WHAT.!! . . . Are you for real.! Your going to waste money laser cutting steel templates to build a machine made from PAPER.!!

For the price of the laser cutting/templates you could buy all the steel needed to build the frame and have 50X stronger machine. Bolt it together if you cant weld or have someone weld it for you.

Also can I just say you are going about this all wrong regards the electronics. Roy's stuff is ok but it's more suited to smaller machines like Mills not routers. This is because the drives are low voltage with a Max of 40Vdc I believe. Routers run much higher feed rates than mills so we need more speed from the motors and steppers get there speed from volts. 40V max drives will be restrictive to a router machine unless you use a high pitch ball or lead screw and this will lower resolution so your getting a unbalanced machine.

Trying to cut costs on electronics is asking for trouble and never ends well.!!
