    Help: Phaserunner Phase Current Troubleshooting

    Hey thanks for the advice. I’m not sure what I did, but messing with the wiring, and I did reset the phaserunner to defaults at one point, but now running the spin test I can get it to complete successfully. Sometimes it doesn’t work on the first try and I got the same error, but then next try...

    Help: Phaserunner Phase Current Troubleshooting

    Thanks for all the feedback. yes, the motor is a geared hub motort.When I short the phase wires and spin the wheel BACKWARDS I get the cogging. It seems pretty clear that there is resistance when the phase wires are shorted, but no resistance when not shorted. The freewheel only goes one way...

    Help: Phaserunner Phase Current Troubleshooting

    yes, I can get through the autotune static test fine. I verified the # motor poles, kV, etc are all correct for the motor I have, based on the info from the Grin website (where I got everything). When I run the autotune spinning test, the motor does spin, but when it stops spinning I get the no...

    Help: Phaserunner Phase Current Troubleshooting

    Thanks for your reply! Based on what I know (admittedly I don't have a lot of info to go on), it seems like a phase short to ground or supply may be what is going on, like you suggest. Just so I am clear, that would be within the motor, or the phase wires going into the motor right, not within...

    Help: Phaserunner Phase Current Troubleshooting

    Update: I got the motor all back together and halls hooked up. Although I can see that the halls are working on the dashboard of the phaserunner config software, the motor doesn't respond to the throttle in sensored mode. It does work in sensorless mode. What is going on? could one of my phase...

    Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

    looks like you have made some progress. I hacked open my display and flashed back to v.11 via SWD, which I was enjoying before. All the weird motor issues went away and seems better now, so I think I didn't fry my motor on the second ride yay! i will move up to the latest version eventually but...

    Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

    thanks for confirming the firmware downgrade over bluetooth doesn't work. My motor may have other issues as I saw yesterday one of the bolts helping secure it to the frame came off at some point from all of the vibrations on rough roads. I don't think I had them tightened enough. anyway I need...

    Hi, Thanks for your work to develop this OSF, very cool! I am a relative novice at this stuff but managed to follow your instructions to flash the SW102 display and motor controller, with the OSF v11 and installed the temp sensor. It was all working well for a couple of days and I had some...
