@ellensp regarding format-pins there is a problem with the makefile in windows anyway, as line 29 has double quotes that the SO doesn't like and will not run as it is PINS_RAW := $(shell cmd //c "dir /s /b Marlin\src\pins\*.h 2>nul | findstr /r ".*Marlin\\\\src\\\\pins\\\\.*\\\\pins_.*\.h"") I think solving it will just open another issue in other line

line 29 $(error No Python executable found – install Python 3.x and make sure it is in your PATH)
It has no quotes what so ever.

Sorry, just to clarify, ignore the line/quotes I said, the output of the command is:

PS D:\Git\Marlin> make format-pins       
El sistema no puede encontrar la ruta especificada.
Makefile:29: *** recipe commences before first target.  Stop.

Although I agree its poorly formatted. It works on my test windows 11 machine without errors...

After fighting with windows for several hours I've given up on using windows cmd line tools and used python to bypass all of the window weirdness with finding the required files

Since I cannot replicate your make error, please test https://github.com/ellensp/Marlin/tree/update-makefile
You can see the files changed here bugfix-2.1.x...ellensp:Marlin:update-makefile

If it also works for you, ill make the pr non draft.
