I'm a fan of touch screens, previously using the MKS TFT28 on a few 3D printers. There was some drawbacks, and understandably some people prefer the standard LCD display. Now the Bigtreetech TFT35 introduces new features and has the ability to switch back and forth between touchscreen and traditional LCD in seconds; it's the best of both worlds. These are a great match for any of the new BTT SKR boards, but are also compatible with ramps based boards such as the MKS Gen L.

This is a guide to installation and configuration, everything is timestamped below for your convenience. In case it wasn't clear, no firmware changes are required for the 3D printer.

Of the two TFT35s in this video, one I purchased as a customer and the other was provided free of charge by BTT. All opinions expressed are my own.

UPDATE Currently Octoprint + TFT35 works with the SKR mini E3 but NOT ALWAYS with the SKR V1.3. It seems the order in which they connect might be important, but I did manage to get both going at once.

Tip from viewer Dale for the SKR Mini E3 V2.0 connect easily to Octoprint when using a BTT TFT as well. Add this line to the "Additional Serial Ports" in settings: /dev/serial/byid/usbLeafLabs_Mapleif00
