Orderd this few weeks back took time to get here from Germany but it got here Friday it came in 3 packages and I'm still waiting on the spindle but I have assembled machine and configured Mach 3

problem im having is the x axis moves random direction when jogging , and sometimes does not move atall just a quite humming noise , I've tried swapping leads round and it seems same so it's not drivers as all axis are configured same anyway, has anybody else had similar issues , I've taken some video that I'll try and upload tomorrow when Internet runs faster and I can upload , but what would make a stepper move random directions

can anyone help me resolve this
