Rotate the turret to Pocket 1

Remove the covers to access  the turret motor coupling.

For SL and HL machines, remove the covers as follows:

• Remove the rear cover [1].
• Remove the (3) screws [2], as shown.

• Remove the top wiper [1] and the wiper on the left side [2].
• Remove the screws for the cover [6] as follows: Remove the (5) screws across the top [3]. Then remove the (3) screws on each side [4]. Remove the screw [5] at the lower left side.
• Remove the cover [6] from the rear of the machine.

This Step applies to ST-10

• Remove the covers in the sequence shown
• Remove the covers [1, 2, 3] at the rear of the machine. 
• Remove the covers and wipers [4, 5, 6] near the right side of the turret.

 Note: A wiper [4] is on the top, and a wiper is on each side [4].

Make sure a minimum 1" (25 mm) space is between the turret and all objects in the direction of the Z Axis.

Using M43, Unclamp the turret.

Push [EMERGENCY STOP].

Use the screwdriver or your thumb to turn the coupling to get access to the coupling screw [1].

Loosen coupling screw for the collar on the side near to the motor.

Use a screwdriver or your thumb to turn the coupling to turn the turret in the next step.

Turn the coupling until the turret is at the tool pocket 1 position.

 Note: A "1" mark is engraved on the turret at the tool pocket 1 position.

Align the coolant nozzle with the coolant port, as shown.

Push [RESET].

Change Setting 7 to OFF. Change parameter 43:4 (Z CHANNEL ONLY) to 1.

This causes the zero channel of the motor encoder to set the zero position when you push [ZERO RETURN] and then A in the next instruction.

Release [EMERGENCY STOP].

Push [RESET]. Push [ZERO RETURN]. Push [A], and push [SINGLE]. This aligns the electronic zero channel with the mechanical home switch position and clamps the turret.

Manually turn the coupling to the left and to the right to feel the distance of the free movement. Turn the coupling to the approximate middle of the free movement.

 Note: If you cannot turn the coupler with your hand, use a flat-head screwdriver to turn the coupler.

Hold the coupling in the middle while you torque the coupling screw to 15 ft-lb (20 Nm).

Change parameter 43:4 (Z CH ONLY) back to 0.

Change Setting 7 back to ON.

Verify the backlash in the coupler by rotating the turret to several pockets

At each pocket place press [EMERGENCY STOP].

Verify the coupler moves an equal amount in each direction for each pocket checked
