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

Hi Hood, on the machine in the vid I'm using 42.20. (never got round to updating it)

Coincidentally I have an eye on CV being "the problem". (or more to the point a MYTH about CV being the problem).

When Mihael asked me to post my xml I did a quick compare of mine and his. There's basically just one difference. I notice he has "Stop on CV angles > 89.9"

Mihael please turn this off (untick it in general config) and try your toolpath again.

Well I cant try that version as it will be too old for the CSMIO that I use and regarding your Stop CV, I dont have that enabled in my profile so possibly not that.

Yep - looking like you're absolutely right Hood. With 43.63 I get exactly the same problem.

Ok thanks, I am thinking it may be 022 or before that is needed, seems to after that version that a  lot of things got screwed up.
Dont suppose there is a chance of you trying 022? :)
