Apologies, the wiring for this project was very simple so I forgot to create a schematic to show how the sensor is connected to the MicroView.  I've attached it below and I'll include a link to this post in my summary.   ...
I did some trial laser focus adjustments and have concluded that the setup that I have is adequate for my requirements.  I was concerned about the settling time from my initial observations but after evaluating some data I've decided that I probably won't achieve a substantially better result.  My initial goal for this project was to achieve a +/- 0.2 mm accuracy by using measurement averaging.  For my laser application somewhere between +/- 0.5 mm and +/- 1 mm is acceptable.  ...

Submit an EntrySubmit an Entry  Back to homepage Project14 Home Monthly Themes Monthly Theme Poll   I've begun to characterize the distance measurement repeatability of the VL6180X TOF sensor.  The testing is in context of setting the focal distance of my laser cutter.  I've empirically determined that the correct focal distance is 39 ...
