replicapro,
It seems there may have been some damage caused when the fuse went in the first place. One thing to check as I have found is to take off the cover on the top of the Z axis, loosen the drive belt of the motor and remove the tensioning plate. Some times what can happen is that the tensioning plate can foul on the pulley at the gearbox end, if you have a look around the clearance hole on the tensioning plate you may see a wear mark where it has been fouling, if this is the case what has probably happened is that the pulley has heated up and overloaded the motor, you may have been lucky that the speed controller went as it an easy replacement to get under warranty, in my case this problem burned out my motor.
