[Emc-developers] normal.z=0.039370

Hi, when i do the ' g02 x2 y3 z4 r3' or other similar gcodes, i watch the 'normal' of the arc from TASK to MOTION, the normal always is 'normal.x=0.00 normal.y=0.00 normal.z=0.039370' , and the'normal' dont change at all. why？ Best regards.

If you try an arc in a different plane (e.g., G18 or G19) you will see a different value for normal. The specific value 0.039370 occurs because the normal vector is erroneously treated as a length and converted from mm to in. If you have encountered a bug that you are trying to fix, can you

Thanks,Jeff, no bug, it's my comprehension fault, What i wonder now is that how the LinuxCNC do a spherical 3D arc by G_Code or by other way? 2015-10-08 22:32 GMT+08:00 Jeff Epler : > If you try an arc in a different plane (e.g., G18 or G19) you will see a > different
