- Arc mm_per_segment parameter was removed and replaced with an arc_tolerance parameter, which scales all arc segments automatically to radius, such that the line segment error doesn't exceed the tolerance. Significantly improves arc performance through larger radius arc, because the segments are much longer and the planner buffer has more to work with. - Moved n_arc correction from the settings to config.h. Mathematically this doesn't need to be a setting anymore, as the default config value will work for all known CNC applications. The error does not accumulate as much anymore, since the small angle approximation used by the arc generation has been updated to a third-order approximation and how the line segment length scale with radius and tolerance now. Left in config.h for extraneous circumstances. - Corrected the st.ramp_count variable (acceleration tick counter) to a 8-bit vs. 32-bit variable. Should make the stepper algorithm just a touch faster overall.
