So everything’s working now?
EDIT: I just tried to replicate what you saw. When you change the BIT unit from inches to mm or vice versa, Easel does not convert the measurement. You’re probably seeing a difference in toolpaths of a machine “thinking” it has a 0.13mm bit when you actually have a 0.125in bit. That said, I think you’d see it a couple mm bigger, not smaller. Anyway, instead of guessing, I’ll let @JoeSimone tell us what he noticed.
