Nice catch, Sam! those variables definitely should have been doubles, not ints. I'm not sure whether the comparison numbers Andrew posted were for the lines or arcs example, but it looks like 2.7 is at least competitive. 3:04 is second place on that list!
It surprises me a little that Mach3 isn't higher on that list. I wonder what lookahead setting they were using? @Andrew, I'm taking a look at the current velocity display issue, I think it will be a simple fix. -Rob On Sun, Mar 8, 2015 at 6:53 PM, sam sokolik <[email protected]> wrote: > 2 screen shots arc/line...
