Trying to create a printer.cfg. Is it possible to get fan pin and stepper current info from marlin source?

Sineos · January 27, 2023, 7:13am

Following is the logic and the way how to find such information in Marlin sources:

Identify the MOTHERBOARD in the relevant Configuration.h
Find it in boards.h
Then scroll up in boards.h to see which is the leading MCU type
Find the pins_XXX.h in the relevant folder of the MCU type
