I had read about the early cable X units having issues at the slower speeds, maybe they have worked the bugs out with the newer versions. Barnfind49, how do you find the cable X to work at the slow speeds? I’m considering changing my code to start the motor in open loop mode and then switching to the PID code after 5mph. Currently the needle jumps at start, the PID compares the previous reading with the current reading, so comparing stopped to moving. I think if I get the needle moving first this will eliminate the jumpy start.
