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.

Import Board

1. Download the FTP board position file. It's titled ftp-top.pos, and can be found in 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, perhaps as ftpPCB.board

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. In the Parts tab on the top right, find the lines for the newly created components: LED_0603_1608Metric-LED_Small and R_0603_1608_Metric-R_Small. Set their Height values to 0.5mm by double-clicking the cell.

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

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.

Attach Feeders

Powered Feeders

If you purchased any 8mm Photon Feeders and would prefer to use them for your FTP, follow the steps for setting them up now, and then you'll come back to this guide to finish preparing for the FTP by setting up the board.

Search for Feeders on Boot

Every time you open OpenPnP, you'll have to search for your LumenPnP Feeders again to use them. Click the Search button in the Global Config tab in any PhotonFeeder in your feeder list to scan for feeders on your machine.

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 with the tape feed holes on the left. Slide the LEDs into the adjacent tray. Don't peel back the clear covering tape yet.

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

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.

   Feeder rotation value

   The Rotation field in feeder configuration sets the orientation that OpenPnP thinks the component starts at in the tape. If you find that your parts are placing with a consistent rotation offset, try adjusting this value (start with increments of 90 degrees) until your parts are placing with the correct orientation.

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.

Fine-tuning feeder height

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

2. Select the feeder you want to start with and 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 Z axis safely upwards, and then jog 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
