Curious, what does one do with 9000 of these?
What is the material? If it’s something like Baltic Birch, it might be worth contacting a local millworks with a 10’x20’ machine. Save money on materials, and a lot of time.
Otherwise, reducing retracts to the minimum safe height is about all you can do in something like Carbide Create. From a time perspective, it’s probably worthwhile to program this in a more advanced CAM environment. You will have a lot more control over retract policies and machine movements.
Each package has its own hiccups when it comes to jumping around, but they typically incorporate solutions to minimize or eliminate them with a little user fiddling. For a one off, optimization doesn’t really matter. 9000 is a decent run.
