Please be detailed and give a clear description of your issue. The reporting template is there for a reason, not to just delete everything.

Anyway, the error message comes from Marlin, not from the TFT, so I suspect your Marlin configuration is not correct.

Seeing the exact same thing after updating my firmware after a 3 year hiatus for my Ender 3 with TFT35 3.0.

Console is spammed with M710 missing just like shown here: https://www.reddit.com/r/Artillery3D/comments/1g1iuao/unknown_command_m710_and_mainboard_fan_not/

(fyi switching the fan from 255 to a lower value did not work for me to fixing it)

Mine is a TFT35 3.0 though running latest Marlin 2.2 bugfix. I tried with and without
#define CONTROLLER_FAN_EDITABLE // Enable M710 configurable settings
and still get it spamming the console.

I have all of the recommended features enabled in Marlin (except SDSUPPORT because it won't fit on my firmware)

What can I provide to debug this?

I ended up fixing this by restoring default settings in my TFT35 menu. Wow, what a weird bug. Perhaps some old leftover code stuck in memory? No more console spam. Hope this helps others find their sanity (I re-compiled Marlin over 10 times).
