I had this problem with EMC2 and after checking things for the 50,000 time it turned out to be a bad contact on a motor wire. Suggest you loosen the screws on that motor, take them out, re twist or solder the ends and put hem back. Worth a tryIf the nagging gets really bad......Get a bigger shed:naughty:

hi
found it at last one of the motor wires , going into the terminal block on the driver was under the spade screw instead of between it although to the touch the wire felt solid it wasnt a good electrical connection , wire in right place everything ok now ... for some thing so simple its been a right pain in the arse
