[05:18:50] <cradek> arcs are a problem and I asked stuart this same question just yesterday. seems the answer is it's 0 at the start of a full cirle, goes up go 2r, then back down to 0
[05:27:47] <cradek> so the definition is [xyz] coordinate of this move's endpoint - [xyz] coordinate of current location
[05:28:09] <cradek> and if that seems stupid for a certain move, you hum a tune and display it anyway
[05:29:48] <cradek> he also wholeheartedly endorses my simple plan to fix run-from-line once and for all
[05:30:05] <cradek> but for now ... goodnight
[06:38:23] <alex_joni> yay chris
