    I made a DIY Hall Pot as the commercial ones I've been looking at are out of stock everywhere and around $40 each.

    I used a UGN3503U hall sensor from Jaycar and the body of an old pot. Everything is working perfectly except I can only get feedback in JRK from 20% to 80%. I assume this is because the Hall Sensor doesn't go down to exactly 0V and doesn't go up to exactly 5V the same way a 10K pot will?

    Is there anything I can change so the JRK will read from 0% to 100%?

    Fixed. Just needed to edit the Max and Min feedback settings in the JRK config.

    My Motion Simulator:
    2DOF, DC motor, Arduino
    I also use them and they go very well, maybe they do not reach the limit like the 10k pots, but they go fine, and easy to build, and what you say I use SMC3 and can be regulated by software.
