I had a good hour of trying and error until I figured out how to do.
I had tried longtime ago, without any success, but I thought why the hell not ? Lets give it an other shot. Recently I stumbled over a post about generating gcode straight from Inkscape. At that point I did really pushed the LEAD 1515 speed even more. Most of my gcode files were halve after that. This was a game changer, since the script from AcrwelderLib trades many lines of G1 code to 1 single line of G2 or G3. Until one day, I discovered the AcrwelderLib library on Github. I had been quite happy with those scripts. It Makes the work quicker more efficient and so on. I ended using the well known travelling salesman problem algorithm to limit unnecessary travel of the head. I think Opencam queue the cuts from the smallest to the biggest. The second script I wrote was about optimizing the order of the cuts. It gave great result and allowed my to push the speed closer my plasma torch's specs. So I used the Visvalingam-Wyatt simplification algorithm (I used it instead of the Ramer-Douglas-Peucker simplification). The first script was written to diminish the number of points on all the curves. But one day I thought that I could improve the gcode so I wrote some python scritps to make things better. I did use mainly Opencam to generate my gcode. It works great, I am really happy with it. Last year I have build the Lead 1515 CNC.
