A problem has been reported on the bug tracker, regarding some (valid) G-code from FreeCAD which features an arc of very large radius.
I have created a simple test file to show the problem. G0 X1 Y -1 G2 X1 Y 1 I 2000000 J 0 F1200 m2 If the I number is 1,999,999 (ie, one mm less) then the preview is correct, but at 2,000,000 the preview is wrong (but the motion is right) Between 2,000,000 and 2,000,022 there is a warning about out of bounds, but the motion is correct. So in this region the preview interpreter and the real interpreter differ. At 2,000,023 the actual motion is _also_ incorrect. This can be tested in the axis sim, and seems to be the case with v2.8 and master. -- 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-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
