One issue is that the current LinuxCNC trajectory planner only blends in XYZ, and any movement in an extruder axis will tend to cause a fall-back to single-segment blending. Combine that with the fact that STL files can only ever produce straight line segments, and high-quality STL use very small triangles, and the TP performance can be unspectacular. There is a full 9-axis blend TP out there, I think that Machinekit has it. It would be very nice to get that in to LinuxCNC, but with JA changes in LinuxCNC and not (AFAIK) in Machinekit, the code paths have rather diverged. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
