So in marlin my extruder won't move but in repetier it moves perfectly.
It isn't a temp issue, i have it at 200C while trying to move it.
If i move it in marlin by 1mm it moves but if i move it by any more it won't move.
Also i can't move my extruder through any software like pronterface or mattercontrol.
I can upload my marlin and repetier firmware if necessary.

Any help would be much appreciated.
