I do a lot of 3D carvings, and I rarely encounter this "raster disaster" that you speak of. It seems to me that you have a solution, and are in search of a problem. Unless someone knows of a perfect solution, I'll write a python script that achieves the ideal solution: Raster Disaster GCode comes in, Good Raster GCode comes out The way to achieve this would be to post-process the GCode. The ideal solution to this problem is a special raster: Go all the way up on the right side, rapid to the left side, and go all the way down, rapid to the right again. A way to solve this problem is generate 3D finish for the outer square, and delete the GCode for the inner square that I don't want to machineĪnother obvious solution is to do a second run at 90 degrees, to take care of these pesky shavings. It will split the work into 2: One half is in the right direction, the other half is in the wrong. Do a 3D finish in a selection of 2 vectors (Square-within-a-square). Vectric this quirk where half the time it goes in the wrong direction. 1 - Witness marks, and 2 - I'm limited to a very simple vector choice. The obvious one is to do 3D finish on offset mode, but there are 2 problems: with it. There are solutions to this problem, but none of them are perfect. When you conventional, the wood grains are carved away, but leaving them connected at the end When you climb, the grains get shredded and chopped. This problem is entirely a climb/conventional issue. This problems happens no matter what overstep % I choose, and no matter the tip size of the engraver. Or else, shavings/grains are still attached to the piece. When I do 3D Finish with an engraver, I want to avoid the Conventional direction at all costs.
