This is my 400 mm x 360 mm CoreXY laser motion system using the parts from nagilum and some of my own.
It's based off Ramps 1.4 and DRV8825 Drivers with Reprap Discount Full Graphics Display. It runs Repetier firmware in Laser Mode.
I've tested it with Repetier Host as well as LaserWeb and motion works fine.
I'm using a rewired ATX 500W PSU to get power for Ramps and hopefully soon an 8W laser.
Thanks to nagilum for the parts.
