The BIG advantage to extending the Y axis outside of the x axis--you don't loose the space occupied by the motors, gearing, etc on your work surface. You'll still loose that floor space in the overall footprint. System2 isn't a pipe design - but you can see an approach to supporting the y axis there too. (Photo gallery) Hope that helps some - cheers Jim
Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
