Hi Kev,

Looks good so far - should be nice and rigid with those large alu sections.
You have an interesting concept with the Z reaching to cut below the frame, do you have any sketches?

Next you need to decide where to put your y axis gantries, and how to mount your leadscrews and steppers.

When does your college project finish - a deadline is healthy! I wish CNCs were around when I was at college! :) (actually they were, but you fed code to them on punched card, not usb keys!)

Keep it up and keep us posted!
