Friends CW has a Y Motor Issue (I think). After replacing the Y Motor and ready to start the first project...... Y Motor begins the "homing" process normally, but when the truck goes all the way to the left side to start the measuring process all comes to a stop. When the truck makes it to the end it doesn't stop and wants to continue moving causing bad clicking sound and we have to turn off the CW. Any thoughts? When all if off the truck moves side to side really easy with no issues.
