terminal block on the g203v

[woodman08]

I started having trouble getting the z axis to move ,checked for loose connections etc,drives all showing green light and motor stiff when power is on ,so its a control problem,After much looking around all the wiring it turns out its the terminal block toch it and the z works momentarily so i pulled the terminal block (2of) and put it back on and the z is ok,should these contacts be cleaned
Gecko is sending me some new blocks
