I’m new at this, so perhaps this is obvious, but working on a spoilboard for an SO3 XL.
I plan on milling an MDF spoilboard and adding threaded inserts into the backside, but how do I mill the SO3 base itself? I found this doc online (https://docs.carbide3d.com/tutorials/project-wasteboard/) but it doesn’t explain how to mill the holes into baseboard and not hit the center frame support strap. I can leave an onion skin there, but being new at this, that seems like a dicey first project to get right.
Any suggestions? Do I just span the center area with no wasteboard hold-downs? Do you just use self-tapping screws to anchor the wasteboard to the machine base and not worry about CNCing any thing other than the center points?
