Would this concept work?

[amd7000]

Hello again. Just been playing around with an idea in sketchup, probably not that good but think it will help me understand the do's and don'ts from your observations if that's o.k. The drawing is utterly carp, I've only used sketchup for a hour or so. That's my excuse anyway. ha ha.

I want a cutting area of at least 600mmx900x200mm. I think this design should easily do it? I would also like to run the 2 ball screws (1610 1.2m) on pulleys under the bed with 1 stepper to keep them clean and out of sight to make a tidier looking machine also. Is this o.k to do or wont it work that well?

The dimensions of the drawing are approx. 1.35mx0.9m. The height from the bottom of the frame is 490mm. I would use 120mmx60mmx3mm for the main frame and top of gantry. I would use 80x40 for the lower section of the gantry that is connected to the ball screws.

Any help would be much appreciated. Thanks
