Getting Data from G Code

[nraynaud]

Thank you. I have troubles understanding your question, could re-formulate it or give me some context please? There is a "Gcode" button in the top left corner of the app, does that answer your question ?

Hi Raynaud, thanks for the quick reply.

I am looking for a G code data simulator to map G code and actual machine raw data. I see that your app is internally converting it G-Code into the tool path, but how do I get the data out of it? Can I get the data into something like the X, Y, Z coordinates and the Speeds/Feeds/Tool information etc?

[nraynaud]

well, I have not developed that. What kind of file format do you envision?

Please take a look at this.
https://www.npmjs.com/package/gcode-toolpath.

[ { motion: 'G0', v1: { x: 0, y: 0, z: 0 }, v2: { x: 0, y: 0, z: 6.35 } }, { motion: 'G0', v1: { x: 0, y: 0, z: 6.35 }, v2: { x: -12.7, y: 0, z: 0 } }, { motion: 'G0', v1: { x: -12.7, y: 0, z: 0 }, v2: { x: 0, y: 0, z: 2.54 } }, { motion: 'G1', v1: { x: 0, y: 0, z: 2.54 }, v2: { x: 0, y: 0, z: 0 } }, { motion: 'G2', v1: { x: 0, y: 0, z: 0 }, v2: { x: 0, y: 12.7, z: 0 }, v0: { x: 12.7, y: 0, z: 0 } }, { motion: 'G2', v1: { x: 0, y: 12.7, z: 0 }, v2: { x: 12.7, y: 0, z: 0 }, v0: { x: 0, y: 0, z: 0 } }, { motion: 'G2', v1: { x: 12.7, y: 0, z: 0 }, v2: { x: 0, y: -12.7, z: 0 }, v0: { x: 0, y: 0, z: 0 } }, { motion: 'G2', v1: { x: 0, y: -12.7, z: 0 }, v2: { x: -12.7, y: 0, z: 0 }, v0: { x: 0, y: 0, z: 0 } }, { motion: 'G1', v1: { x: -12.7, y: 0, z: 0 }, v2: { x: 0, y: 0, z: 2.54 } }, { motion: 'G0', v1: { x: 0, y: 0, z: 2.54 }, v2: { x: 0, y: 0, z: 6.35 } } ]

But this is fairly basic, unlike your app which can handle complex paths. And it internally has all the information required already. I was wondering if there was an easy way to expose it. Or would you would know another project that does this?

[nraynaud]

ok, you want the parsed G-code ?
you can call evaluate() in here: https://github.com/nraynaud/webgcode/blob/gh-pages/webapp/cnc/gcode/parser.js

'text' is the g-code text.

Thanks. I think that might answer the question, but I need to understand basics of javascript to figure out how to run that. I will get back to you once that is figured out!
