I would recommend you consider a fixed gantry moving bed or high fixed walls for your Y axis that a low gantry rides on.

Thanks for the suggestion but I've come a long way to do anything about it. I'm fully aware of the short comings of a moving gantry CNC and if I had to do it all over again, I'd probably do a fixed gantry. I'll see how it goes.
A second machine won't be long after this guy is finished.
