Z-axis truck-how do you tighten rollers

[allan eggert]

Has anyone had to take slack out of rollers. If so could you explain how?

The Z-Truck bearings to the rear of the machine have cam bolts ( well cam axles to be more precise) . You need a very thin wrench, like a bicycle wrench (around 13 mm I think) to adjust them. Slip the wrench around the hex shaped part of the cam axle and loosen ( clockwise while looking at the Z-truck ) a bit while holding the phillps scre in front. You can then turn the axel to take the play out. It takes a bit to get the hang of it as once you find the correct axel location you have to back it off a bit, tighhten up the screw and then move the axel back. This locks the axel tight to thw screw.

Thanks Jeff, That was pretty simple.
