Thanks guys. I agree with Jay- I think the best way will be to implement Fusion 360 “project” 3D tool path and play with the spindle speeds to turn the laser on or off. Here’s the issue, there are only two places in Fusion to set the spindle speed: “Spindle Speed” and “Ramp Spindle Speed”. Even if “ramp spindle speed” is set to “0”, and milling is set to “0-255” as needed, the g-code is still going to activate the laser during lead-in, lead-out, plunge, etc… One hack I can think off is a clever macro to edit the g-code and reset any non-milling operation to zero so that the laser is only on during “cutting” operations. Another thought- I can try and make the “cuts” continuous, so that they link to minimize transitions. I can also make the transition heights as high as my machine will allow in order to defocus the laser. I’m not confident this will work because the focal depth of my laser is quite large. Fusion can definitely handle the x,y,z topographic changes. Last problem is, the files are huge and Fusion is horrible with .svg’s. Would be great if LightBurn offered an integrated solution.
