I'm new to CNC and need help. I'm running Grbl1.1.f and Candle 1.1.7, my isue is that my Work coordinates is showing 500,400,26.141 and my Machine coordinates is showing 0,0,0 when I set ZeroXY it changes Work coordinates to 499,399 , machine coord remain zero in xyz and if I jog in any direction the coordinates on both Work and Machine do not change.
