Micro Precision Shim

Install the second precision micro shim onto the M5x50 screw

The assembly should look as shown, a micro precision shim on either side of the toothed idler

Fasten the M5x50 screw through the y_idler, into the M5 nylon lock nut

Check that the toothed idler rotates without binding. If the idler is difficult to rotate, loosen the M5x50 screw until the idler rotates smoothly
