    I am running Mach3 Version R3.043.066

    Every thing is running fine, but there is a problem. when a program is running or the machine is idle, motors rotates randomly. The motion is for fraction of a second. This can happen any time even when the machine is not running any g-code. I am unable to identify the problem. Please kindly help.

    This will be electrical noise. Use shielded cable on all motors and signal cables and ground the shielding at one end only and take all grounds to a single point. Don't run single cables along side high power cables like Spindle power cable.

    Don't fasten signal and power cables together using cable ties.
