By george35626/03/2017CNC Shield. This is a faithful copy of the V3.0 board produced by www.protoneer.co.nz There is some great info on this setup at http://blog.protoneer.co.nz/arduino-cnc-shield/ with a step by step at http://blog.protoneer.co.nz/arduino-cnc-shield-v3-00-assembly-guide/
One important thing - NEVER power up the board without there being stepper motors connected to each driver module. Failure to do this WILL destroy the driver modules.
