Stepper motor missing steps? http://www.instructables.com/answers/Stepper-motor-missing-steps/ http://www.instructables.com/static/defaultIMG/default.SQUARE2.png http://www.instructables.com/static/defaultIMG/default.SQUARE.png http://www.instructables.com/static/defaultIMG/default.SMALL.gif jg156 Hi, I'm running a CNC machine using Mach3. After running some GCode, a stepper motor appears to have missed some steps. The Z-axis has shifted (a reference point has changed coordinates.) No apparent visible changes, so I assume the stepper has skipped. What can I do?
