Step 2 Mounting the Stepper Motors
Step 2a Build six Idler Bearing Assemblies using
one M5 x 30 Machine Screw (H48), two
Flanged Bearings (H86), two Small Black
Washers (H89) and two Idler Fender
Washers (H50) in the sequence shown
below.
Be sure the head of the Machine Screw
fits against the Bearing flange and the
other is mounted so that both flanges
are oriented outboard from each other.
Step 2b Insert the threaded shaft of the Bearing
Assembly though the XY Stepper Motor
Mount (QR2), add Idler Fender (H50)
washer, and secure with a M5 Lock Nut
(H49).
