  9. # Firmware is Smoothieware.
  10. # Provided config-file is for the cohesion3d remix and to use in the 3D-printer ‚weCUBE’.
  11. # More information at www.well-engineered.net
  12.  
  13. # there are advanced options to configure a pin:
  14. #   !   invert pin
  15. #   o   set pin to open drain
  16. #   ^   set pin to pull up
  17. #   v   set pin to pull down
  18. #   -   to set no pullup
  19. #   @   to set repeater mode
