    Are you using the PC power supply to run the motors!?

    Re: stepper motor jamming

    No, they are different electric circuit... The only connection between is the parallel cable ... !!! Now its OK but I still have the problem when I'm jogging the motor stuck ... (All the axis), I find a solution ... If I press tab in mach 3 to open the pendant then I can jog from the keyboard or mouse without problem, but if I close it then I can't move the axis .. Its homing without problems ... What could be the problem ?!!
