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! (starting a ways into the spiral instead of the start) couple of things. (initial runs) The Gcode program doesn't finish. http://imagebin.org/276743 the motion stops - but the vel shows 116ipm and the linuxcnc still thinks it is running the program. (the play button is pushed in) You can hit the stop button and re-run the program and is seems ok. but it still pauses at the end. Acceleration constraints. This seems better to me also. It gets better with a higher servo thread also (but the peak velocity doesn't seem to increase - I had though you had said that would happen...) 1khz http://imagebin.org/276740 - almost 40in/sec^2 (should not exceed 30) 5khz http://imagebin.org/276741 - 32in/sec^2 10khz http://imagebin.org/276742 - didn't actually look - but it looks like the spikes are less Now - I don't know if it gets worse (as you can see I don't have as much sample length at the higher base periods. ) I can also check for peak constraint violation also.. I think though that you are headed in the right direction! (that peaks at about 330ipm vs around 120ipm with current blending) Awesome work! sam On 11/12/2013 1:32 AM, Robert Ellenberg wrote: > The public folders aren't shared unfortunately, but I can create a private > folder shared between testers, with a public link if need be. > > The first batch of test logs and screenshots is uploaded as well, which > uncovered a few hints to the remaining acceleration issues.
