I made a cnc router 500 x 700mm my control box is a Arduino sheild Grbl software . I have setup up the software for the nema 17 stepper motor the steps to 10mm for x,y,z and my Grbl Controller 3.6.1 which I load the Eagle gcode. All is well when I start the cnc router and the pcb is been routing but the board track are not right and is all out of place.
