this is the splash screen running.. Z is the only axis that doesn't obey the 30in/sec^2 limit http://imagebin.org/276777
The spiral - goes over the limit. http://imagebin.org/276778 Here is a halscope of one of the overshoots - it is a ways into the spiral.. http://imagebin.org/276780 This is at 1khz.. 10khz - you seem to get about the same overshoot - about 43 - 44 in/sec^2 on the spiral and now - setting the feedrate override to 120%... :) (it had to be done) http://imagebin.org/276779 sam On 11/12/2013 7:50 AM, sam sokolik wrote: > Very cool!! > > This motion is much better than the previous release. > > I am not seen the odd start motion that I was seeing before - Nice > work!
