyperpixel4
