I downloaded marlin 2.0.5.3 from their website
STM32F103RC_btt_512K is the environment
what do you mean by config header files
this is another picture of my issue and this is a fresh download of the firmware before I touched anything other than the config files i copied over from the example config files for “creality ender 3 with btt skr mini e3 v1.2”
