Introduction
The Imago Chip Shot System allows for the acquisition of high-resolution images of chip trays. This raspberry pi controlled system utilizes a motor to increment a tray of chips under a fixed camera, acquires images, and transmits them to a computer to be analyzed.
The software itself is customizable and user-friendly but has been optimized for the trays that you use. We will explore the UI in depth later in these instructions.
Required and Helpful Tools
The only required resources to assemble the Chip Shot are included, which are an Allen Wrench set and zip ties. Each Chip Shot has a new metric Allen Wrench set as well as ample zip ties to route cables at that stage of the build.
Other tools that are helpful to the assembly process:
- Tape Measure
- Square
- Level
Safety Information
The Power Supply is equipped for 120/240 VAC with manual switching. The power supply is already set to the 240V setting. The switch must be toggled to the appropriate setting for your country/region.
Attempting to power on the supply with the incorrect setting selected may result in severe physical harm and/or damage to the system. DO NOT connect the power supply to power without confirming the switch’s setting.
Once the appropriate setting is confirmed, replace the lid of the power supply. Do not open this lid again without instruction from a certified technician.
The system contains moving parts that also pose a risk. A few important things to remember:
- Place the system in a clear location and on a stable tabletop.
- Do not run the system until the entire range of motion is clear.
- Do not make adjustments to any part of the system while the system is running.
- Keep hands clear of the motor while the machine is powered on.

If everything has been assembled, plugged in, and powered on properly, the system operation itself is simple! Most of the operation is carried out by the system itself, but there is a small operator role. This short section will detail that role, and offer some tips that should help in the daily operation.
Operator Role:
- Check the belt tension (see slide 65)
- Load Chip Tray onto inspection plate
- Slide Chip Tray lid into finger slots
- Adjust inspection plate tab with thumb screws to secure in place
- Ensure the tray is pushed back all the way against the stop
- Set the water nozzle offset value (see slide 66)
- Ensure water is toggled on/off according to your preference
- Ensure the nozzle is primed (manually dispense water out of the nozzle to check)
- Plug in the Camera USB to the External Computer
- Open Spinview and connect to the camera
- Start the routine from the Start button or over Serial Connection
System Operation – Tensioning the Belt
The motor belt might need to be tensioned if the belt is too loose
- Loosen the M8 hex nut and mounting screws on the sides of the bracket
- Tighten the m8 screw on the end of the mount until the belt is tensioned
- Tighten the M8 hex nut and the mounting screws
System Operation- nozzle offset
The distance between the water nozzle and the camera must be set
- Home the motor, then Open manual jog screen
- Line up the first slot on the Chip tray under the water nozzle and record the position value
- Line up the first slot on the chip tray under the camera and record the position value
- Calculate the difference
- In settings – General Settings – nozzle offset, set the calculated value
Troubleshooting- Bad Images
- Out of Focus
- Out of focus while machine is still:
- Rotate the camera lens (easiest to do this by rotating the dome light itself)
- Take images periodically to analyze the focus using the manual jog menu’s camera function
- Out of focus while Machine is running:
- Drop Acceleration, Deacceleration, Max Velocity in Motor Settings
- Low/high Lighting
- Adjust Exposure: dial on the camera itself
- Adjust Gain: spin view settings
- Crooked
- The tray was not set in properly. Follow the alignment instructions detailed in the System Operation section
Troubleshooting- Inconsistent Water
- Check that the water tank is full
- Clean nozzle
- Manually dispense water (check software tutorial, Slide 40)
- Loosen the socket head screws and slide the nozzle closer or farther from the tray (check that the valve remains above the chip tray tabs)
- Adjust water “Spray On” Timer in General Settings
Troubleshooting- Images are Crooked
- The tray was not set in properly. Follow the alignment instructions detailed in the System Operation section
Troubleshooting- Software Frozen
- Cycle Power:
- Shut off the power supply
- Wait a few seconds
- Turn the power supply back on
- Allow System to cool
Troubleshooting- Inspection Tray Not moving
- Go to the manual jog menu. Does it say “collision Detected”?
- Yes:
- Tension the belt according to the next slide
- Decrease Acceleration, Deacceleration, max velocity via the motor settings menu
- No
- Cycle Power. Turn of the system, wait 10 seconds, turn on the system and allow normal boot up
- Home Motor
- Yes:
