I think there is still an issue on how it picks calculates the max velocity for a move when there are slower axis's. Looking at steve.ngc again - if I make both x and y at 140ipm - and z is at 50ipm - it runs the whole profile at 50ipm (with a few short spikes faster..)
I could not log the whole run because of the speed.. http://imagebin.org/299492 Even if I have no z moves in the profile - it still runs mostly at 50ipm If I set the z axis so it is the same velocity - then it works as expected. (runs the profile at 140ipm) The current TP actually does better trying to get at the 140ipm - just a lot more jerky as it slows down for the blends.. it runs it quite a bit faster.. 18 vs 24sec http://imagebin.org/299491 thanks! sam On Wed, 12 Mar 2014 09:29:15 -0500 sam sokolik <sa...@empirescreen.com> wrote: > Yay!
