Loading GCODE file from URL

[hackwin]

Any ideas on how to load the GCODE from a URL?

Sorry, modern browser security prevents cross site requests, so there is no way to implement loading from url without server side. I have no plans on making that viewer server dependent.

Thanks for replying. I needed to load the file from within the same domain. AJAX worked fine

Could you share your code snippet how to load gcode from an URL? Many thanks in advance!

Lines 187 to 209 contain the added code: http://ideone.com/5oTp9e

You can run it from the browser javascript console using: GCODE.gCodeReader.loadUrl("http://localhost/gCodeViewer/model.gcode");

Thanks a lot! Unfortunately it's not working. Are you still using it? And on what commit of gCodeViewer?

I will give some extra info below in case you wouldn't mind reading it and have a quick solution, but with no means I expect you to invest time in it and fix my issues of course.

The latest commit gives me a "gcode.match is not function" error in detectSlicer and a js syntax error on the gcode file itself (as if the browser tries to interpret it as a javascript?). After adding "gcodeResponse = String(gcodeResponse);" to the loadUrl function the gcode.match error is replaced by other errors like: "TypeError: Argument 1 of SVGMatrix.translate is not a finite floating-point value" I switched to the commit which is close to your original post (Oct 8 2013 so I took: a797c52a3b35ead10d8dba8e2fd9da5bbf328b35) but that didn't fix it either.

Here's a copy of the code I used: http://jbcse.com/downloads/gCodeViewer.zip

Here's a demo page: http://jbcse.com/projects/gCodeViewer-from-URL/

Enter into the console: GCODE.gCodeReader.loadUrl("thin-wall.gcode");

Thanks mate, stupid of me I didn't check Chrome, works like a charm there, but not in FF, so it was a browser issue. Thanks for your help, I will use it in chrome until I gain super javascript powers.
