I've loaded a DXF of a circuit I'm working on and trying to work my way through a simulation of isolation milling. Problem is, I can't seem to find where you set the size of the workpiece. The simulation defaults to this big chunk of metal which (of course) keeps stopping due to rapid gouge.
I know I'm just being dense and its probably sitting right in front of me somewhere.
On the NC Solid Verification screen you've got a checkbox for Automatic offset and a box to enter a value. This creates a stock size rectangle based on the part increased in XY by the value you choose. If the automatic offset isn't appropriate you can uncheck the box and enter the coordinates that define your stock size in the 4 boxes below (notice how they change when you change the auto offset value). There is also a box for Z top of job which is probably what you most need to tweak to match your stock to your geometry/solid. You'll get a rapid gouge because you don't have sufficient rapids clearance in the toolpath to match your Z top of job in simulate. Hope this helps.
