Wow, a brand new machine and you're expecting problems already? Give it a chance.

I'll be curious to watch this thread. I'm actually trying to talk my 'day job' employer into buying a GR512 or GR712 with the 'extended Z' option.

I finally heard of a local guy who has been successful at using one to mill, drill and tap large aluminum plates. It's no powerhouse and it will only hold tolerance when used within its limits (due to flex in such a large but lightweight casting) but it's very capable of it.

What are you guys going to be doing with it? Patterns? Milling? Drilling? Get it with the aluminum table so when enough people screw up, you can just unbolt it and buy a new plate of aluminum, face it and start over.

I think it's a very cool machine and a lot of capability for the cost.
