Unfortunately, it's been over a year since the Russian team has answered any request for support. I'm planning to post the situation to the Inkscape developers mailing list (because of an issue with a different user) and ask if there is any other place we can go for support. I'll post whatever replies I get.
I've recently learned a very little bit about using some of those gcode tools, trying to help Inkscape users. But since I don't have a woodshop (much less CNC), I can only use a simulator to find out if the code works!
I don't know what you mean by "OX" or "Rino", if those words are supposed to explain your project. So if you can be more specific about one particular project, there's a slight chance I could give you more specific suggestions. But for now, here's what I know. No matter what you're doing, you have to do the following 2 steps first.
- Extensions menu > Gcodetools > Orientation Points -- I haven't learned what the 4 options at the top mean. So far I've only used 2 points mode. But the last option allows you to set what kind of units you want to use. This will put 2 points on your canvas (and I assume creates certain parts of the gcode, once it's output).
- Extensions menu > Gcodetools > Tools Library -- There you need to choose what kind of cutter you want to use. This will put a green box on your canvas, showing several variables. You can change those variables using Inkscape's Text tool. (Surprisingly to me) the gcode which is output uses those variables, even if you manually change them.
- Which extension you use after that, from what I've learned, depends on your project. Like if you're going to be engraving, choose Engrave (from the same submenu as above). Or if you'll be removing an area of wood, choose Area. Or etc.
- As far as I've learned, if you're simply cutting something out - let's say for simplicity, you want to cut completely out, a round disc (circular path), go straight for Path to Gcode extension (after steps 1 and 2). Most of those options are more or less either explained, or self-explanatory. There are several that are still a mystery to me.
- After you click Apply on whichever extension you used as your 3rd step, the NGC file will be created and placed in whatever directory you indicated on the Preferences tab (of Path to Gcode dialog, or whichever extension you used). And also a log file, if you opted for one (same Preferences tab) Also, it will add certain graphics on the canvas, colored line segments and arrows. I'm pretty sure the arrows are indicating the direction of the path, which I also assume is the direction the cutter will take. But I haven't figured out what significance the colored segments have.
Another thing I've learned, is that Inkscape's gcode tools can't create gcode for every possible type of CNC project. I've run into a couple of people who eventually determined that Inkscape's tools can't do what they want. So it very much depends on your particular project, not just which extension you use, but whether Inkscape is the best choice at all.
