Hpp JBV clutch and throttle sensor fix

thingiverse

This upgrade to the HPP JBV pedal sensors is cheaper, you need to buy both for my mod, but the sensors will work fine with the standard setup. https://store.spectrasymbol.com/en-au/products/hotpot-linear-potentiometer?variant=40671000592499 (25mm) They cost £15.28 pounds or $30 AU, compared to £87.63 or $172.09 AU from the official site. Wiring is same pins as the standard one (see pic) THESE COULD BE USED AS A DIRECT REPLACEMENT USING THE STANDARD SETUP ! There are plenty of other sensors on this site, but this is the most sensitive of them and the only one to get. I tried the Magnetopot (which requires a different design to this part as it is a much thicker sensor) I used a strong magnet to drive the magnet in the MagnetoPot so there was no physical connection to the pedal slider. But these are very low sensitivity and show erratic progression, which is no good for accurate driving as the raw input drops and climbs erratically during a constant press of the pedal. You will also need a wiper for my mod, https://store.spectrasymbol.com/en-au/products/wiper-recommended This wiper is specifically designed to use with these sensors. The original ball bearing with a spring behind it, I found built up lint and dust from feet then ground away at the sensors when jammed instead of rolling over them. Both the clutch and throttle went on mine. The wiper is also a smaller contact area, making it more accurate (see pic) These use a 6m thread, I tried to incorporate it in this STL, but I made mine using PETG and the slicer added a support all the way up the thread which was impossible to remove, so I just drilled the hole all the way through with a 5.5mm drill then tapped a 6m x 1 thread halfway up from the bottom. I then reversed the wiper into the thread from the bottom to get it started, then used a flat head screwdriver to retract it all the way inside the mount. Once fitted and wired up, I used a screwdriver to adjust the wiper down until it registered in the calibration software. (I would definitely suggest retracting when fitting the slider as it is a tight fit, and you could damage the tip of the wiper during assembly) I then recalibrated using raw data, and it is very smooth and accurate I printed this upside down with supports from the tray as the bottom has a very small recess which is also on the original to provide clearance to the actual sensor. This is so tiny, any infill would be impossible to remove. PS the sideways thread that holds the rose joint link to the pedal cuts easily just using the original bolt as a tap.
