(what comes to mind is helping a friend of mine fix their car door, which had acquired a big dent at the front of the door, so that the door couldn't open very far and I was in my 20s at this time I thought heck, we just need to bend it in further but the more we bent it the worse it got and in the end, the solution was just the opposite - it had to be pulled out!) (because both pieces share the same arc, and the door can only open if they share the same arc) Anyway, just a thought Too often I've made quick decisions like that, and regretted it in the end (not always using Inkscape, but in general). Not that I have much experience in this scenario, but I wouldn't be too quick to delete the arcs and draw rectangles.unless you know the theory behind requiring arcs, and you know that it's irrelevant in your case. Because the 2nd time will distort it severely! And I have no idea whether you have room for any slight distortion, or whether you need strict precision. But it will also slightly distort the path. You could try doing Path menu > Simplify, which will reduce the number of nodes significantly. Since we can't see the file, I don't have any idea whether you actually need that many nodes. But I'm glad you found the backup files! I'm rather shocked that Inkscape backed up the products of the extension.but good that it does!

I suppose there would be some way to identify the source of the crash, but I'm not so technically inclined as to know how to find out. 2000 nodes would cause some performance issues for me on my machine. Since you're using that extension, it might be something having to do with that. The crashing may not relate to Inkscape in this case. But wherever I read that, it probably applies to those home craft cutter machines. I don't know about your particular setup, but somewhere I think I read something about additional nodes making the cutting easier. Oh no, it's not the number of nodes per object, but the number of nodes per file, regardless of how many objects. Of course, that means I've got to re-draw the pcb. These are always designed as circles, but I can no reason not to make them rectangles, and thus speeding up the whole cutting process. Looking at the code, I can see that the vast majority of the time is spent cutting small arcs to generate the 'pads' that components are soldered to. It will be nice to eventualy find a way to stop it crashing/freezing, but in the meantime my pcb project can move on. Sure enough it crashed, but in the wreckage was the precious. So back to my original file of some 2000+ nodes, and set to work. Lo and behold, there was the gcode, complete. ngc file, so I opened that in a text editor. svg file with a date/time stamp as part of the file name, I opened it, and there was the final screen I'd seen as it crashed. I ran this throught the gcode tools, but it crashed again However, I rather got carried away and left only one object with 172 nodes on it !

I broke my path into 200 objects and decided to delete some of them to give the programme a fighting chance.

I then tried repeating the process with my large pcb pattern file, but it keeps throwing up 'internal error' windows and closing.Д«efore it does so, the window with the original pattern appears with what looks like the conversion to a series of arrowed lines around the path, so it is working to some degree.ДЄfter all that, I suppose my first question is, is there a limit to the number of nodes in a path that this extension to Inkscape can cope with ?

Having sorted out the above, I set it in motion, and was delighted to find a.

Then, as various other hitches occurred - 'path is in root', so you must add another layer, I decided to start with a simple rectangle.

I have now run into a variety of hitches/problems, the first being that it took a long time to discover that I had to rename the directory the code would be sent to, namely /home/john, not just /home. I've edited this, straightening up a lot of lines, removed a lot of nodes and finished with 2122 nodes on a 'single path'. png file, and re-imported it, scanned it and obtained an outline path with about 2500 nodes. I then exported this as a bitmap in 2 colours, saved as a.

My current project is to engrave a pcb, and having imported an illustration from a pdf file via a screen grab, I used inkscape first to redraw the layout with a 1mm 'pen'. 0.48 on a laptop running ubuntu 12.04 as a means to supply gcode to my cnc wood router running Linuxcnc.
