Configuration and firmware options in front end - do they actually work ?
edited December 2016
As per my title - documentation mentions uploading a printer configuration. if it means the configuration.h from the FW - then this doesn't work as the upload button stays greyed out......
That is not the configuration we are talking about here. We mean the server configuration for your printer so you can copy it to a different server installation and have the identical settings from the start.
How should the server know what to do with a configuration.h file? That is only a small part of firmware sources and need to be compiled. What is possible is to use the firmware uploader form server to upload a compiled firmware as described in documentation. But here also you need to compile yourself first and then upload the new binary you just compiled.
