All linear axis coordinates (XYZ) are in millimeters and rotational axis such as C and D are in degrees.
Download and install OpenPNP.
Download the latest machine.xml for the Rapid Star and replace it with the default one. Make sure OpenPNP is closed while doing this or it will overwrite the file when you close it!
Navigate to Machine Setup > Drivers > Gcode Driver Rapid Board > Configuration. Select the port for the machine and baud rate 115200 and click Apply to save the settings. Check that you set up the connection to the Rapid Board correctly by clicking the power icon . The machine should turn on and the home icon should appear yellow to indicate that the machine hasn’t been homed yet. Don’t home it yet!
Note: You need to first power on the machine before you open OpenPNP so that it can detect the cameras. OpenPNP does NOT detect new cameras after it has already been opened. Therefore, before you continue, make sure your machine is on and re-open OpenPNP.
The jog panel is where you control the machine’s peripherals directly. You can:
The digital readouts show where the selected nozzle is located in relation to the machine’s coordinate system.
The Camera View Panel is where you can select which camera you would like to look at or alternatively view both cameras at the same time by splitting the view horizontally or vertically. You can choose the different views via the dropdown list on the top. Additionally, you have the option to adjust the crosshair options for the specified camera if you’d like by right clicking anywhere inside the camera view to bring up the options.
With OpenPNP installed and the machine settings loaded, now is a good time to check that your machine is properly connected and functioning before we move forward with calibration. Here is a list of checks to perform:
Note that if you do end up connecting the Rapid Star to a different USB port on your computer, the camera device settings are lost and you will need to set this up again. It’s recommended that you set this up on a USB port that you intend to use permanently!While most of the Rapid Star’s settings have already been pre-configured for you, we still need to calibrate it. Navigate to Machine Setup tab > Downward Cam. Select the camera on the head and choose the same 1280 x 720, 30FPS, 1bmd resolution settings as shown in the image below. Make sure all the settings for the specific camera such as brightness, backlight compensation, contrast, etc. are the same as those listed under the default column and click apply to save the settings. Check that you selected the correct camera by waving in front of the camera and seeing if it shows up on the dashboard to the left when the downward cam is selected.Do the same for the Upward Camera listed under Machine Setup > Cameras.
Next we will capture the position of the cameras. We will start with the upward looking camera. Home the machine and then jog the selected nozzle (XYZ) so that it is perfectly centered and in focus over the camera. Navigate to the position tab under Machine Setup > Cameras > Upward Cam > Position and click capture nozzle icon. You will see the location coordinates update.
Activate the vacuum pump by clicking on actuators on the jog panel and then turning it on. Attach the PCB that was included with your kit labeled “Lens Calibration” to a 508 nozzle on the head so that the nozzle sits in the center of the circle as shown below, at the same 45 degree angle, ensuring it faces towards the right side of the machine.
Go to Machine Setup > Drivers > Gcode Driver > Console and send the following command:
The star will then proceed to pivot the PCB around the upward facing camera and will capture multiple images to calibrate the lens. You will see the screen flash multiple times in OpenPNP when a picture is taken. When the process is complete OpenPnP will enable the undistort function and if all went well your camera view should now appear undistorted. You can toggle the “Apply Calibration” checkbox.
Next we will do the same for the downward looking camera. Take the PCB and hold it in your hands so that the fiducial pattern faces the upward camera. Click Start Lens Calibration and move the PCB around under the camera at various angles until it finishes capturing all the pictures. Make sure all the fiducials are visible in the camera view. Toggle the Apply Calibration checkbox and click Apply to save the settings.
Home the machine and then navigate to Machine Setup > Cameras > Upward Cam > Position. Click the position nozzle icon and the selected nozzle will move above the Upward Camera. Attach a 508 nozzle to the side facing the Upward Camera. Turn on the vacuum and attach the Calibration PCB to the nozzle facing the camera so that the 5×5 square is visible on the camera view as shown below.
Next go to the Camera Configuration tab, enter 5 for Object Dimensions for both X & Y and click Measure. Position the dashed line over the square as shown below and click Confirm. The Units per PIxel should have now been updated. Click Apply to save the settings. This sets the pixels per mm for the Upward Camera.
The Downward Camera gets calibrated the same way. Place the calibration PCB you just used on the conveyor belt so that the 5×5 square faces up. The Calibration PCB should be pushed up against the conveyor with the gripper so it sits at the proper Z height. Jog the head so that the camera is above the PCB and the 5×5 square is visible in the camera view. Next, navigate to Heads > Cameras > Upward Cam > Camera Configuration. Enter 5 for both X/Y and click measure. Position the dashed line over the square and click Measure. Then click apply to save the settings. This sets the pixels per mm for the Downward Camera.
We now need to tune the camera offsets in X/Y to the selected nozzle. With the Calibration PCB from the previous step still in the conveyor, choose the N1 Nozzle from the jog panel dropdown, load a #503 nozzle and slowly jog it so that it sits in the center of the PCB’s fiducial, touching it (don’t forget you can adjust the jog distance so you don’t crash the nozzle into the pcb). After you have done that, double check visually that the nozzle sits exactly in the center of the fiducial in X & Y. This is important. Then navigate to Machine Setup > Heads >ReferenceHead H1 > Nozzles > ReferenceNozzle N1 as shown below and click Store nozzle mark position.
After the nozzle mark position X & Y coordinates were updated, click the park icon for the Z axis to home the Z. Now jog the downward camera so that the crosshair is over the fiducial. Make sure to carefully align it in the center and click Calculate nozzle offset. The Nozzle head offsets will then update. Click Apply to save the settings.
To check that your offsets were set correctly, jog the camera over the center of the fiducial and then click the position nozzle icon in the jog panel. This should bring the nozzle directly over the fiducial. Then click the position camera icon, also in the jog panel, and the camera should move directly over the fiducial. If you notice that the camera is now mis-aligned over the fiducial, then you need to repeat this step. Failure to tune this will cause parts to be placed mis-aligned on your board!You can then copy the updated coordinates that will show up under the Configuration tab in the X & Y axis fields. Paste these coordinates into the other N2 to N8 nozzles and click Apply to save each nozzle’s offsets as shown below.
While the nozzle magazine actuator has already been setup for you in OpenpNP, we need to adjust the position of the PCB with limit switches installed on it and all the nozzle positions in OpenPNP. We will first adjust the PCB to make sure the limit switches are triggered every time the magazine is opened and closed.Slightly un-tighten by just a few turns the two screws holding the PCB so you can move it freely as shown below.
Next, adjust the PCB by moving it very slowly to the left or right and re-tighten the screws (don’t over tighten!) while toggling ON the actuator for the nozzle magazine in the jog panel under Actuators > Nozzle Magazine. If the motor on the nozzle magazine does a full 360o rotation and the cover returns to the same position, it means that one of the end stops isn’t being triggered because the cover cannot reach it. Re-run the adjustment until the cover only opens or closes the nozzles whenever you click ON, on the Nozzle Magazine actuator. Make sure that the cover is fully open and not partially open.Now that we’ve got the magazine opening and closing the cover properly, we need to adjust the X & Y coordinates in OpenPNP for each nozzle so that the head can pick them up smoothly without crashing into it. Unload all the nozzles from the head to make sure you don’t crash any into the magazine. Navigate to Machine Setup > Nozzle Tips > Click on the first ReferenceNozzle > Tool Changer as shown below.
The distance between the nozzles is 21 mm and there are a total of 20 nozzle holders.
Because these X, Y & Z coordinates vary machine to machine, you need to tune it. If you haven’t loaded the magazine with nozzles, now’s the time to do so. Load them from right to left. It’s ok if you have empty holders in the magazine. We just need to test the first few holders on the right side.Home the machine in the jog panel . Select the Down Camera from the cameras dropdown on the jog panel so you can view it and jog it so the crosshair sits directly over the first nozzle all the way on the right side of the machine as shown below.
For the first location, click the capture camera position icon and the XYZ coordinates will update.
We have a dedicated guide for the Rapid Feeders. Please have a read and come back here afterwards to continue with the setup.
Rapid Feeder Setup
One of the great things about the Rapid Star design is it’s very versatile. You can mount trays anywhere along the conveyor belt using 3D printed brackets secured to the conveyor extrusion for Jedec standard trays or use the included Matrix Tray. Trays should be mounted on the left side of the conveyor before where the board is stopped. This way the empty board can pass under the trays before any components are placed to avoid collision.
Assemble the two included pieces for the Matrix Tray by temporarily using M3 screws with nuts to align and hold the two PCBs together while you solder the two PCBs together.Note: The tray must be aligned 90 degrees to the X and Y axis when mounted in the machine!Navigate to Feeders > > ReferenceTrayFeeder and click Accept. This will add a new tray. You can then set up the tray settings. Note that the Matrix Tray included with your Rapid Star is actually a combination of three different trays because of the different size cutouts. Each specific size shaped cutout in the tray needs a ReferenceTrayFeeder set up for it in OpenPNP. To make it easier for you, we’ve included some of the measurements below for each one. You just need to set the first pick location, offsets (based on measurements below) and tray count.
Example: Tray 10×10 has an offset of 16mm in X and 16mm in Y. There are 22 tray counts (square cutouts). Place the component you will put in this section of the tray in the first cutout on the top left. It’s recommended you place components against one of the corners of the cutouts, that way the machine will always pick it in the center of the component. Jog the Downward Cam over the first component you just placed and make sure the crosshair is in the center of the component. Click capture camera position .You will also have to select the part used in this specific tray from the dropdown list and click Apply to save the settings.
Rapid Star supports all standard Smoothieware firmware Gcode commands. For specific Mcode commands used for various actuators, you can check the config here.
