i have an answer and a question.....
MJR: there is a new post processor in VCarve Pro that outputs true arcs instead of lots of little linear moves. i spoke with Brian and he allowed me to download a beta. it seems to help me. i am having other issues on my mill so i cant tell you for sure if it will be a total cure for you.
Mach experts: it seems that you can select constant velocity for the "soft" curves and set a limit to CV for "hard" corners. the Setting tab looks like it allows this, but the actual values are not clear to me and the mach document help was not much help. can anybody clear up what each of those settings do? the default angle is 180 which seems odd, and there seems to be a multiplier of some sort, defaulted to 1. any help would be great.
