Re: [Emc-developers] Help to fix a minor bug in circular trajectory planner

2007-04-12 Thread Mario .
The EMC2 manual says not to rely on ARC generator, probably also that relates to CIRCLE. I just wonder whether defining "circle" as a 360-line 360-tangle would help the trajectory planner. There are some principal issues with the trajectory planner. The planner cannot setup itself :( I spent hours

[Emc-developers] Help to fix a minor bug in circular trajectory planner

2007-04-10 Thread Xuecheng Xi
Dear Developers, mostly to Cradek: The trajectory command for a circle is not really a circle. The higher feedrate, the bigger the radial contour errors are. When I run the G-code (feedrate=100mm/s, radius=40mm) G2 x40 y0 i-40 j0 f6000, I record the trajectory comands rx and ry from axis.0.motor
