I've downloaded the newest master branch and loaded with a simple config generated by the web tool (I attached the config file). My Arduino IDE says it uses too much of program memory "Sketch uses 33024 bytes (102%) of program storage space. Maximum is 32256 bytes." I also tried compiling it with the -Os and -Oz flags to reduce the program size but with no luck.

I've been able to get it compile by turning off some options (DISABLE_PROBING_SUPPORT, DISABLE_COORD_SYS_SUPPORT, DISABLE_G10_SUPPORT, DISABLE_PATH_MODES) that were turned on be default. I think the web tool should automatically disable some of those options
