Initial implementation of babysteppnig Fixed some issues with file upload and FTP networking on Duet Ethernet (but FTP notr working yet) Pass the name of the firmware file to IAP Duet Ethernet and Duet 085 now each have their own Webserver modules

RepRapFirmware - Configuration
|
|
|
|
This is where all machine-independent configuration and other definitions are set up. Nothing that
|
|
depends on any particular RepRap, RepRap component, or RepRap controller should go in here. Define
|
|
machine-dependent things in Platform.h
