has been altered to send the X, Y, Z, and E coordinates first, followed by temperatures. It was the other way round. This led to compatibility problems between versions as the experimental multiple tool versions (duet branch V0.70+) report many temperatures and this was confusing the X Y Z stuff if the temps came first. We can only realistically have one live version of reprap.js (served from RepRapPro's Github to all running machines), so reprap.js now expects coordinates first, and both this master version and all future master and experimental versions will do that.

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:
