Installing Feeders

The FTP PCB has two different types of components that need to be placed: resistors and LEDs. Each will need its own feeder so that the LumenPnP can pick each type of component. For this guide, you'll use printed tray feeders.

Attach Feeders

1. Use two M3x10 button head screws and two M3 wingnuts to secure the printed tray feeder through onto the staging plate using holes: C15 and E15.

2. For each component, cut a strip of component tape off the reel about 125mm long.

3. Slide the Resistors into the left-most tray feeder, and the LEDs the adjacent tray.

4. In OpenPnP, connect to your LumenPnP and home it.

Import Board

1. Download the FTP board design. It's in the LumenPnP_PCBs.zip artifact on the latest major release.

2. Navigate to the Job tab in the top right.

3. Click that "Add" Icon button to add a new board and select New Board. Save the board in the same directory as the job.

4. Click on the newly-created board in the list to select it.

5. Go to File > Import Board > KiCAD .pos

6. In the Import popup:

   1. Select the ftp-top.pos file you downloaded earlier as the Top File
   2. Enable the Assign Parts checkbox.
   3. Enable the Create Missing Parts checkbox.
   4. Click Import

7. Go to File > Save Job As and save your FTP job.

Add Feeders

1. Navigate to the Feeders tab in the top-right pane.

2. Click on the "Add Feeder" icon button.

3. Select ReferenceTrayFeeder and click Accept.

4. In the lower-right panel, you'll be in the Configuration tab. Change the Part to be R_0603_1608Metric-R_Small.

5. Set the Y Offset to -4. This is the space between components on the tape.

6. Set the Y Tray Count to 30. This is the number of components available on the feeder before it needs to be manually moved forward.

7. Set the Pick location to: X=45, Y=175, Z=20 as a starting point.

8. Click on the "Position Camera" icon button to move the top camera roughly over the left feeder.

9. Position the center of the top camera feed over the center of the top-most slot holding a resistor in the tray. You can drag the reticle in the camera feed, or use the jog buttons.

10. Zoom in on the camera feed and precisely position the center of the reticle over the center of the slot holding the resistor. The resistor itself may not be perfectly centered, that is fine.

11. Click the "Capture Camera Location" icon button to save the XY position of the start of the feeder.

12. Click Apply to save the feeder settings

13. Click the Enable checkbox in the feeder list.

14. Do the same procedure again for the LED feeder. You'll assign the part LED_0603_1608Metric-LED_Small to the new feeder.

Installing the N045 Nozzle

1. Grease the nozzle holder before installing the N045 nozzle.
2. Install your N045 nozzle onto the nozzle holder.
3. Wipe off any excess grease.

4. Go to the Machine Setup tab in OpenPnP.

5. Navigate to Heads > ReferenceHead H1 > Nozzles > ReferenceNozzle N1.

6. In the lower-right pane, switch to the Nozzle Tips tab.

7. For row N045, check both the Compatible and Loaded checkboxes. If you haven't set up automatic nozzle changing, you will receive a popup saying that you're required to manually load the nozzle on the toolhead.

8. Go to the Packages tab in the top-right pane.

9. Select LED_0603_1608Metric from the list.

10. In the lower-right pane, you'll be in the Nozzle Tips tab. Click the Compatible on the N045 row.

11. Similarly, select R_0603_1608Metric from the Package list.
12. And click the Compatible checkbox on the N045 row.
13. Under the bottom-left Machine Controls pane, select Nozzle: N1 - N045 (Head:H1) to enable the left toolhead.

Fine-tuning feeder height

1. Navigate to the Feeders tab in the top-right pane.

2. Click on the "Position Nozzle" icon button to bring the nozzle over the feeder.

3. Use the Jog controls to lower the Z axis until the nozzle is touching the surface of the plastic tape cover.

4. Click on the "Capture Nozzle" icon button to save the new Z height of the feeder.

5. Jog the XY gantry away from the feeder.

6. Remove the tape cover from the feeder.

7. Click the "Pick" icon button to pick a component from the feeder. If the component is picked up properly, your Z-height is correct. If not, you should:

   1. Lower the Z height of the feeder by 0.1mm
   2. Press Apply to save the change
   3. Home the machine
   4. Try picking a component from the feeder again.

8. After you've successfully picked a component, in the machine Machine Controls pane, switch to the Special Tab.

9. Recycle the component you've successfully picked up

10. Copy the final Z height, select the other feeder, paste it for the other feeder, and press Apply

11. Test picking a component from the other feeder
