I checked everything you told in the video. I had some a fresh look at my machine, and a broken wire started working. Add it to your condition and results.
It cloud be the stop position sensor not working properly or the notch of the stop position sensor metal disk is not properly calibrated . With a clean qutip clean the stop position sensor to see if this fixes the issue if not verified the notch of the metal disk to see is between the 2 magnets of the sensor and the main shaft at 100 degree. if not calibrate the disk.
