Awesome, Ill stay away from 3D printer electronics then :)

'If running very long 3D work(15hrs+) then I prefer twin belts as you know one motor can't run out of sync with other' By this do you mean the single motor system?

Here is the machine so far, The gantry side are completely different though the Y axis section is similar with some ugly looking supports, Might do what another member said about one 40x80mm piece running the length... Also still need to add laser cut steel peices for mounting the ballscrew supports at either end of the X axis...Pay no attention to the other side of the machine...I mate everything on one side then mirror and remate on the other...saves inserting the same parts over..
