+# 5. Check the shaft coupler for slipping
+
+The aluminum [[shaft coupler]] connects the Z-axis [[motor]] to the [[leadscrew]] to allow FarmBot to move in the Z direction up and down depending on the rotation of the motor.
+
+Check to make sure that the shaft coupler is not slipping as it transfers rotational power from the motor to the leadscrew. If there is slipping, tighten the screws on the coupler. You may optionally use blue Loctite to prevent the screws from loosening over time.
