In this step, you'll install and wire slots onto the front and back rails of your LumenPnP. Slots provide power and communication to your feeders.
Adjust Your Staging Plate
To ensure feeders will mount to your LumenPnP's front rail, we need to ensure that your staging plate is mounted at the correct position. If you have a v3 LumenPnP, your staging plate is already at the correct distance, and can skip this section.
Be aware that moving your primary staging plate will change where your bottom camera and homing fiducial markers are mounted. After moving the staging plate, you will need to review your machine's calibration. Specifically, the Homing Fiducial and Bottom Camera Position.
Unplug your LumenPnP.
Loosen the 4x M5x8mm button head screws that secure each staging plate to your machine.
Measure exactly 75mm of clearance between the front rail and the staging plate. You can use the squaring bracket included in LumenPnP v3 kits. (STL available in the latest LumenPnP Release)
Re-tighten the four M5x8mm button head screws to secure the staging plate.
Each slot has a number from 1-50. This is the slot's address. It's important that you mount slots in order. You'll also notice that the 50th slot is a different color. It's important that 50 is connected last in the harness. This allows the feeders to communicate correctly.
For slot number 1, take an M5x10mm socket head screw and insert it in the circular opening on the back.
Lightly thread an M5 T-slot nut onto the screw as shown.
Repeat this for each feeder slot.
Line up slots 1-25 in numerical order in preparation for mounting to the front rail.
Mount the Slots
Push the LumenPnP gantry to the back, right corner of the machine.
Lift the machine up onto its back legs.
Grab a Spool Arm from your feeder packaging. This print comes with each feeder and holds a component spool. It also has a notch for aligning slots.
Looking at your machine from the bottom, find the front left leg (in the air, on your left). Place the flat of the square end of the spool arm against the front left leg, and the back of the arm against the front rail extrusion. Use the image below for reference.
Insert the T-slot nut of the 1 Feeder Slot into the extrusion as shown, and slide it into the notch in the spool arm. Tighten the M5 screw to secure the slot. This notch places the slot exactly 85mm away from the front left leg.
Begin mounting the rest of the slots in order, with the same orientation as the first one. Gently press each slot into the previous one while tightening to ensure there are no gaps between them.
Continue until slots 1-25 are mounted to the front rail.
Next, you'll mount slots to the back rail. Near the back right leg, place the flat of the square end of the spool arm against the metal triangle bracket. Lay the flat back of the arm against the back rail extrusion as shown in the image.
As before, insert the T-slot nut of the 26 slot into the extrusion as shown, and slide it into the notch in the spool arm. Tighten the M5 screw to secure the slot.
As you did for the front rail, mount the slots in order in the same orientation as 26, gently pushing each slot into the previous when tightening.
Ensure that the differently-colored slot 50 is in the final position.
Install the Harness
If you have a cover on your motherboard, remove it by unscrewing the two M3x30 socket head screws.
Identify the feeder port on your motherboard. It's the 2x3 pin connector below the Y axis stepper driver.
Find the end of the cable harness with the ← TO MOBO label. Plug this end into the feeder port on your motherboard. Flip the cable over so that it's leading off the left side of the motherboard.
Remount your motherboard cover with the two M3x30mm screws.
Using the cable clips, secure the cable to the bottom of the left rail as shown.
Fold the cable over as shown, and secure it to the bottom of the front rail using two more cable clips.
Bend a small "U" shape into the cable in between each of the next 25 connectors as shown.
Plug the next 25 connectors into the 25 slots on the front rail.
Attach the cable to the bottom of the right side of the front rail using two cable clips.
Fold the cable over, and secure the cable to the bottom of the right rail using three cable clips as shown.
Fold the cable over again and secure to the bottom of the right side of the back rail using two more cable clips.
Bend a small "U" shape into the cable in between the final 25 connectors as shown.
Plug the final 25 connectors into the 25 slots on the back rail.
Take a minute to ensure that your wiring looks like the picture below.
