I played with lookahead and kernel frequency, but with no results. Ian, would you please, if it's not too much trouble, post your settings xml file, so I can do the comparison ? BTW. your machine is quite impressive, handling theese feeds and accelerations with no vibrations (being built from alu extrusions, if I'm seing right) - do you have build/specs thread ?
I ran test one more time with 0.3G accel, and though I cannot see that machine slowsdown/stops, I can feel it if I touch the machine frame. So, my theory about low acceleration causing CV to fail is not correct. Also, I presume that PC is fast enough, since Ian is getting good results with slower PC.
Thanks,
Mihael
