Sensors

The Sensors are 10K linear potentiometers with a 10cm travel that get mounted in a 3D printed frame and secured to the frame with hotglue.  The frame locks inside the leg just under the motor cap, and is held in place by the cap.  This makes them very easy to replace if they ever fail, but they are supposed to last over a million cycles.  I have not needed to replace one yet.

Here is STL File for the sensor bracket.  Print this with 100% infile in PETG or PLA+ for strength.

The top 3D print is the latest design, the lower on is the previous design.  But both are wired the same.

RED - Power (must be extended to go to the end of the sensor)

White - Ground 

Green - Signal

Note: Need a better picture showing the soldering step prior to the hot glue...
