When a project is finished the Z truck moves to the far left. To remove the bit I've been sliding the Z truck to the middle by hand. To grab the truck you have to get your fingers around the metal frame and exert quite a bit of pressure to slide the truck to the center. It would be nice to have the machine move the truck to the center when a project is completed like it does when changing bits. Bye the way should the machine be turned off prior to sliding the truck?
