Thanks all-
LR- It is still in the planning stages- As soon as I finish the gantry design, I'll order the framework. I've got the go-ahead from the boss, so I've got to start burning the money.
I started drawing it up with a 12" Z travel, which makes a minimum Z platform that is 18" high (along the Z axis) that means I need slides that are 18" long too. So when the bit is all the way down, the Z platform is extended from the gantry 12", putting the router out on a 12" long arm to wobble around on.
I'm concerned that I'll give up a lot of accuracy unless I make a big beefy support for the Z.
Anyone have some more pictures of a home-made Z with around a foot of travel?
I'll be mostly cutting 1/4" to 1" acrylic, but want to keep the options open for becoming a general purpose CNC shop.
