I just got my first gantry 4x8 CNC. So sorry for the newby question. When routing on the vac table. How do we ensure we don't damage the wood? when doing full cut throughs?

You will. All cutters need something to cut against which is sacrificial. Learning what depth does the least damage to the spoil board vs gets a great cut is one of the fine tuning items you need to work through.

Even on our Zunds, the blade cutting wears out the belt in time.

We have 4 routers that cut primarily acrylic, polycarbonate, and PVC. You will replace the spoil board , but you can buy a planing bit to remove the top surface as needed. We use 3/4" mdf and cut about .04 in to the board on each cut and it works well for us. We plane the board off as needed until it's about .20 thick and then replace it.

Years ago when we ran a Gerber 408, this is how we did it as well. Kinda cool using the router itself to plane the spoilboard flat again. Just makes sense.

FireSprint is a wholesale sign printer to the trade.
