While cutting 3d models on my s3xxl I often get these grooves throughout the workpiece. Many times they show up in my toolpath preview on aspire. So I think that tells me they aren’t from mechanical problems.
I see these created while my 1/8" ballnose continually climbs next to each pass. Running a 10% stepover at something like 160ipm 40 plunge, after running a clearing pass and a .25 ballnose. So the 1/8 ballnose isn’t really clearing that much material. It makes me think this has to do with the direction the cutter is contacting the wood, not deflection.
I would think cutting profiles around individual components may help? I’ve done this on some projects with a slight offset in, with some success. I’ve had to deselect some 3d components and set the depth of pass to 0" prior to calculating each profile toolpath.
Problem is I don’t have individual components broken down on many STL files. They are all combined into one file.
Any ideas? Thank you in advance! Here’s some pics:
