THANKS FOR ANY HELP - and not flaming me. New to CNC routers as well as ShopSabre. Bought a used 4896 and was told by seller that SHopSabre gives lifetime support but now found out - just to original owner. Bummer for me. Working step by step to get up and running. Photo attached. Could someone please tell me what type of boards should be used here? The "machine" (?) board was not attached and the spoiler board is simply sitting on top. Can someone tell me what to buy for the bottom ("machine"?) board and how to attach it? What size? Thanks for any help!
