Since each sensor is about £4 after tax and another hackaday user managed to get a fraction of data off of it (see the log comments), I'm just going to assume that it'll work fine. With this assumption, I'm thinking of adding a sensor to each side of the LCD head which will allow these possible features:
- Verifying/Inspecting the current layer and cleaning performance.
- This would likely be much better than eye-balling or taking smartphone pictures. It has the equivalent function of the 330fps camera for the #SecSavr Sublime [gd0036] .
- Timelapse
- The scanners apparently have RGB LEDs in there, so a status indicator
- Receipt and A5 document scanner
Additionally, one sensor could be put inbetween the area where PnP components are stored and the build area so that the arm just has to swipe anywhere in the 210mm scanning area for the computer vision software to obtain an image, thus hopefully the arm is already in place by the time the software has calculated the rotational adjustment needed. It may be possible for the X axis to scan the just-placed part to confirm that the component was placed correctly, but a component might be sticking out in the Z and damage the screen
