Two thoughts: First: I had a joint following error which occurred because the machine was trying to exceed acceleration limits for the axis. Those limits were set in the ini file, so I edited that and eliminated the problem. But I can't see how that would happen if you have not recently altered the ini file. Second thought is: Can you disable the automatic axis zeroing cycle, and just use manual home setting, and see what happens? That way, the machine should not even attempt to move any axis until you home them all manually, by clicking on the Home button, and not actually moving the axis. Then you can jog each axis individually. You can also move each individually at various speeds for various distances and see what happens.
