Thanks for all the replies guys
Typical size that i am machining is around the 400mm by 300mm x40mm and that would be a clock face and yes it does have a good bit of detail on the front but not really an intense detail as its only for my bar and am a good distance away from it , typical tooling used is a 6 mm endmill and a 3 mm ballnose .
I think i should try what routerdriver has suggested and look at layering and tiling the job and especially when i start the wall art panel for the Bathroom wall , i was just wondering if it was ever possible to expand the memory on the machine.
By the way guys i have an amount of English yew slabs that has been in the dry for a few years 40mm thick and one piece is about 1.5 mtrs long by 350 wide if you have a use for it , i don't want anything for it just have it but you need to collect from Gloucestershire.
