Peter,
I believe Ah ha supports tool radius compensation while I don't believe any
of the others including Flash CNC do not. For my money I wouldn't consider
any system without tool radius comp. I always program everything for its
exact size then apply compensation for the tool I using. Makes it real easy
to make accurate parts, cut the first piece, measure it, adjust comp if
needed, the second one is dead nuts on.
