Depending on how your order was placed and processed, the oldham coupler may
be partially or entirely installed on the ballscrew.
These steps will need to be performed for all 4 axes.
Coupler Installation:
If the entire coupler is installed on the ballscrew:
1) Loosen the M4 socket head clamp on the motor half of the oldham coupler.
If the coupler is not installed:
1) If necessary, assemble the coupler by pressing the two metal halfs into the plastic
middle piece.
2) Loosen the two M4 socket head clamp screws in the oldham coupler.
3) Slide the 10mm half onto the ballscrew end until it presses against the shaft collar,
and tighten the clamp screw.
If 10mm half alone is installed:
1) Loosen the M4 socket head clamp on the motor half of the oldham coupler.
2) Assemble the coupler by pressing the motor half into the plastic middle piece,
then pressing the middle piece into the 10mm half.
Motor Installation:
1) Slide the motor shaft into the motor half of the oldham coupler.
2) Fasten the motor to the motor plate using the supplied fasteners.
