There will be resistance from magnetic forces while moving onto the
bearing pucks; this is normal.
6. Attach the carriage assembly to the bearing pucks.
7. Measure the gap between the motor and magnet by using plastic shim
stock.
The gap should be 0.79…1.70 mm (0.031…0.067 in.). If the gap is too

the gap is too small, machine the carriage or place shims under the bearing
pucks.
