Added new request code rr_data for file uploading, and made other changes to improve file upload speed. Implemented S parameter to M208 command, to allow the negative limits of axes to be set. Also reports current limits of no X/Y/Z parameter. Reduced max reported free buffer size to 950 bytes to avoid problems with file upload from Windows 8.1.

RepRapFirmware - Webserver
|
|
|
|
This class serves a single-page web applications to the attached network. This page forms the user's
|
|
interface with the RepRap machine. This software interprests returned values from the page and uses it
|
|
to Generate G Codes, which it sends to the RepRap. It also collects values from the RepRap like
|
|
temperature and uses those to construct the web page.
|
|
|
|
The page itself - reprap.htm - uses Knockout.js and Jquery.js. See:
