Step 1: Add the cable carrier mount

Attach the 60mm cable carrier mount to the cross-slide plate using two M5 x 16mm screws and M5 flange locknuts.

Step 2: Mount the vacuum pump

Attach the pre-assembled vacuum pump subassembly to the cross-slide plate using two M5 x 16mm screws and M5 flange locknuts.

Then connect the inline air filter and vacuum pump tube between the pump and the tube coming from the Z-axis cable carrier.

Step 3: Slide the cross-slide onto the gantry main beam

In order for the cross-slide to slide smoothly and wobble-free on the gantry main beam, you must adjust the eccentric spacers of the bottom two V-wheels. Adjust the eccentric spacers using the eccentric spacer adjustment reference guide.

Then slide the cross-slide onto the gantry main beam from the side opposite the electronics box.

Step 4: Feed and secure the belt

Secure one end of the short belt to a belt clip using a belt sleeve and then attach the clip to the end of the gantry main beam using two M5 x 10mm screws and a 20mm nut bar. The tab of the belt clip should be oriented towards the front of the FarmBot. Refer to the belt installation guide for reference.

Feed the belt under the first V-wheel of the cross-slide, then over the pulley and under the remaining two V-wheels. The flat side of the belt should be in contact with the V-wheels while the toothed side should engage with the teeth on the pulley.

Secure the belt at the other end of the gantry with another belt clip, 20mm nut bar, and two M5 x 10mm screws. Ensure there is a small amount of tension on the belt once everything is in place.

Step 5: Attach the cable carrier

Lay the y-axis cable carrier onto the horizontal cable carrier supports on the gantry main beam such that the end with the 90-degree connectors will connect to the cross-slide. Attach the cable carrier to the 60mm cable carrier mount using two M5 x 16mm screws and M5 flange locknuts. The screws should thread firmly through the cable carrier end piece.

Step 6: Connect the water tubing

Push the y-axis water tube onto the 90-degree barb and the NPT to barb adapter on top of the solenoid valve.

Step 7: Connect the cabling

Connect the Y vacuum pump cable (VAC) to the vacuum pump.

Connect the Y-axis and Z-axis sections of the UTM cable (UTM) together with the 12-pin connectors.

Connect the Y-axis and Z-axis sections of the following cables together:

• ZY encoder cable to ZZ encoder cable with the 7-pin connectors
• ZY motor cable to ZZ motor cable with the 4-pin connectors
• Camera (CAM) to camera cable (CAM) with the 4-pin connectors

Ensure you fully inserted the 90-degree connectors together. This may require a multi-step process of pushing together, slightly tightening the thumb screws, pushing together again, and tightening some more.

Step 8: Connect the y-axis motor and encoder

Connect the Y motor cable and Y encoder cable to the y-axis motor and encoder.

Step 9: Remove slack

Reduce the amount of extra tubing and wiring between the y-axis cable carrier and the z-axis cable carrier by gently pulling any extra cable or tubing length through the y-axis cable carrier. It can be difficult to coax the contents around the bend of the cable carrier, so take your time and ensure that you are not pulling anything too hard.
