I have had to change a couple of items in the Marlin Configuraton.h files without problems; however, all three axis move about 20mm when I use the 10mm movement from the LCD controler. I have changed #define DEFAULT_AXIS_STEPS_PER_UNIT { 200, 200, 800, 200 } //MPCNC but that results in no change in movement. What is causing my change to be ignored?
