Hello,

I am trying to compile the firmware on the custom firmware builder but it keeps erroring out. I have the TFT 35 display with my BTT SKR Mini E3 board on my CR10 V1 printer with a BLTouch and a Micro Swiss Direct Drive Extruder. They were working great until it somehow lost its firmware. Now this site will not compile it for me after I paid to make it easier on myself then last time. Any suggestions?
