One of my two Y axis belts broke and needs to be replaced. Is there an easy way to replace the GT3 belt? The gear and belt are constrained between two aluminum plates which restricts access to fixing the problem. My fingers are unable to reach the belt or the gear to form a loop in the belt. Also I tried using wires, string, coat hangers, a screwdriver, hemostats, etc without success. Is there a simple solution to this problem or do I have to disassemble the majority of the machine to replace one Y BELT? Thanks Curtis
