I am curious what the Hypermill folks would suggest? Do they have a FAQ on their website or a support forum?
Open Mind is a very secretive company. The only way I can ever get any questions about Hypermill answered is to contact Alan Levine who runs US operations for Open Mind. Nice guy. No BS. Very knowledgeable.
There is a Hypermill forum on CNC Advertising Zone but it's worthless.
