My stepper motors work great until i enable the limit switches. It's nothing to do with the switches because it still does it when there disconnected. When i jog in one direction it starts to move for a random distance than stops untill i press the jog button again. But it works great with the limits disabled.

Your probably getting noise from your motors onto the limit inputs. Try using a noise clamp like these: http://www.kellyware.com/kwforum/discus/messages/5/796.html
