 Arc output tolerance

When enabling arc output, XY, XZ or YZ, how is the tolerance VX decide it's an arc or not?
Is it toolpath tolerance?
Thanks a lot for any reply and/or informations about it.

Hi Hans

The developers will need to answer that one for you - I doubt that it is only a tolerance issue but of course there must be some degree of tolerance in the equation. There are other factors if you are concerned about arc output from QuickMill.

Roughly speaking toolpath tolerance decides if a bunch of points can be interpolated by an arc or not. It was a problem in QM until version 0.24.0 that sometimes bad arcs where fit so a bit of extra care should be exercised with older QMs.

Nothing really serious. Arcs are working under tolerance pretty well in QM for more then 2 years now I think a lot of guys reading this post are using them currently. Unfortunately we had a minor gauge in 1 part that we fixed around 24.0 version so I recommend people to evaluate and simulate the path always before cutting it with or without that fix. Is better to be safe then sorry.

Screen captures for what bobf4fun? A path with or without arc interpolation is looking the same or this is what we really hope to happen

I suggest to use arc interpolation only for Z Level or lace cycles with 0 or 90 degree rotation angle. Forcing them on other parts is really not a wise decision.
